Groundbreaking Sony speakers for smartphones with 360° Circle Sound and Bluetooth wireless music streaming

31 August 2011

Unique visual appeal, 3600 Circle Sound, Bluetooth music streaming, device charging – and more


Sony has created a new and uniquely stylish way of filling a room with music from a smartphone, iPhone or iPod*. Sony Circle Sound audio diffusion technology delivers 3600 sound from a single, compact enclosure that looks and sounds fantastic.

Unlike conventional speakers, 3600 Circle Sound delivers perfectly balanced sound to every corner of the room. No matter where you are, the music always sounds great. The flip side is that it doesn’t matter where you put the speaker. Move it around the room – or house, or garden - and the music still sounds great.

Unlike conventional speakers, 360 Circle Sound delivers perfectly balanced sound to every corner of the room. No matter where you are, the music always sounds great. The flip side is that it doesn’t matter where you put the speaker. Move it around the room – or house, or garden - and the music still sounds great.

The SRS-BTV25 combines the groundbreaking 3600 Circle Sound technology with Bluetooth wireless music streaming to provide a seamless connection to smartphones, including the iPhone, and other Bluetooth-enabled devices like the Walkman, iPod touch and iPad.

Wireless means what it says: no cables, no fiddle – just walk into the room where the speaker is plugged in, establish the link with your Bluetooth device, and play! Its small size, big sound and omnidirectional acoustics mean the SRS-BTV25 can go in any room and be moved easily. All this makes it the perfect music machine, whether you are relaxing alone, with a few friends or throwing a party.

The fun isn’t restricted to smartphones and music players. Anyone with a Bluetooth-equipped product can also instantly upgrade to rich, omnidirectional audio without the cables. Gamers take note.

The SRS-BTV25 looks as technically sophisticated and downright desirable as anyone could wish. Design this good is effortlessly at home anywhere, but you still get the classic choice - black or white?

A special bass-boost function ensures party-perfect beats that will not be drowned out by the crowd. An Audio In port means you can connect any non-Bluetooth players you want to use via mini-jack. For maximum convenience, every time you listen to music from your smartphone or iPhone you can also charge it up via a USB charging port.

Sony design expertise enhances the SRS-BTV25 at every level, from its unique 3600 audio to its huge visual appeal. It is the perfect complement to any smartphone, tablet or music player and it will stand out in any room.

The RDP-V20iP uses the same 3600 Circle Sound technology but acts as a charger and speaker dock for iPhone and iPod models and is controlled via the supplied remote.

It’s truly mobile thanks to an internal, rechargeable battery good for approximately 5 hours of playback. It’s perfect to move around - enjoy music anywhere in the house.

Once again, sophisticated bass boosting means the unit punches well above its weight. It shares the same design DNA as the SRS-BTV25, so it looks outstanding anywhere – in a choice of black, white or red finish.
