Compact Bluetooth 5.4 speaker with IP67 rating

The Tecknet TK-BS004 is a portable Bluetooth speaker that fits in your hand and delivers stereo sound with a 2000 hertz response bandwidth. It connects wirelessly up to 35 feet using Bluetooth 5.4 and offers True Wireless Stereo pairing or Auracast for a wider soundstage. The IP67 waterproof and dustproof build suits poolside, beach or camping use.

Ideal for on-the-go listening.

This speaker suits anyone wanting a rugged, compact unit for travel, parties or outdoor gatherings where long battery life and easy mounting matter. The magnetic base and woven strap simplify placement on metal surfaces or hanging from gear. Buyers who need high-fidelity detail, deep sub-bass extension or multi-room Wi-Fi audio should look at other categories.

Up to 30 hours playtime at moderate volume

At 50 percent volume the battery lasts up to 30 hours; real-world tests show 20 plus hours at 70 percent and 11 plus hours at 90 percent. Bluetooth 5.4 provides a stable link within the 35 foot operating range. The active amplification handles casual listening and background music comfortably, while very large or noisy spaces will exceed its output capability.

Questions about this item

Do I need a device with Bluetooth 5.4 to use the TK-BS004 speaker?

The speaker connects via Bluetooth 5.4 and works within a 35-foot range; it pairs with any Bluetooth source that supports the same or earlier versions, so an older phone or laptop will still stream audio.

Can I run two TK-BS004 speakers together with my existing mono Bluetooth speaker?

True Wireless Stereo and Auracast pairing work only between two TK-BS004 units; a different mono speaker cannot join that stereo pair.

How do I know the TK-BS004 is delivering the 30-hour playtime after I charge it?

At 50% volume the rated life is 30 hours; real-world tests show 20+ hours at 70% volume and 11+ hours at 90%, so if your session lasts in that range the battery is performing as specified.
