What the C16 earbuds deliver
The SuperTooth C16 true-wireless earbuds use Bluetooth 5.4 to provide up to 60 hours of total playback from the charging case. Each bud runs for up to 15 hours on a single charge and supports touch controls for music and calls. They are built for listeners who want long battery life and clear voice pickup without a neckband or cable.
Bluetooth 5.4 practical limits
The earbuds implement Bluetooth 5.4 with HFP, A2DP, HSP and AVRCP profiles for stereo audio and hands-free calls. Compared with Bluetooth 5.3 the link offers 45 percent lower power draw and 35 ms less latency while maintaining a stable range of 50 feet. Devices that only support older Bluetooth revisions will fall back to those versions and lose the efficiency gains.
Build, IP7 rating and charging case
The buds carry an IP7 waterproof rating so they survive heavy sweat and rain during workouts. A dual LED display on the case shows the remaining percentage from 1 to 100 while charging. The case recharges over USB-C and a 10-minute top-up adds roughly 2 hours of playtime. Earhooks keep each bud secure during vigorous movement.

Questions about this item
Should I pick the C16 earbuds for 60 hours total playtime or rely on the 15-hour single-charge claim?
The charging case delivers 60 hours combined; each earbud runs 8 hours per charge and the case adds six full recharges, so the 15-hour single-charge figure does not apply to this model.
What does the 14.2 mm graphene driver and 18 Hz–25 kHz range mean for daily listening?
The larger driver and extended frequency response produce deeper bass and clearer treble, giving more detail in music and clearer voices on calls.
How does Bluetooth 5.4 change the connection compared with Bluetooth 5.3?
Bluetooth 5.4 cuts power use by 45 % and latency by 35 ms while keeping a stable link up to 50 feet, so audio stays in sync and the battery lasts longer.
