Portable Bluetooth 5.4 Speaker 20W

The dotn M17B is a portable Bluetooth 5.4 speaker delivering 20W stereo output with IPX7 waterproofing. It offers up to 20 hours of playback at 50% volume and supports True Wireless Stereo pairing for a wider soundstage. Built-in microphone enables hands-free calls while RGB lighting adds visual flair.

Upgrade From Older Bluetooth Speakers

This model replaces speakers limited to earlier Bluetooth versions with slower pairing and shorter range. The jump is worth it when you need 360-degree Hi-Fi stereo sound, DSP-enhanced clarity at high volume, and three EQ modes for tailored audio. TWS pairing doubles output for larger gatherings without extra wiring.

Suits Outdoor Listeners Needing Durability

Ideal for users who want a rugged, waterproof speaker for beach, poolside, or camping use with long battery life and versatile connectivity including TF card and AUX. Not suited for buyers who require multi-room Wi-Fi audio, voice-assistant integration, or a built-in power bank for charging other devices.

Questions about this item

What are the exact dimensions of the M17B speaker so I can check if it fits my bag or shelf?

The speaker measures 5.0 in by 5.0 in by 5.0 in, a compact cube that fits most cup holders and small bags.

How do I pair two M17B speakers for stereo sound, and what step do people often miss?

Turn on both units, then press the TWS button on one speaker to link them; the step often missed is waiting for the confirmation tone before playing audio.

The battery is sealed inside, so what maintenance will the M17B need over time?

Keep the Type-C port clean, rinse the IPX7-rated body with fresh water after salt or sand exposure, and recharge at least every three months during storage.
