Powerful sound from a slim profile
Despite being compact in size, the SRS-X55 delivers 30 W RMS total output power through 2.1 audio channels. Experience full-bodied, balanced audio with two 1.50 in full-range speakers and a 2.28 in subwoofer — so you can enjoy your music with clear, powerful sound whatever the volume.
Boost your bass with a woofer and dual passive radiators
Get big bass lines from a compact speaker. Dual passive radiators work with a woofer and react to the movement of air through the speaker, artificially creating space in the speaker cabinet. This space allows more air to flow through the speakers, enabling even smaller units to deliver superior sound — especially at low-end frequencies.
S-Master digital amplifier: true sonic purity
Enjoy the best of digital audio with the S-Master digital amplifier. Using a simplified, full digital signal path, the S-Master amplifier reproduces digital audio signals without the multiple analog stages required by conventional amplifiers. The result is not just more power, but significantly less distortion caused by heat build-up.
DSEE restores detail to your digital music
Boost the quality of your compressed music files. When an original music source is compressed, it loses the high-frequency elements that add detail and richness to your favorite tracks. The Digital Sound Enhancement Engine (DSEE) faithfully restores these to produce high-quality sound that’s closer to the original recording.
ClearAudio+ enriches your music
ClearAudio+ is a unique technology that leverages Sony's expertise in digital signal processing developed over generations of perfecting sound, it delivers a rich, high-quality listening experience.
High quality wireless streaming
LDAC is a new audio technology from Sony that allows you to enjoy high quality wireless audio via Bluetooth®. With 3x the data transmitted, LDAC provides an enhanced wireless listening experience for all your music.
Seamless streaming with NFC and Bluetooth®
Near Field Communication (NFC) technology and Bluetooth® technology remove the need for wired connections and complex set-up. Simply touch your NFC-enabled device to the speaker for a quick, seamless connection, then start streaming your music collection. No NFC? No problem. Connect via Bluetooth® and you’re ready to go.
When you need to pause the party to take a call, use the speaker, not your phone. Make and answer calls wirelessly from your smartphone straight to your speaker with a built-in mic and Bluetooth® connectivity.
Charge your smartphone via the USB port
A smartphone, tablet, or Walkman® can be charged via USB connection, whether the SRS-X55 is running on battery or AC power.
Enjoy up to 10 hours' playback
Keep your music playing throughout the day. A built-in Li-ion battery delivers 10 hours of power.
Compact, wireless design
Listen at home, in the park, or on the move. Weighing 2.65 lb, the wireless SRS-X55's compact design is small and portable so you can take your music anywhere — without wires getting in the way.
Definitive Outline design
Smooth surface and clean lines ensure this sleek beauty blends into the background, yet still draws attention for its minimalist refinement. The accented perimeter is a signature of Definitive Outline.
