Ultra-portable Bluetooth speaker for outdoor use

The Soundcore Select 4 Go A31X1 is a compact active speaker rated at 5 watts with a 1.0 channel configuration. It connects via Bluetooth to smartphones, tablets, laptops and desktops within a 30-metre operating range. Weighing 9.3 ounces and measuring 8.2 by 12.0 by 4.8 inches, it includes a strap for easy carrying during travel, camping or home use.

IP67 waterproof and dustproof design sustains

The enclosure meets IP67 protection, meaning it resists dust ingress and survives immersion in water up to 3.3 feet deep for 30 minutes. The speaker also floats, so it remains retrievable if dropped in a pool, lake or bathtub. This rugged build supports continuous playback through showers, beach picnics or sailing trips without degradation from moisture or grit.

20-hour battery life defines all-day autonomy

A single charge delivers up to 20 hours of playback, covering extended outdoor gatherings or multi-day excursions without recharging. True Wireless Stereo pairing allows two units to link for stereo separation when wider sound is needed. The 5-watt output and 85-decibel signal-to-noise ratio provide clear, punchy audio for personal or small-group listening.

Questions about this item

Does the 5W output run hot or drain the battery quickly during a full-day hike?

The 5W active speaker delivers up to 20 hours of playback on one charge, so it lasts through an all-day hike without overheating or needing a recharge.

What device do I need to start playing music on this Bluetooth speaker?

Any Bluetooth-enabled smartphone, tablet, MP3 player, laptop or desktop within the 30-metre operating range will connect and stream audio immediately.

Can I pair this Select 4 Go with an older Soundcore speaker that only supports PartyCast?

This model uses True Wireless Stereo pairing; it connects only with another Select 4 Go or TWS-compatible speaker, not with PartyCast-only units.
