Soundcore Select 4 Go portable speaker

The Soundcore Select 4 Go is a compact Bluetooth speaker built for outdoor use. It delivers 5W output through a single active driver with a 20 KHz response bandwidth and 85 decibels signal-to-noise ratio. An IP67 rating protects against dust and immersion up to 3.3 feet for 30 minutes, and the unit floats. A built-in strap and 9.3-ounce weight make it easy to carry on hikes, beach trips or around the home.

Upgrade from basic phone audio

Replacing a phone’s internal speaker adds 5W of amplified sound with wireless freedom up to 30 meters. The jump is worth it when you need louder, clearer audio that survives water, dust and drops. True Wireless Stereo pairing lets two units link for stereo separation, extending the soundstage without cables. Battery life reaches 20 hours on a single charge for all-day listening.

Suits outdoor listeners needing rugged portability

This speaker fits users who want a lightweight, waterproof companion for showers, camping, boating or poolside use. Buyers who need more than 5W output, longer than 20-hour playtime, or multi-speaker party modes beyond a stereo pair should look at larger models. It also does not suit installations requiring wired inputs or fixed mounting.

Questions about this item

What are the dimensions and weight I need to allow for when packing or mounting the A31X1 Select 4 Go?

The speaker measures 12.0 in x 8.2 in x 4.8 in and weighs 9.3 ounces, so it fits in a small bag or on a shower caddy without special brackets.

How do I pair two Select 4 Go speakers for stereo sound, and what step do people miss?

Connect the first speaker to your phone via Bluetooth, then press and hold the Bluetooth button on both units for 2 seconds to activate True Wireless Stereo pairing.

How long will the built-in battery last before it needs replacing, and what charging cycle does it support?

The battery delivers up to 20 hours of playback per charge; recharge via the USB port when depleted — no user-replaceable cell is provided.
