FAQ
Questions, answered.
How bone conduction sounds, what IP68 really allows, how long the battery lasts, and how ordering works.
Sound & technology
Sound travels through your cheekbone straight to the inner ear, so it feels like it comes from inside your head rather than from a speaker. Vocals and mids are crisp and clear; deep sub-bass is gentler than in-ear headphones because your ear canal stays open. Most people adapt within a single session and never go back.
At low and medium volume, effectively no. Above roughly 80% volume a faint amount of sound escapes, similar to open-back headphones. In a quiet office, keep the volume in the mid range.
Nothing enters the ear canal, so there is no pressure, no trapped moisture and far less irritation on long sessions. Volume still matters — extended listening at maximum level is not recommended with any headphone.
The capsule rotates through 15° so you can place it exactly on the cheekbone contact point that transmits best for your anatomy. A small adjustment noticeably increases clarity and perceived bass.
Water & sport
Yes. IP68 is the top of the ingress protection scale — sealed against dust and rated for submersion. Because Bluetooth does not travel through water, switch to onboard storage playback before you get in the pool.
The titanium alloy memory band wraps behind the head and holds firm through sprints, burpees, rowing and jumps. At 32 grams the headphone stops registering after the first few minutes.
Rinse with fresh water, wipe with a soft cloth and let the contacts dry fully before placing the headphone on the magnetic charger.
Battery & connectivity
The 180mAh cell delivers 8–12 hours of playback depending on volume and mode. A full charge takes about 2 hours on the magnetic dock, and a 10-minute top-up returns up to 1 hour of listening.
There is no open port to let water or dust in — a requirement for an IP68 seal. The contacts snap into position and hold while charging.
Bluetooth 5.0 on the JL7006 / JL7018 platform holds a stable link beyond 10 metres in open space, with LE Audio support and NFC tap-to-pair on compatible phones.
8GB holds roughly 2,000 tracks and 32GB roughly 8,000. Connect the headphone to a computer with the magnetic cable and drag files across.
Orders & aftercare
KES910-Plus is the all-round flagship. KES958-Plus is tuned for swimmers who lean on onboard storage. KES988-Plus is the long-session choice for cycling, gaming and everyday wear. The Compare page lays the three side by side.
