Good product with great sound quality, but don't put it too loud!

This set has a ver sleek and space-saving design, doing its job incredibly well. The included remote control works very well, as well as the controls on the set itself. The sound quality is well above average for its size and, understandably, increasing the volume also increases distortion. The only annoyance is that it has a very bright power LED that stays on even when the unit is in standby - in a dark room it makes a difference (nothing that a tape can't solve, though).

I like the speakers, they are ergonomically pleasing, the controls are easy to use, and the sound quality is superb.  I deducted one star because they are not nearly as loud as my old 500W speakers.  However, I'm nearly 20 years older than when I bought my old speakers, so I don't foresee a time when I want loud music again anyway.

Giving 5 stars because I am happy about the product. Price quality rate is great. Battery is impressive. Sound is clear. Can not wait for playing it loud outdoors. It certainly made my experience of listening to music in my room better than from my laptop. It connects super easy to all apple devices.

BUT, I have the impression that it feels better at high volume, rather than at low. There is certainly distortion, and if buying for "room/indoor consumption" I would recommend spending something more for a better sound quality.

I am basically very happy with the sound quality, however, I disconnect my calls very often accidentally because it is on top of the volume control.  The volume control is just too small.  The on/off button, to my opinion, should be located somewhere else, therefore the volume button can be bigger.  This is a very simple thing that the manufacturer should have thought of when they designed this product.  That is not a brain surgery

It is VERY loud when it tells you it is connected.  Other than that, I am pleased with it not only for listening to music off my phone, but also using it as a hands-free device when making a calls.  Folks I call say the sound quality is really good.

Overall, this is a good product. Easy setup, good sound quality, good build quality. But one thing that I discovered is that the inputs aren't stereo. The inputs are mono, which isn't in the product description.

The quality of the product is very good.
The headsets are very comfortable.
The bass anyway is way to high for me.

I had to make special EQ for these headsets.
On iPhone you cannot make manual EQ and the only option is to try all available predefined EQ's.

I have noticed other people complaining that the headsets are making a noise when you move the cables.
You get a noise indeed, but the noise is not coming from headset. The noise is transmitted mechanically through the cable (vibration of the cable).

Pros: You can hear stuff around you! Good sound quality! Good for specific needs.
Cons: Quiet, one size doesn't fit all, under-featured.

These took a bit to get used to. I have a larger head, wear glasses or sunglasses almost all the time I'd be using these headphones, and I have thick, shoulder-length hair. The fit is snug without being too tight, but they shift enough that sometimes it feels like they're trying to close my ears. The behind-the-head bit is not adjustable. I actually found that they were most comfortable when my hair was down, the headphone piece was UNDER my hair and I was wearing my glasses - this combination seems to keep them in one place best. They're impossible over my hair - if you have a large hat size, don't buy these without trying them on first.

They don't shift a lot - just enough when running/walking to be a little annoying. They're actually great at my desk, sitting still, but they still shift a bit! If you work in an office and want to wear headphones but don't want to be startled every time someone walks up behind you, these would be a great solution.

The sound quality is quite clear - I recommend them for podcasts and music, though I think they lose some bass.  However, I found the sound quieter. A very noisy gym would drown out my podcast or music.  I was surprised there are no controls or other features on the cord. This does mean they're fairly weather proof, but seems like a throwback...

I bought this because I am so underwhelmed by portable bluetooth audio players.  Their bass range is so tiny.  And they are so overpriced.  I feel like we are all being dooped.  So, I thought to myself why not a plug in boom box like the old days?  Just throw some D batteries in it if you need to take it somewhere with no power.  Anyway, back to the review . . . The bass is EXCELLENT.  very deep and very loud.  But . . . it rattles the box.. kind of annoying (and why this is only getting 4/5 stars).  Plus at very loud levels you cannot have the extra bass on bcus I fear the speakers would blow (again, poor design).  But . . . even with the extra bass off, it thumps like a beast.  Only other gripe (since I'm a bit of a audiophile) is that they really should have put in a couple of tweeters at the upper outside corners.  It could use a bit more fidelity in the highs.  But it's ok... for $170.  All around very satisfied.  Bluetooth works wonderfully, as does the line-in.  Haven't tried the guitar or karaoke yet.  Great product!

I bought these to use when trying to sleep during the day when I have to work odd shifts. They do reduce a lot of the background noise and the sound quality is quite nice with the noise reduction on. One complaint is that the difference in the music level from when you have the active noise reduction on verses off is quite apparent. So is the fidelity. With the noise reduction on, these headphones can be a  lot louder when playing music and the upper mids and highs really come forward. With the active noise reduction off, the headphones sound dull in the upper mids and highs, and are not as loud. My only real issue with these is that the ear cushions have started coming apart at the seams after a year's worth of use, thus the four star as opposed to five star rating.  As for noise leaking out when playing music, if you have to crank music so loud that others can clearly hear it bleeding out of these headphones, you must either be deaf or you just like playing music at dangerously  high sound pressure levels. These headphones are very efficient and can easily produce sound pressure levels above 100db. Even 20 minutes listening at such high levels can permanently damage your ears. If you listen at normal levels, the noise emanating from these headphones is minimal to nonexistent.  All in all, a good product at a much more reasonable price then the grossly over priced big name product that is more synonymous with noise canceling earphones.

Has a great sound, but not very loud. I tried this in the store and was surprised how awesome the sound quality was. Once I used it at home, it just didn't get loud enough while maintaining the sound quality to be worthwhile to keep. If used at a party or even just around a few people chatting, it would never be heard.

I didn't buy it for the lights, but they were a cool feature!

Price-wise it's a good product for the quality of sound. Overall it's a great speaker at low to mid volumes, but if you try to play it loudly it doesn't quite hold the higher volume before sounding crackly.

This is an excellent product. The cooling fan works very well and the speakers are nice and loud. There is adequate amount of mid bass,  it's also very sturdy. My only complaint is a bit of speaker hum when using the 1/8" plug and the fan. The sound is cleaner when using the USB connection. Highly recommended for smaller laptops!

Reception has greatly improved compared to earlier models and signal fade is nearly not an issue. Voice tuning is a nice addition and helpful. My main issue with these headphones is the extremely low volume. Even when turned to their loudest, they are still fairly low in volume. I am assuming the manufacturer limits the volume for various safety reasons, but it is annoying. Let the consumer decide how loud they want to play their headphones!! Increase the volume level and you would have a great product.

this product is very good, mainly for the price. But it doesn't have that quality of sound I was waiting for

the sound is great! crisp, strong, well balanced.
I just wish it didn't make those sounds when turning on/off and when pairing. if you have any tips to turn them off I would really appreciate them.
I just got it a week ago but i'm very pleased.
I do wish it had it was a bit more portable, maybe a handle or something.

This is a nicely designed product with a very big BUT:
The difference between max volume and min volume is very slight, so the two people listing would really have to have *very* similar tastes for how loud they like things.
In addition to not lowering the volume very much, when you do lower it, the sound is very muffled and less clear.
