    Does the mic work well for phone calls? How clear is the voice?
    New User U on May 23, 2018
    BEST ANSWER: It works! Clear enough that I haven't thought about it.
    What Bluetooth codec is used to transmit audio? For example: SBC, aptX, LDAC, AAC, etc
    Jervell C on May 29, 2018
    BEST ANSWER: The only show up as SBC on my devices so I doubt LDAC is supported and I don't own any Apple products so I'm not sure about AAC.
    Can u make phone calls with this product?
    A shopper on Mar 18, 2018
    BEST ANSWER: Yes, and they work pretty good. Voice is only received through the left ear so they can be used while driving rather than having both in at once
    Can you use one earphone at a time? Can you switch to the other one when the first one charges?
    A shopper on May 25, 2018
    BEST ANSWER: ONLY Left side of the earphone can be used as one earphone since L side Is the receiver and has the master connection to the music source.
    What is the expected battery life and do they have any controls for volume, changing tracks, answering calls?
    A shopper on Mar 27, 2018
    BEST ANSWER: Batteries will last 2-4 hours. They have full control of volume, tracks, and calls.
    Does anybody know what model of Comply tips work with these?
    A shopper on Jul 2, 2018
    How well will these stay in during exercise?
    Alexander C on May 25, 2018
    BEST ANSWER: I ran in mine on Monday and am about to go out to run in them again today (Wednesday). They stayed in fine. They're small enough to go into the ear canal and be held in place by one of the folds in your ear that folds inwards.
    Do these have noise canceling technology ?
    A shopper on Mar 14, 2018
    BEST ANSWER: No they do not, but once you have them in, it cuts down on the ambient noise around you a pretty good amount. I use them in a noisy gym with music playing, and i have no problem hearing my music as i would say middle of the road volume over everything else.
    Please describe the fit and how tight they stay in? I have only found a good fit before with Bose that has wings to keep them in the ear. These look great except there is only a round piece that I haven’t been successful with before as they seem to loosen on me.
    Michael S on Jun 11, 2018
    BEST ANSWER: Depending on the earbud tip you use, the unit can stay relatively well within the ear. One friend with this product uses foam marshmallow-style tips for maximum fitting, while I just use a preferred set of rubber tips. Orientation of the unit in the ear will help it stay seated as well. I've had no issues with the earphones falling out unless I'm rolling around on my bed.
    Is there a way to turn them off other than putting them back in the case?
    A shopper on May 29, 2018
    BEST ANSWER: You can hold the button down for a few seconds and it will say “Power off”
    Can you use two phones at once without repairing?
    New User U on Jun 1, 2018
    BEST ANSWER: Yes they will handle two separate devices. Bluetooth setup is simple and only takes a moment even if you wanted to switch to additional devices. They retain the pairing for the last two devices they were set up for.
    How does the microphone hold up in windy conditions? Biggest challenge I have with headphones like these is microphone call quality .
    Bashar M on Jun 4, 2018
    Does the music automatically pause when you remove one earbud?
    A shopper on May 25, 2018
    BEST ANSWER: No, but all you have to do is tap the outside of the earbud and it pauses the music. It's very easy to do.
    Is there only one speaker driver in these headphones?
    German P on May 25, 2018

    What is the frequency response of these headphones?
    A shopper on Jun 2, 2018
    BEST ANSWER: Don't know the frequency response but they are almost as good as my Bose wireless headphones in audio quality.
    What is the charging port? USB C? Micro USB?
    austin s on Jun 13, 2018
    BEST ANSWER: Each earbud charges in the carrying case with contact-pins, but the whole case charges with micro-usb
    How is the volume for calls, and can people receiving calls hear OK? I have another model of Monoprice Bluetooth earbuds and the volume of my voice and microphone is linked to the volume of the callers voice coming in. and It forces me to turn up their voice so they can hear my voice which isn't cool.

    Can you use the mic on a PC if you connect the earphones to the PC via Bluetooth? I.e. to make phone calls with Skype.1 q. ?y
    A shopper on Aug 15, 2018
    How can you tell the right from the left earbud? They appear identical to me.
    Michal M on Oct 10, 2018
    BEST ANSWER: When you remove them from the case or turn them on you will hear "Power on" from each bud. When both have powered on you will hear "Connected" from each one. Then the left one will say "Left channel" then the right will say "Right channel" followed by the left one saying "Second device connected".
    If you only power on the left bud it will say "Power on" and about 10 seconds later it will say "Connected" once it connects to your bluetooth device
    If you only power on the right bud it will only say "Power on" since it is only a slave to the left one and will not not connect or say "Connected" on its own.
    Did anyone get a manual explaining the pairing process and the use of buttons? I received nothing.
    Laurene F on Sep 15, 2018
    BEST ANSWER: Yes, I have the manual - it's minimal but adequate - about 200KB. I'm not sure how to get it to you though. I can tell you that if you put the earphones in your ears and press the LEFT (main) button, you will hear: "pairing" as it joins the right earphone. If your smart phone's blue tooth is turned on , "TWS" will appear as a new device. Click or select it. After the first pairing, when you put the earphones in your ear press the left button, you'll hear "pairing" followed by "pairing with second device" as it pairs with your phone. When you put the earphones into their charger, they unpair, turn off, and start charging. If you have a specific other question, I'll try to answer it for you.
    Will these work with my TV, Iphone, Mac Book, and Ipad?
    A shopper on Jul 9, 2018
    BEST ANSWER: These will work with your MacBook, Ipad, and Iphone as those devices have bluetooth capability. You will need a bluetooth transmitter to receive audio from your TV since this does not have audio in.

    Can these be used inside a motorcycle helmet while riding?
    A shopper on Jul 8, 2018
    BEST ANSWER: They fit, pretty well, within the confines of my ears so I would say yes.
    Do these cut out while walking with phone in front pocket?
    Stephen C on Aug 4, 2018
    BEST ANSWER: I use them while working out in the gym. With my phone in my right pocket, the headphones cut out quite a bit while working out. I switched the headphones to opposite ears and it helped. The main one is the left, so as long as phone is closest to the left speaker, it should be fine.
    How long does the battery last while playing music mid volume continuously?
    A shopper on May 29, 2018
    BEST ANSWER: In my experience, no more than 3 hours. I listen to podcasts often and most of them are about an hour long so I can't get more than 2.5 - 3 podcasts in before I have to charge them and listen out loud or with a wired set of earbuds.
    Is it possible to use this on a motorcycle for music and phone calls?
    A shopper on May 29, 2018
    BEST ANSWER: Without a microphone right near your mouth no earbud set will work for phone calls on a motorcycle.
    Can this device pair to more than one phone and use more than one at a time?
    New User U on Aug 28, 2018
    BEST ANSWER: No. The left earbud can be used independently, but the right earbud is a slave to the left.
    Do these use the same 14.2mm driver as the 8320/15274 etc.?
    Nathaniel S on Aug 4, 2018
    BEST ANSWER: No, they do not.
    How well do these isolate from external sound?
    A shopper on Jun 1, 2018
    BEST ANSWER: As well as any noise isolating earbuds. These are not noise cancelling but they do fill your ear canal so they so a good job at isolating noise. I use them with my lawn mower and, while I have to crank up the volume some, I certainly don't max out!
    I've had problems with ear tips before, how many sizes are they shipped with?

    Seriously great, especially for the price
    I've had these for a couple weeks now and use them during my walking/bus commute to work and back - all told about 40 minutes at a time, twice a day.

    Comfort: These are incredibly lightweight and comfortable. I don't need any fancy tips or contraptions to keep them in my ears.

    Ease of use. Once paired, you take them out of the charging case, put them in your ears, and start playing music. Press either button (left or right) once to pause and twice to skip tracks. When you are done, take them out of your ears and put them in the case. They stop playing, disconnect, and start charging. That's it. Easy peasy.

    Connection. I have had very few problems with connection. If I cup my hand over one ear, that side goes out until I remove my hand. Other than that, I have had no issues with these at all.

    Calls. I can’t speak to this. I haven’t taken a call with these.

    Battery life. This is another area I can't really speak much about. I listen to these for only about 40 minutes at a time. Then back in the charging case they go. I fully charged the case two weeks ago, and haven’t needed to charge it since.

    Sound. As far as priorities go for me, this is near the top of the list. I am not an audiophile, but I love music and I love headphones. The only pair of truly wireless I owned before these were a pair of 1st generation Samsung whatevers. Gear X or something like that. They sucked. They were quiet and the sound was weak and flat. There was zero bass.

    These are kind of amazing and I really applaud Monoprice for what they have accomplished here. These sound as good as $150 hybrid (dynamic drive and balanced armature) in ear wired headphones that have been at the top of my list for some time (Degauss Labs Noir for the curious).

    They are slightly warm, with great bass. Not Beats-style overwhelming bass, but deep, vibrating, warm bass that pops when it should and is almost felt more than heard when that's what the music is going for. But it's never overwhelming. The highs are crisp, vocals are clear, you can hear string changes in classical. I am truly amazed by these. And they are pretty loud. If you have an android phone you are familiar with the annoying volume warning that pops up. I can leave these just below that threshold (which is maybe 60-70 percent volume) and even walking through the very loud streets of Philadelphia, these sound fantastic and I can't hear anything else. Which I suppose could be a con for some - these isolate sound very well. Take that as you will. I will note that when I pause these, I have no problem hearing the outside world and don't have to remove them to hear the cashier when I stop for beer or groceries on my way home.

    Design. I think these look great. Better than the Apple competition (and for a quarter of the price). They are SMALL. The earbuds also connect to the case with magnets so when you return them to the charging case it kind of pulls them in, which is very satisfying for some reason. And they nestle into your ears a bit so they keep a very low profile and are not easy to notice when wearing.

    Features. There aren't any. And in my opinion, that's a good thing. That's it. My Samsungs had a heart rate monitor, active noise cancellation, touch controls for volume, skip tracks forward and backwards - they did none of it well and sounded like crap. They were also big, uncomfortable, had horrible sound isolation, wouldn't hold a charge, looked kind of stupid, and worst of all, they sounded like crap. And that was at three times the cost.

    Monoprice knocked it out of the park on these. I am seriously impressed and very happily surprised at how great these sound and how well they work. They don't do much; they don't need to. What they do, they do really, really well.

    They might not be perfect for you, but they are perfect for me and if I had to replace them tomorrow and pay twice as much, I would do so in a heartbeat and still feel like I was getting a fair deal. At $50, these are a steal.

    TLDR: These are great. You should buy them.

    Also, no one paid me to write this review. I got nothing for free (though, Monoprice, I am available and easily bribed - just saying). I took the time to write all this when I should have been catching up on work email because these are awesome and I wanted you all to know.

    Well worth it for the price, must buy
    These are my first set of these truly wireless earbuds and I have to say I wasn't expecting much, but was kind of blown away by the sound. I have a few other pairs of IEM's (I wouldn't necessarily call these IEM's, far from monitors) such as Fiio F9 pro's, and UE 900s. How do these stack up to those? They aren't close to those in sound quality, but they are also less than half the price and have no wired connection, so you cannot exactly expect the same sort of audio quality from these.

    So next big thing about these is using them for phone calls. I live in a state that is passing a law this upcoming month for nothing but hands free while driving, so I was quickly on the hunt for something that I could use to listen to music with, yet also I could use for phone calls. The issue is I wanted one where I could use just one earbud for certain instances, especially driving since I wouldn't want to be using two while driving. These allow me to use just one at a time, but it's just the left one that will allow you to take the calls, and do all sorts of other things with its one button. The right one is the slave and is pretty much just used for when listening to music in stereo. I should mention that the right side also has a button, but I don't use it nor do I even know what it does.

    Lastly I want to mention the charge case it comes with, wow is it premium feeling, nice metal bottom and the top cover is semi transparent and overall gives it a very premium feel. Honestly, if you are on the go and/or need a wireless device for taking calls on the go, you cannot go wrong with these for $50. To me it was either these or the apple air pods and I don't regret it for a second getting these, plus these dont hang from your ear and look quite stupid, they almost sit flush in the ear, but stick out just a bit, but still not as bad as the Bose competitor to this.

    Very Impressive
    At $50 I had to buy just to see, and with only a couple days use so far I am very impressed. They came charged out of the box so I could immediately turn them on and pair with my iPhone 7 which they did without issue. The sound is clear, I've had zero connection/dropout issues and the volume is not capped at a low Maximum which I've seen with others.

    The case is well-made and has a little heft to it which feels nice. The earbuds snap in when you put them back, and after pulling them out and putting in my ears they turn on automatically and pair, giving distinct audio notifications in both left & right channel. Also, being left handed I really like that the Main Function Button is on the left earpiece.

    The main use I intended for these earbuds is for working out: the connecting wire on my other "wireless" headphones is nothing short of annoying when lifting and running. Having received these 2 days ago I've only had a single workout but I was very pleasantly surprised by their performance. Over 1hr of HIIT cardio they performed flawlessly. They never came lose from my ear during elliptical/stationary bike, felt lightweight the entire time and never bothered me. The one concern I have over sustained use at the gym is with sweat. I hope they stand up to it.

    Good headphones, manual somewhat unclear.
    These headphones sound great and fit well. The charging case is nice and magnets hold the headphones snug and they pop into place safisfactorily. I don’t believe it’s mentioned in the documentation, but you can turn the headphones off by holding the button down for a few seconds. For some reason my right headphone LED turns off after a short time in the charging case but the left one stays on. I’m not sure what the behavior is supposed to be. The documentation says the blue LED will turn on when fully charged but I don’t know if that is referencing the LED on the headphones or the one on the case. Overall, good headphones, documentation needs some work.
    LED goes out. Not sure if it’s charging still or what is happening.

    Can't Beat Them for the Price
    I just got these ear buds last night, and love them so far. I'm thoroughly impressed by the volume and quality of sound these produce, across the whole spectrum. Honestly the bass was much better than I expected. Fair warning, I'm not an audiophile. But for the average listener these are great.

    After the initial pairing, the earbuds automatically connect within ~2 seconds to my S8+ when removed from the case. Music player control is also simple. A single press of the button on either bud will pause/play music, and a double-press will advance the track. I haven't found a way to go back a track yet, but third party software may be able to help with that. I believe the button also works to answer/hang up phone calls.

    The case is well-constructed, feels sturdy, and is smaller than I expected, which is good. It charged quickly, and seems to charge the ear buds quickly too. The buds are securely held in place by magnets. They power on when removed, and power off when returned.

    I haven't had a chance to use them on a call yet. If that experience is poor, I will return and update this review, but as of right now I expect it will be fine.

    Overall glad I spent the $50 on these.

    These are really excellent wireless bluetooth earphones. First, they connected easily to my iPhone and to my MacBook Air. Secondly, they have great sound. I have BOSE blue tooth earphones and these sound just as good and are more comfortable. These are also much easier to charge. Thirdly, they're so easy to charge - just pop them into their charging box and when the LED is solid blue, they're done. (My Bose requires a microscope and fine fingernails to uncover the microUSB port and to connect it). Finally, these cost 1/10th what the Bose cost. I strongly recommend them!

    Great so far
    Bought them about a week or so ago. The are pretty well sized, sound and range is good, battery life has been good. I haven't used them for a phone call yet, so no idea how well they work for calls. The charging case is sleek and they charge in the case similar to the apple ear buds. I'm happy with them so far, will follow up in a few months if I have any issues.

    Just Love These IPX4 Wireless and Sweatproof Earphones
    The True Wireless Sweatproof IPX4 Headphones are simply awesome. Connect effortlessly. Great sound. The charging case is perfect, charges quickly and recharges the earphones quickly. And the price is amazing, less than one third the cost of the Apple AirPods with very similar functionality. I love them and highly recommend them to your customers!

    Only one way they could be better.
    They're great, but have one drawback. The "right" earbud is a slave to the left. You can swap ears with them, but this is a drawback is when the batteries are low. I was hoping to charge one while using the other, but that's not possible. The work around is to get another pair, I guess, and that would still be cheaper than one set of airpods.

    So far: great
    After reading the reviews, I understand why I have trouble buying things when people have reviewed them lower; everyone has different expectations. I'm not an audiophile, I'm a tech guy. But:

    - Seem very loud; at 25% on my Nexus 5x is about as loud as I want to hear them, I can't believe they won't be loud enough for most people.
    - Seem to fit well. I wasn't doing flips or construction, but once I've found the right fit for them ( I turn them so the back of ear is holding them in ) I've never had to worry about them falling out.
    - Battery life seem fantastic. Both the earbuds and the case
    - Calls have seemed decent. They don't have noise cancellation, but they don't say they have noise cancellation so you can't rate them bad for that. But most people have been able to hear me just fine.

    For normal, everyday use, these seem great. To quote another reviewer:

    TL;DR : These are great, you should buy them
