User Tips
- Battery Life: The stated 6 hours of play time is an estimate. Actual battery life can vary significantly based on volume level and audio content. Playing at maximum volume will reduce the battery duration.
- True Stereo Sound: When using TWS (True Wireless Stereo) pairing with two Awei Y665 speakers, the sound will be split into distinct left and right channels, providing a more immersive stereo experience, rather than just duplicating mono sound.
- Outdoor Use: Thanks to its IPX7 water repellency and anti-shock design, the speaker is well-suited for outdoor environments. Just ensure the port cover is sealed.
