Immerse and let music motivate

  • Sensitive φ 6 mm (1/4˝ ) rare-earth-magnet drivers and the AAC codec via Bluetooth® 5.0 wireless technology bring the bass punch and dynamic energy you need to immerse, focus, and stay in the zone when exercising.
  • Ear Direct Mount Structure avoids sound-damping issues by aiming the drivers directly into the inner ear, making music an internal force that pushes you forward.

Avoid vehicles you can’t see

  • Ambient awareness earphone tips have thin slits that are uniquely designed to allow a certain amount of external sound in, so you can stay aware of your surroundings and avoid bikes or cars that approach unexpectedly when you’re jogging.

Hear announcements at the touch of a button

  • Ambient Awareness Mode connects you to the outside world at moments when you need to hear an announcement, such as on public transport.
  • With a tap on the left earphone button, the mic turns on and captures outside sound while audio volume is attenuated soyou can hear clearly.
    Note: When Ambient Awareness Mode is ON, noise may occur when touching earphones since external sound is collected with built-in mic.

Excellent stability for workouts

  • Secure ear fins supplied in S/M/L sizes assure a perfect fit for your ear size. The fins fit over the auricle and keep the earphones in place, and are ideal for aerobic exercise. Athletes wanting extra peace of mind can attach the supplied leash to the earphones, preventing loss should one come free.

Marathon 5-hour playtime leads the class

  • The E9truly wireless leads the field with fivehour wireless playback, enough to play music for the typical duration of a marathon for the average distance runner—or to cover your commute each way to work or school.
  • You can recharge three times on the go via the carry case, extending total listening time to about 20 hours, or use Fast Charge for an hour’s playback in just 15 minutes.
  • The E9truly wireless earphones power up and enter pairing mode automatically when removed from their carry case.

  • The E9truly wireless is among the few wireless earphones to feature both IPX5 and IPX7 certification.
  • The earphones are water-resistant and washable*. Continue enjoying your music as you run in the rain, and wash off the sweat when you’ve finished your workout.
