Do these power off (sleep) automatically when there is no input? Can they power back on when there is audio input?

BEST ANSWER: No they do not. There is an on/off switch on the rear of the speaker. I have left them on at my office and were on when I returned the next day.

I use a pair of these on my TV and, no, they do not turn off when there is not an active signal. The pilot light remains on.

These don't have speaker grills, right? Is there a way to add aftermarket grills to keep kid's fingers out?
Luke B

BEST ANSWER: There are no holes so I don't think you can add grills, but the plastic is hard enough that if kids touch it, I don't think theres an issue. It seems to be feel super solid / thick.

Does the amplifier inside the unit have some sort of filter that cuts off low volume signals? If I set the volume low, or if the input signal is quiet, the speakers won't play any of it. There are times when the signal levels go up and down smoothly but the sound cuts in/out completely on and off.

For the money these speakers cannot be beat. The bluetooth connection worked seamlessly. Using these with a blue tooth turntable and they produce plenty of sound range to fill the room.

Big sound in little speaker
Sound Quality, the speakers are fantastic. I am using it as pc speakers with Modi III dac and the experience is immersive and the soundstage is very large from where I am sitting. Good dynamic range. The bass hits perfectly for my Music and gaming needs. Do not expect it to shake the room, but those little speakers can shake the desk.
One cosmetic flaw on the speaker is of note. However, Customer service has been on point and taking care of the replacement so no ding there.

Great speakers!
Great sound quality. Easy to use. To bought them to connect to my audio-technica turntable & couldn’t be happier. They also connect to my iPhone just fine. Easy to pair. I love the sound quality.

Mind blown.
I've been on the verge of becoming an "audiophile" for quite a few years now. These speakers have pushed me off the cliff and I'm falling headfirst into the decimation of my technology budget. I bought these for my desk after buying some 4 and 5 inch MP (non monolith) speakers for a couple zones in my whole home audio solution. Those speakers were great for their size, so I decided to buy these for my office desk. I had high expectations for these and every single one of those expectations has been exceeded.
These little speakers put out a truly immense amount of sound for their size. On top of that everything is so clean and crisp.
They are replacing a couple floor standing speakers with multiple 6 inch drivers and tweeters. Can these get as loud? Of course not. But the richness and fullness of the sound is night and day. Gone for me are the days of trying to fix speaker and amp quality issues with an equalizer. I can't wait to get a monolith 2.1 setup in my living room!

These are insanely good.
I was originally going to buy the T0's by Vanatoo, but at almost double the price I thought I'd take a gamble on these. Turns out it paid off, these are probably the best sounding speakers I've ever owned. They're nothing short of amazing. Z-reviews backed it up, so happy with this buy, I wish they had the white in stock but honestly they're amazing.

These are awesome

Fantastic value
These have been fantastic. I love that I can have them connected to both my work laptop and my desktop (using 3.5mm and RCA->Headphone Amp/DAC->PC) The sounds is clear. I do wish that they had a bass-out option to them though.

First Pair was a Dud, Second is Great
Review title says it all -- the first pair I got had a broken volume potentiometer, so the volume wouldn't change when I twisted the knob. I contacted Monoprice support, and got a replacement pair. The RMA took about 2 weeks, but I'm happy with the second pair.
The stands are great, the speakers are crisp and can get _loud_ without much distortion. I didn't think I would use the bluetooth function, but it's actually very nice. I just wish I could disable bluetooth when I don't want to use it (my phone keeps pairing with these speakers instead of my headphones).

Impressed--accurate powered monitors with solid build quality
Wanted to free up some desk space and replace a worn-out pair of passive bookshelf speakers for my office. Decided on the MM-3 and its one of my favorite purchases this year. Impressive bass for the size (after being broken in), accurate (maybe a bit bright at times), but paired with a lossless audio file these really shine.
Fit/finish is strong for the price point and I like the fact these come with small wedges/bases to sit.
Cons/negatives:
-Holy moly are the cables excessively large to connect the two speakers. These make it a bit awkward for placement and protrude from the back
-Main power switch is on the back. Why? Seems like it would be easy enough to integrate this into the front volume knob.
-There's a detent in the middle of the volume knob (50% volume level)--why?

Great speakers for a great price
This was a huge upgrade at a great price for me. I’ve been looking for small desktop speakers that were affordable and sounded great without spending too much and the MM-3s were perfect. I got it on sale and for a hundred bucks, it was well worth it. It was easy to set up and has a wide and much clearer soundstage compared to my last pair of Logitech’s.
My only gripe is that the master speaker is locked into one side (left), and I would much prefer the master to be on the right. This might be more of an issue if you’re playing games but I don’t find it that huge of a deal if all you’re doing is listening to music. Though it can be off putting when someone in a movie talks and sound comes from the left but the character is actually on the right.
