I Love This Speaker!

Reviewed in the United States on May 5, 2020

Sony has me really impressed. This speaker sounds absolutely fabulous, the lighting is awesome, the Party Booster is fun. There isn't anything I don't love about this speaker. It wasn't clear to me right away how to use all of the functions, but after I installed the app on my phone, it became quite clear. The app is easy to use and the instructions are concise and easy to understand.

For anyone using from a PC or laptop, I had to select the speaker as an output device after connecting to the Bluetooth on my laptop, FYI.

I absolutely love it!

I love this speaker and the sound, however the battery life isn’t as long as I would like, and the speaker doesn’t function properly when outside, if it gets a little warm the volume goes way down, not good for the beach, which is the reason I bought it, since its dirt and water resistant. Works great as long as you keep it inside in the Air condition.

We were looking at the Bose speaker for $129 but bought this one on special for about $60. I've been very impressed with the sound quality and batter life is great. We've had it about a year and I'd easily buy it again over the others.

Major Drawback for me

Reviewed in the United States on June 30, 2018

Verified Purchase

I was drawn to this speaker because it is water and dust proof, but there is a major drawback that probably would have changed my mind on purchasing. While I really like the sound quality when it is charged, the volume will automatically lower when the battery starts to get low. I get it’s preserving what’s left of the battery, but what annoys me is that the volume won’t go back up when you plug it in to charge. The volume will stay low while it’s charging, until is is fully charged again. It takes a while to charge, so it renders it pretty useless in my space for hours at a time. Nothing worse than having to work out to no music! Trying to get in the habit of plugging it in after every time I use it, but it’s annoying that I have to do that. My JBL kicked the bucket, so I thought I would try something new. Kinda wished I hadn’t.

El sonido es de muy alta calidad y tiene una potencia bárbara. En volumen bajo da muchas horas de sonido, aunque a máximo volumen no da más de 1.5 o 2 horas de sonido. Aún así es de asombrar. No le pide NADA a un equipo BOSE.

Se mira bien la bocina, se ve bonita
Es de tela la cubierta
Suenan bien los bajos en en volumen bajo, cuando se sube el volumen suben más los agudos o es lo que yo alcanzo a percibir
En cuanto a la batería la he tenido con volumen al máximo reproduciendo música por Bluetooth desde un moto z3 play y la neta no le dura mucho, si acaso duro una hora y veinte al máximo y empezó a descargarse muy rápido, sospecho que no es que venga mal sino que así es, entonces hay que tenerla conectada si se pretende escuchar a volumen al 80% por mucho tiempo, lo cual es un poco incómodo
Para lo que me costó ($1400) es buena relación producto/precio
Ah y la luz hace que se vea bonita pero no es rítmica por si eso buscaban

Good Bluetooth Speakers at reasonable price

Reviewed in India on October 1, 2018

Got this speaker after searching for ideal device which can meet all expectations. Pros and Cons are as follows.

Pros
1. Nice and compact size - These are ideal size. They are not too big and not too small. Can carry it everywhere in a backpack. Other models of Sony are much bigger and not that portable.
2.Battery life - Battery life is superb. I calculated battery life by listing time every time I used speakers. So in the end I got 10.3 hours of battery backup on a single charge (used it for 2 days and without using its light function which affects battery life). It charges quickly too. Within 3 hours you can charge it fully given that you keep it turned off while charging. Otherwise it takes more time if you use it while charging.
3. Build Quality - Build quality is awesome. Only thing I didn't like was its tiny rubber feet. They are not that helpful in keeping the speaker upright. Sometime the speaker rolls out even with a slight nudge if kept on rough surface.
4. Connectivity - Range of the speaker is good and can easily keeps the signal if you roam around in your house. Call quality is also great if you use it to take calls. People on the other end won't notice that you are talking through speakers unless told otherwise.
5. Sound Quality - As it's a Extra Bass series, the speakers are bass heavy but you can tweak the equalizer to get a balanced sound. The Sony Music Centre app on mobile device let you control the speakers with lots of settings. With Extra bass setting on, you get quite good bass which fills the air and sometimes you can't hear the lyrics if your room is big and empty which causes the sound to bounce back and forth. For me, I turn off the extra bass feature and still get good balanced sound with decent bass. It will be good if you can have a look at them personally before buying to get a good hearing experience.

Cons
1. Battery Backup- If you want more than 12 hours of battery backup then you better go for XB31 or XB 41. But that increases the size of speakers as well as the price.
2. Connectivity - I use this speaker with my S9 Plus, iPod 6th Generation and Macbook Air. 90% the speaker connects flawlessly. But sometimes, it gets connected with the device and then the sound doesn't come properly. It stutters therefore I turn the speaker off and then reconnect. That generally solves the issue.
3. Carrying Case - So far I am not able to find a proper carrying case for the speakers as the material used is mostly fabric which may get damaged in due course of time. It would have been nice if Sony could provide case along with the speakers or at least sell it separately. Currently i carry them in a backpack after wrapping it in a microfibre cloth. SImple solution which works great.
