1. For parameters of Bluetooth 5.0, please refer Bluetooth SIG's official site: www.bluetooth.com
2. Please manually pair this item with your smartphone for first-time use. It will auto-reconnect to your phone in connectivity records if any.
3. Ultra-low latency gaming mode on. Triple tap right earbud.
Gaming mode will increase power consumption and reduce operation range. We do suggest you turn off the mode when not gaming.
Activating voice chat in gaming may result in a reduction of background sound quality, which cannot be fixed due to the limit of current Bluetooth technology.
Due to the limit of Bluetooth technology, Bluetooth earbuds suffer lag. Yet Airpods fix the issue through the integration of software and hardware. However, both Android and iOS systems at a budget price.
For any pairing device with Bluetooth 5.0 chipset, lag will be reduced largely. Otherwise, lag will remain, and signals will get weaker.
4. We measure the playback time in the following way. Fully charge Haylou T15 then keep playing music at 50% volume until it powers off. Practical playback time may vary from using situations.
5. Movie's length is recorded as 2 hours; one episode of drama 35 minutes; one track 4 minutes.
