Sony ULT Field 1 Waterproof Portable Bluetooth Speaker (Grade A Refurbished)

Awesome. Love them!  Would purchase the TWO combined again. Great stereo sound with TWO Bluetooth'ed together.  Battery life seems very good even with the enhanced sound button on. They connect effortlessly too. And are durable. Mine have fallen to a carpeted floor 3 TIMES because I placed them in precarious spots and their inherent bass caused them to move just a tiny bit enough to fall. Place them on a table top, etc. and no problems. This was my definite user error, instead of any kind of fault.  I was looking for sound equal to, or better, than a 1982 Walkman I bought but never forgot.  I definitely wasn't disappointed! These are by far, better sounding than 3 other name branded Bluetooth speakers I have purchased. And those, weren't cheap ones either!  They possess a balanced sound profile with enough bass too. Clean sound across the entire spectrum!  "Thrilling" really.  Just don't expect them to sound like there's a dedicated subwoofer attached. But again, I find the bass response very pleasing. Super easy to grab as a pair and carry around too. Genuine "Grab and Go" anywhere!  They'll accept either a "Normal / Standard" speed charger or a standard "Fast charger" too. They adapt. Just not something like "Super Fast" chargers. You need to not provide too much "voltage". With varying "amps", they only draw exactly what they need. I would rate these very highly. And would DEFINITELY purchase these TWO again.  They will easily fill a large living room, and a good portion of an entire home. Volume is very good and clean even turned all the way up. No complaints here. -----------------------------   * ADDITIONAL INFO I PROVIDED IN "AN ANSWER" TO A QUESTION, POSED ELSEWHERE. BUT, WELL WORTH READING I BELIEVE: I have TWO Ult Field 1's and run them in TRUE STEREO. They automatically connect, even just turning 1 of the 2 on, or BOTH at the same time, from within the appropriate app! If you notice, the Ult Field 1's are THE ONLY Ult Field in the full lineup of speakers which ACTUALLY DO STEREO. The other models ALL connect in "Party Mode" MONO. Now, here's where I think your issues arose. The Ult Field 1's MUST, FIRST-EVER be "stereo paired" in the Sony *Music Center* app, NOT the newer "Sound Connect" app. However, once Bluetooth stereo paired in the Sony "Music Center" app THE FIRST TIME, they'll THEN work fine in Sony's "Sound Connect" too. I found, I simply prefer using the "Sony Music Center" app BETTER, regardless! It seems to provide additional features for the Ult Field 1 over what's available in "Sound Connect". And AGAIN all this, really only applies to the STEREO SEPARATION which ONLY the "Ult Field 1 model" can provide. "Party mode" may be LOUDER MONO, but never actually SEPARATES into 2 different channels for TRUE STEREO. I only know all this, partly because I read the instructions carefully, but also because I loved the Ult Field 1's STEREO PAIRED together so much, that I came back and was seriously looking into the larger versions offered. That was, until I found NONE of the larger speakers provide true stereo SEPARATION when paired and placed several feet apart. This is really because the larger models already separate into STEREO WITHIN *ONLY* THEIR OWN CASE, and NEVER actually do provide TRUE STEREO SEPARATION because it's already locked-in to their, each separate case. I'm keeping my Ult Field 1's because they're the only true way within the entire lineup, of achieving TRUE SEPARATION (of up to several / many distinct, feet apart)! It's one thing I believe "most buyers" aren't actually noticing about the entire lineup. I'm SURE the larger units provide better INDIVIDUAL sound, however when "paired" together they never truly form a separate-able stereo pair. They instead just make additional "volume" and "space-filling" sound in their "Party Mode" of up to many, multiple pairings. I wonder if you initially PAIRED in "Sound Connect" and haven't actually achieved TRUE STEREO SEPARATION yet! If not, DELETE all instances of the speakers existing within whatever apps, then re-Bluetooth pair within Sony *MUSIC CENTER* FIRST. Then, set your speakers several feet apart on separate sides of your head, and truly ENJOY! I'm keeping my little Ult Field 1 pair. Because they provide something special to make up for their otherwise tiny size: TRUE STEREO SEPARATION! (I sincerely hope I didn't mix up the TWO app names within this composition. If you wish to review your "original" instructions, but otherwise threw them away, they can be re-downloaded from Sony's website, of course.)
