    How many watts?
    Julio M on Jul 28, 2017
    BEST ANSWER: I don't know the wattage, but it is great for bathroom use. I use it whenever I cut my hair or take a shower. It's also good for background music in larger spaces. During my grandmothers birthday party she wanted music but not overwhelming. This worked great.
    Can two speakers be hooked up at the same time to the same source?

    BEST ANSWER: Using the auxilliary inputs with the proper stereo splitter and cables, yes, this is possible. You may experience loss of gain as you're sharing the output wattage from your one source to drive two devices. To my knowledge, it's not possible to split the one Bluetooth signal to two Bluetooth receivers.
    Can it run off USB power for indefinite operation? or is it charge-only while plugged in?

    How do I connect my smart phone to this speaker, I have an S8?
    A shopper on Jun 20, 2017
    BEST ANSWER: You search for it as a bluetooth device, and pair it with your device... just like you would for any bluetooth speaker sold in the past 8 years. It will have instructions that describe how to pair your device to this particular speaker.
    Does this fit well in typical vehicle cupholders?
    A shopper on Feb 17, 2017
    BEST ANSWER: Thanks for your interest in our BT speaker. Yes this waterproof speaker will fit well in standard cup holders.

    BEST ANSWER: Deep Blue can play radio through your Phone, remember that it's a blue tooth speaker and a good one for outdoor by pool. Sound is loud and clear.
    How big is the speaker?
    A shopper on Jul 9, 2017
    BEST ANSWER: It is 5" tall and as round as a large coffee mug. Hope that helps. It packs a punch for such a small footprint.
    Is this a radio?
    Belen C on Jun 19, 2017
    BEST ANSWER: No it's a bluetooth speaker, that means you need to use your cell phone or some other device that has Bluetooth to send the audio signal to it and then it will play whatever it is receiving. HTH
    4 - 6 hours battery life? REALLY?
    A shopper on Dec 30, 2016
    BEST ANSWER: We keep this in our shower and use for 10-25 minutes a day and recharge about every 1.5 months so the 4-6 hours seems conservative.

    Will this rust after a year?
    A shopper on Jun 1, 2017
    BEST ANSWER: Thanks for your interest in this waterproof speaker. As a submersible speaker with IPx7 rating the electronics of this devise are protected from water and will not rust. So go ahead and party on and on.
    Does it float?
    Brian S on Apr 30, 2018
    BEST ANSWER: No but it is fully waterproof.
    Does this speaker have skip controls built into the buttons, allowing you to skip forward a track, or skip to a previous track? Some speakers do this by holding down the up or down volume buttons.
    Triston M on Feb 24, 2017
    BEST ANSWER: Yes. One press = skip. Hold the button down and it will adjust the volume. It's a little clunky but once you get the feel for it, it works well.
    Will it play music while submerged? Looking to have underwater music in pool.
    A shopper on Jun 2, 2018
    BEST ANSWER: I would say no. The IPX7 rating is defined as follows:

    Protected against heavy splashing and rain. Must not fail or show water seepage when exposed, but not when immersed. IPX-7 Waterproof Standard. Protected against short durations of water immersion. Max immersion for less than 30 minutes and at a depth of less than 1 meter.
    Can you answer and make phone calls?
    A shopper on May 10, 2018
    BEST ANSWER: No. This speaker does not offer the phone option. I believe that there is a slightly more expensive verstion that does.
    How to tell if it is fully charged?
    A shopper on Dec 25, 2017
    BEST ANSWER: You really can’t. It warns you when almost out. About 15 minuets warning

    Great little speaker
    My company van does not have Bluetooth or an aux plug so I purchased this guy to listen to music I have on my phone and my Audible audio books.i could not be happier with it. Fits inside a cup holder and the sound covers the whole cab even with all the clanking and shuffling of tools in the rear of the van. I use it for about 2 hours a day and fully charged, lasts me about a week before it needs to be recharged.

    Good speaker, slightly annoying
    This is indeed water-proofish. To test it, I set it under a running kitchen faucet. It just continued playing, although the water on top of the speaker distorts the sound. Anyway, it works really well. The battery runs quite a long time, longer than the advertised 4 to 6 hours.

    CONS: The top of the unit has a flashing blue LED that is mega-annoying when laying in bed listening to music at night.
    It has a 'dweeble-dweeble' tone when the battery is low. Good to know, but I wish it could be turned off.

    Good value but just short of adequate sound quality
    Pros: Plays quite low for a tiny speaker. The advertised 90Hz is pretty genuine.
    Quite cheap for what it is
    Sounds way better than anything I've encountered at a similar price
    Waterproof

    Cons:
    Upper mids/lower treble is quite shrill. To my not-very-trained ear it sounds like there are some real problems with standing wave resonances creating sharp peaks/dips in the frequency response. Opening it up and stuffing a little bit of polyfill in sounds like it may have helped, or it may just be wishful thinking.

    Sounds like the upper-bass is boosted quite significantly to try and make up for the lack of real bass. Equalising the 120-300Hz range down a few db helps somewhat, but does not fix it entirely.

    The interface is awkward, adjusting volume and changing track are the same button. It will also beep loudly at you when you change almost-anything.

    Conclusion:
    If you're somewhere shipping is cheap/free then it may be a good deal, otherwise get one of the slightly more expensive more-mainstream options that are likely available from local stores.

    Great sound, long battery life. Wish the buttons were a little more precise with what they did. Sometimes you accidentally skip songs because you were raising the sound. Simple work around though: just raise the volume to max on the speaker then use your phone for more precise sound levels.

    So small but so good. I've been taking it outside for the better part of a day at a time and it's always been my phone that's died first. Also I poured a little water on it to see if it was actually waterproof and my impulse control isn't always 100% and it just muffled the sound a little until it dried off. The buttons could probably have been designed a little better so I don't skip songs every time I try to change the volume just a little, but otherwise no complaints.

    Great Sound for a small package
    I've been looking for a small waterproof speaker to use while sailing and at home in the hot tub. This unit appears to fit the bill. The sound quality exceeds my expectations. It seems to hold a charge long enough that it isn't a problem. I've only been using it for a few weeks near water without the plastic bag that my other speakers required. So far it has not failed because of rain, or splashes. I wasn't planning on a direct submersion for the unit, so I'll let you know if that ever happens.

    Great little speaker
    I've had this speaker for a couple of months now. I'm impressed! Great sound for a speaker of its size and price. The waterpoofing is great—I had this on my canoe with me in torrential rain without issue. Battery life runs long enough for a full day of paddling with music, haven't reached the end of the battery yet, but my guess would be approx 8 hours of playtime between charges. I would buy this again, and will, if the need arises.

    A Good Waterproof Compact Speaker That Gets the Job Done.
    I purchased the Deep Blue Sub75 to take with me on my paddle board. I think it performs pretty well for such a small speaker, and is a big upgrade from the speakers on my Iphone. Both highs and lows are clean,and the Bluetooth connectivity works well. I plan to take this with me on other outdoorsie trips as well.

    I found the controls on the unit a little cumbersome to use, so I mainly control the unit through my phone.

    Overall, I managed my expectations for this unit and I feel that it fills the niche I bought it for, well.
