OYIB K9 portable Bluetooth speaker

The OYIB K9 is a compact Bluetooth speaker designed for listeners who want music in wet or outdoor environments. Its IPX7 rating and integrated suction cup let it attach securely to smooth surfaces such as shower walls or poolside glass. RGB LEDs pulse with the beat, adding visual flair to casual gatherings or travel.

Sustained playback and stereo pairing

A lithium polymer battery delivers 7 to 8 hours of continuous playback from a 1.5 hour charge, supporting extended sessions without frequent recharging. True Wireless Stereo allows two K9 units to link wirelessly, forming left and right channels for a wider 360° sound field during longer listening periods.

IPX7 waterproof rating

The IPX7 certification is the single specification that determines whether this speaker survives immersion in water up to one metre deep. Buyers who need a speaker that can be submerged or sprayed directly should verify this rating meets their requirements. Those requiring longer battery life or larger driver output will need a different device.

Questions about this item

How much heat or noise does the OYIB K9 produce when running all day?

What must I already own to use the K9 speaker?

You need a Bluetooth-enabled phone, tablet or computer to stream audio, plus a USB power source for the 1.5 h recharge.

Will the K9 work alongside my older non-Bluetooth stereo?
