Need music for a beach day, campsite, or time at home? The rechargeable battery, IPX7 waterproof rating, and portable format make it easy to bring along.

Benefits

Dual 60mm full-range drivers and digital signal processing are designed to deliver clear highs, balanced mids, and deep bass in a stereo setup. With 30 watts of maximum output power, the S11-3 brings a substantial sound setup into a compact speaker format. Its BASS 3.0 system is designed to emphasize low frequencies, so playlists with a strong beat retain a fuller bass presence.

Bluetooth 5.4 provides a wireless connection, and the speaker also supports SD card and AUX playback. That flexibility is useful when you want to switch between streaming from a phone and playing audio from another source. For a wider stereo presentation, pair two compatible S11-3 speakers using TWS.

Eight RGB lighting modes add color while music plays, making the speaker a practical choice for casual gatherings as well as everyday listening. Its IPX7 waterproof rating and portable design suit outdoor plans such as camping, hiking, or a beach trip.

Worth noting

The 4,000mAh rechargeable battery is rated for up to 24 hours of playback at 30% volume with the lights off. Charging takes about 3 hours. Battery life will depend on how the speaker is used, and the stated playback figure is tied to those settings.

The speaker has a built-in microphone for talk time, push-button controls, and a 30-watt maximum output. In comparison with a speaker limited to Bluetooth playback, the S11-3 gives you SD card and AUX options too, which can be useful when you want to choose a different audio source. Its compact dimensions also make it easier to carry than a larger stationary speaker.

Tips for day-to-day use

For a simple listening setup, connect a phone or tablet over Bluetooth and use the push buttons to control the speaker. Choose an SD card or AUX connection when that better suits your audio source. If you want sound from two speakers, use TWS pairing. For longer playback, the stated 24-hour figure applies with the lights off and volume at 30%, charging takes about 3 hours.

What to clarify

What connection options does the speaker support? It supports Bluetooth 5.4, SD card playback, and an AUX connection, giving you several ways to play audio.

Can I use two S11-3 speakers together? Yes. TWS pairing lets you pair two wireless speakers for a stereo listening setup.

How long does the battery last? It is rated for up to 24 hours at 30% volume with the lights off. The battery is rechargeable, and charging takes about 3 hours.

Final verdict

A solid pick if you want a portable speaker that combines stereo drivers, bass-focused audio, and several playback options in one compact unit. The IPX7 rating suits outdoor plans, while TWS pairing and RGB modes add useful flexibility for listening at home or sharing music on a trip.
