The key difference from standard Bluetooth earbuds is the option to play files stored on the headphones. Bluetooth cannot connect underwater, so MP3 mode is the practical choice for swimming. Above water, wireless Bluetooth lets you connect to a cell phone, while the open-ear fit helps keep surrounding sounds audible. A built-in microphone supports calls, and the Boean app offers adjustable EQ, AI music composition, sleep audio, real-time translation, and speech transcription.
Practical tips
Before a swim, connect the headphones to a computer and copy compatible audio files to the built-in storage. Once powered on, double-click the power button to select MP3 mode, the headphones start in Bluetooth mode by default. Saving music in advance lets you listen without carrying a phone or depending on an underwater wireless connection. For workouts on land, use Bluetooth with a connected phone instead.
The open-ear design uses bone conduction drivers and soft silicone cushions at the front of the ears. An adjustable strap is included to accommodate different head sizes and help keep the headphones in place during activity. For charging, connect the magnetic charging cable, the stated full-charge time is about two hours. The headphones are rated for underwater use up to 2 meters deep for one hour.
Buyers commonly praise the sound, battery life, and reliability. Those impressions offer a sense of what owners value, while actual listening and battery experience can vary with use.
