Great Speaker

Reviewed in the United States on January 22, 2019

Verified Purchase

This thing has sound that rivals small stereos and premium PC speakers. The sound is almost studio like and had a perfect balance of bass, mids and highs. I not only use it with my phone over Bluetooth but also the aux input for my PC when I’m gaming and don’t want to wear headphones. Also I have a ps4 that’s HDMI’d into a computer monitor with terrible speakers so again when I don’t want to use headphones I’ll plus this into the DualShock 4 headphone jack and the sound quality is still very very good. It’s a great replacement in my opinion for small speakers if you’re low on desk space and have multiple things you can use it for plus it’s portable so you can take it with you when you leave.

Better than JBL

Reviewed in the United States on April 7, 2020

Verified Purchase

Even knowing JBL's are more popular among younger customers as it provides boomy sound for EDM, I wouldn't recommend them for anyone else who wants to hear more than just bass. The problem of JBL speakers is that they don't provide any way to reduce bass and hear more mids/highs. Sony does have this option via app - there are sound profiles and EQ in the app, so you can choose what you want to hear.
Sound quality overall - compared to Flip (4?) and has more balanced profile, while Charge and Xtreme have too much bass. If you need more power, take XB41 - it's powerful, easily compared to Xtreme, but again, you can tune the sound.

Pretty impressed by the sound of this. We gave this as a gift and we liked it as well. Good sound, battery, and portability. We gave the little bigger one as a goft as well, i think that one’s sound was a touch better but why wouldn’t it be of it were a lottle bigger? This one would be great for a kitchen, office, bedroom, maybe a garage.

Great Little Speaker

Reviewed in the United States on January 27, 2019

Verified Purchase

I bought this around Christmastime new for $58. Best small bluetooth speaker I have heard, plenty of low end and very loud for its size. The only disappointment is the battery life which is okay if you use standard mode w/o lights, but it will probably not achieve the advertised 12 hour battery life if you listen above 50% volume most of the time. The main annoyance here is that Sony limits the volume to 50% once the battery life reaches 10% or lower. According to Sony this is to protect the circuitry, although I have never had another speaker do this. It is IP67 rated, making the XB21 a great shower speaker. If you can get one for less than the MSRP ($99) than I would recommend it. It supports Sony's LDAC codec (Android 8.0 or higher, not available on iOS) and you can either pair two (Sony) speakers for dedicated left and right audio channels or pair up to 100 of them together so that's cool.

Older model, but works fantastic! Delighted it was just what I needed! 👍🏻👍🏻

Reviewed in the United States on April 29, 2020

Verified Purchase

Great brand. Found on Amazon for reasonable price, definitely recommend! I wanted a sound bar for the TV. But they are expensive & too big for my entertainment console. You have to buy a double sided audio cable & then you plug one end into the headphone jack in the back of the TV. The other end goes to the audio input jack of the Bluetooth speaker. Then you simply plug in the USB charging cable to the USB slot in the back of the TV so it stays charged. Lastly, if you want to use it as a speaker for your phone, pair it to your phone first but then you have to unplug the audio cable from the back of the speaker so it changes gears to receive the Bluetooth signal from your phone. If you leave the audio cable plugged in, it gives preference to audio in. It cannot produce sound for your TV & phone at the same time.

Purchased as a Xmas present for my 11 yo son 2 years ago now... spent $35-40 on it at the time and we have definitely gotten my money worth! He jams out on this all the time and it really bumps! Not to mention he loves the lighting effects.

Above average sound quality, but fussy pairing

There's a lot to like: good sound quality and material quality - seems like a well-made little unit. Very portable. Looks good.
And there are a few things not to like: most importantly, a fussy pairer, seems it too frequently needs a charge, and charging cord is only 20" long.

You should try this Bluetooth speaker

Reviewed in the United States on August 8, 2018

Verified Purchase

I have considered myself an audiophile since I bought a stereo worth more than my car in the late 70’s . I had a JBL clip that I tried for a short time and was dissatisfied with the controls, it would come on intermittently and was actually obnoxious. I returned the JBl and bought the Sony and I am dramatically impressed!!! The bass response for the size and weight is incredible! I cycle a lot and this unit weighs almost two pounds but I calculate that my workout is enhanced because of the Sony Bluetooth speaker. I couldn’t be more satisfied and I would strongly recommend you try this before ANYTHING else.

Excelente producto, calidad y durabilidad muy buenos.

Reviewed in Mexico on August 23, 2018

Esta bocina tiene todo lo que necesito para escuchar la música en un volumen moderado en un departamento mediano. En mi departamento los muros son muy gruesos (hacen que no llegue señal de wifi a 6 metros del módem), pero no he tenido para nada problema con la conexión bluetooth de esta bocina.

Me gusta que tiene NFC y bluetooth 4.0, yo la compré color negro y las luces encienden color blanco, tiene entrada de audio con cable y únicamente el cable micro usb (sin el cuadrito del enchufe), tiene una función de party boost, con la que al golpear/agitar la bocina, produce un sonido para que le pongas tu propio ritmo a la música, que la verdad se me hace algo que no da un valor agregado al producto.

Algo que pudiera mejorar, es la forma de confirmar el porcentaje de carga de la batería que puede ser por medio de la app de Sony, activar un señalamiento de voz que interrumpe la música (este se puede activar o dejar apagado y solo escucharlo al tener muy baja la carga), o presionando un botón en la parte de atrás para escuchar el porcentaje de carga.

SONY ojalá hicieras una actualización del software para que las luces parpadearan de cierta manera específica al tener poca batería.

Es un excelente producto, no duden en comprarlo.

Reviewed in Mexico on March 29, 2019

Verified Purchase

el sonido es envolvente, la calidad que uno se espera de un equipo sony de este precio. tiene un sonido fuerte sin distorcionar el mismo, la batería es muy buena, da muchas horas de autonomía, aunque aún tiene el problema de cuando se encuentra a un 30% de su capacidad, el sonido baja para ahorrar energía. esto debería de ser opcional ya que uno espera tener el mismo rendimiento hasta tener 0% de batería.

la estabilidad del equipo, es un poco pobre, las 4 gomas que usa como base es inestable. un leve empujón y la bocina rueda, así que hay que tener cuidado de no se caiga. llevarla en el tablero del auto, imposible que no gire para caerse a diferencia de su versión anterior SRS-XB20 .

el efecto de percusión incluído cuando se toca, es innecesario en la mayoría del tiempo.
