The 30 and the 20 are good quality MONO

Very good sound quality

The Sound quality is of course great being Bose but its worthless when music cuts in and out constantly across four speakers added to my Soundtouch app

The sound quality is phenomenal but you have to remember that Bose sets their speakers for max bass out of the box so for some listeners they have to be adjusted, which is easily done with the app

I'd say it's certainly worth investing a few hundred dollars in if you're looking for a quality compact sound system.

Second handed or third cheap... and the costumer service forth or fifth cheap quality... incredible with such prestige and price you got this back

of gotten top quality app and second, I was looking for full integration with Alexa.

Easy to set up and the sound quality is awesome.

The Best Sound Quality speaker comparing to other wireless speakers in the market

It filled my houses first and second floor with rich, clear, delicious sound and it wasn't even as loud as it could go!Besides the astounding sound quality this product sports Bluetooth support and the ability to have 6 preset internet radio stations

Only what is available on their ap, aux, and bluetooth are available and the aound quality of the bluetooth is aweful!

Quality sound, 101% satisfied

Audio quality is great, and operating design is with remote control simple, plus Bose has SoundTouch software available for download on your PC or Mac to allow local network control the unit for more functionality.

I bought it for my uncle, the quality and speed of delivery were perfect

The sound quality is not very good

I rather have simpleness (like before) but sound quality

it's user friendly and the sound is clear and great quality

In summary, no setup issues whatsoever and great sound quality

The sound quality is excellent.

The sound quality is great

Amazing sound quality.

To summarise: Great concept, very good sound, crappy quality (in my case, anyway, the Portable went dead after only one month of giving me the above error messages :) - had to get a new board AND pay for

Bose is simply the best quality product for the money.

Good sound quality

Surprisingly poor audio quality despite reviews

Sound quality marginally good

With that said, Bose doesn't claim that the SoundTouch would offer such support and instead intends the device to be a provider of reasonable sound quality for streaming content from providers such as iHeart Radio, Pandora, and others

Bose Sound quality is amazing as you would expect.

The sound quality is amazing and this unit gets LOUD

I think it's an attractive, high quality audio source

Sound quality very poor in my opinion

With respect to sound, I love the sound quality that this unit puts out; nice clear tones and rich bass.

Bluetooth has limited range and audio quality.

Love the sound quality.

As usual, the sound quality for Bose equipment is great.

Despite my negative impression I'll keep this product because a) sound quality is good, b) I have a device I can dedicate via Bluetooth streaming and leave within range, and c) because the product is unobtrusive, as good speakers should be.

sound quality is great!

Very good sound quality

Great Sound, great quality

Great Quality Good pricing looked around at several

I have been suggesting this unit to everyone because of the amazing quality.

This plays them all with superb quality

The biggest/only problem I have, which continues to baffle me, is the TERRIBLE quality of the software.

The sound quality is outstanding!

The quality of the sound is outstanding!

The compression techniques used on the internet and Bluetooth do degrade the sound quality, so this is probably the reason for the slightly less than stellar sound

The sound quality is pretty good but that is it

We like the sound quality but the set up was very vague and left out steps.

This product will if you have never experienced astounding sound quality like what this offers honestly shock you like it did me

The biggest advantage of the system is the sound quality and loudness from such a small box

The sound quality of the SoundTouch is also excellent and right up there with the Bang and Olufsen streaming players.

The sound quality is great and it is easy to transport almost anywhere.

The sound quality isn't even that good

Sound quality is much better than ST 10

Typical top-quality Bose sound.

Love the quality of the sound

The build quality is excellent and I expect it will last many years, like other Bose products I have owned over the years.

We're very disappointed; the sound quality of the unit is good, and it works well with Spotify, Pandora, and internet radio.

Sound quality is very poor, especially on the highs

; The sound quality is marginal at best, save your money and buy a cheaper better sounding unit.

It has really crisp clear sound quality!!!

The Bose speakers and Sonos speakers both have excellent sound quality, but the versatility of the Bose puts it way above the Sonos for me.

great quality and sounds amazing.

excellent quality, nothing like BOSE!

I would highly recommend this project the quality is amazing.

The sound quality is amazing for such a small speaker

Awesome speaker with amazing sound quality!

Excellent quality of sound, easy to maneuver and set

For a tech Luddite like me, it was just amazing to hear that great, fat Bose sound, as well as be able to access the thousands of world-wide internet radio stations.

All in all I like this a lot better than Sonos
