Ortizan Portable Bluetooth Speaker, 40W Powerful Sound and Deep Bass, IPX7 Waterproof Wireless Speaker Music Box with Colorful Lights, TF/AUX in Play

With extended use, users notice that the battery lasts 12 to 15 hours even at maximum volume, which is reliable. The speaker is heavier and solidly built, with firm buttons that some perceive as a sign of quality. Several buyers tested it in water and confirmed it is moisture-resistant. The equalizer works without issues, and the LED lighting can be turned off. Bluetooth 5.3 connectivity is stable, and pairing two speakers in TWS mode is simple and automatic.

Complaints are minimal. Some noticed that with deep bass in genres like techno or R&B, the bass needs to be lowered to prevent the sound from becoming too loud. One buyer would have appreciated a stand for horizontal placement. Buttons require firmer pressing. Without an app for settings, everything is controlled via physical buttons. The speaker is smaller than some expected, but this does not affect sound quality.
