Bluetooth Portable Subwoofer Waterproof Speaker with 360° Stereo Sound

Experience immersive audio anywhere with this Bluetooth portable subwoofer designed for 360-degree stereo sound and reliable outdoor performance. This waterproof speaker delivers deep bass and crystal-clear vocals via dual 52mm drivers, making it a functional companion for beach trips, poolside gatherings, or rugged adventures where wet conditions do not disrupt playback.

At the core of the audio system are dual 52mm loudspeakers rated at 4 Ω and 5 watts each. These drivers produce crisp highs and deep bass that fill available space, while the 360-degree sound design ensures consistent volume and tonal balance regardless of listener position. A high-sensitivity built-in microphone enables clear hands-free call answering without pausing music playback.

Hybrid connectivity sets this model apart from standard wireless speakers. In addition to Bluetooth streaming, the built-in card slot accepts TF storage cards and USB drives allow direct playback of digital music files without requiring a phone. Bluetooth 5.0 maintains stable links up to 10 meters, and dual-speaker pairing mode connects one iPhone, Android phone, or iPad to two units simultaneously for expanded 3D stereo imaging.

An integrated 1800mAh battery powers four to six hours of continuous listening on a full charge. Switching to call mode yields approximately six hours of talk time. Efficient standby logic preserves energy when idle, offering 30 days of standby time before the unit requires replenishment. A complete recharge cycle takes three hours via the provided cable.
