Crank up the music and the lights wherever you like with Sony’s SRS-XB21 wireless speaker, packing Extra Bass tech to provide more kick to your grooves. Entirely portable thanks to Bluetooth and NFC connections and a rechargeable battery, it’s the perfect companion to take the party with you, complete with synchronised lighting! By using the Sony Music Center App on your smart device (iOS and Android), you can engage Live Sound Mode for a festival vibe, and even join in by tapping the speaker to add drum hits and sound effects. IP67 rating water, dust and rust resistance means worry-free transportation and the club atmosphere keeps pumping wherever you want to take it.
Music & Lights
The SRS-XB21 packs dynamic audio punch with a frequency range of 20-20,000 Hz for clear and powerful sound delivery. An LED multi-coloured light ring around the speaker grille illuminates in unison with the beats for the ultimate portable party. So you can dance in the light with the music playing loud.
Extra Bass
Tailor-made for dance music and heavy grooves, Sony includes its Extra Bass technology. A 42mm full range speaker reaches deeper bass, and a rigid and light speaker cone ensures it maintains punch and clarity.
Live Sound Mode & Party Booster via the Sony App
Using the Sony Music Center App (available on iOS and Android) you can play DJ, controlling tracks and lighting, all from the convenience of your smart device. The speakers in the XB21 are specially aligned to create a three-dimensional sound experience. Engaging Live Sound Mode via the app, it throws your music out to a wider area and creates a live, festival vibe. And you can join in with the music like never before with Party Booster. Tap the speaker for additional sound effects, like scratch effect or drum sounds. Tap harder for louder sounds and get everyone joining in.
Bluetooth & NFC
It’s a doddle to stream your top tracks wirelessly to the SRS-XB21 with Bluetooth and NFC connectivity. Simply pair your phone or tablet to the speaker (one touch connection with NFC) and let the music flow. LDAC technology ensures a superior listening experience to conventional Bluetooth.
Battery Powered Freedom
Small and compact but packing a mighty punch, the SRS-XB21 can go anywhere with you and lasts as long as the party does. A full charge gives you up to 12 hours of listening pleasure.
Take Anywhere
The XB21 is tough and durable enough to be used by the pool, in the park or by the beach. With an IP67 rating it can be immersed in water up to 1 metre deep for up to 30 minutes, is cleaned easily, and is dust-proof and rust-proof too.
Wireless Party
With Wireless Party Chain you can connect up to 100 compatible Sony speakers in the series via Bluetooth, synchronising music and lights for an extended danceathon. Or just pair two together to feel the music in super stereo.
