Basic sound quality appears to be very good. It makes a great PC speaker. I especially like that you can have multiple audio sources and switch between them with the included remote control.My only gripes with them are:-1) The "Soundfield Spatializer" didn't work on the first unit that I received. I didn't know what to expect for this new feature, but a marked difference in the tone and volume of the audio playback didn't sound like the correct response.however, Edifier were good enough to send me a second unit to replace the first one, without first having to return the defective unit. (Good customer service!) Now, on the second unit the "Soundfield Spatializer" does switch between a very focused and a disbursed sound field, as the description says.2) The range of the tone controls seems to be very limited - I found it hard to notice any effects on the audio I was listening too. I used fixed frequency tones to verify that they did actually work, but, as I said above, the effect on your music may be hard to discern. Audible Base starts at about 45Hz and the volume of this can be significantly reduced or increased. With other frequencies the effects are less discernible.Overall, I think that these are great speakers. I haven't tried the "Soundfield Spatializer" and sub woofer output, so I don't know yet whether they are useful or not.

I was surprised about this speaker. I read the reviews and they were spot on. Small speaker that puts out really good sound for its size. Charged it up and it played music for at least 5 hours and still was going.

Volume is not loud enough. Still can't hear over teens and dogs. Otherwise, it's good.

For the price, this is portable speaker has a good sound. Glad I ordered it!

Sounds good, love the handle, battery life about 3 hrs

Speaker was solidly built and worked perfect. Connecting was easy and fidelity is surprisingly good for such a small speaker. Would have liked a higher maximum volume, but for anything less than a party gathering, this Bluetooth speaker is very good.

I had a bose speaker and this one is every bit as good. Even better because you can link two.

Meanwhile working well, haven't had a chance to measure the battery life time, will do.
