This is my second Sony ULT Field 1 speaker, as I wanted a pair for stereo use. The result exceeded my expectations. The stereo sound is excellent. Even at low volume the sound is clear (especially in ULT mode) making it perfect for background music.

The overall sound of the Sony ULT Field 1 is impressive for it's size. music fills our whole apartment sounding like a Hi-Fi stereo system with supreme clarity. Don't expect the bass to blow your socks off but it gives a full and balanced tone which is very satisfying.

I'm happy with my purchase. It was between this and the JBL Flip 6. I'm sure the JBL would have been good too. With regards to the Sony ULT Field 1, I like the style and design, the fact that it has flat sides and won't roll over. The battery keeps going long enough so as not to be a bother.

5 stars, no debate. This speaker delivers clean sound with zero distortion, even when it’s loud. Mids and highs are crisp, and overall sound quality is top tier for a portable speaker. Sony cooked with this one. Very happy with my purchase.

Sony ULT field 1 bluetooth speaker is my first Bluetooth speaker and the sound is good battery live is strong even on the ult mode on it will last up so 10hours and 50minutes better then they said it would be try it for yourself don't take my word for it or money spend it time to take the party with...

I bought one of these ULT Field 1 Bluetooth speakers as a travel speaker but was so impressed with the sound and the fact that you can pair 2 to give full stereo that I bought another one this week. They sound amazing as a pair with one giving the left and the other the right stereo channel.

I am surprised just how good this little speaker is. It has great depth for base and the overall sound is really good. The volume is exceptional and mine is mostly on number 1 or 2 because it really distributes sound well.

I already own one of these and purchased this one for my partner..... it's that good! Great clear sound with lots of bass packing a big punch into a relatively compact unit. Simple to set up. Battery life is impressive too; mine has never run flat without warning. Highly recommended.

Very happy with purchase. Brilliant sound and reasonable base, good for a small room and portable to move around when needed.

Great Speaker for home, Garden, Gym. Great sturdy build, sound quality, bass-tastic and ace lighting effects! Impressed on day 1.. hopefully will remain reliable.

super bien la calidad del sonido todo sin problemas
