Earbuds / Case Ratings

Stay aware with open-ear listening

The ear-hook design leaves the ear canal open, so you can hear nearby activity while enjoying audio. A reflective neck strap helps keep the earbuds together during movement.

Choose your wireless connection

Use SpeedNova 2.4 GHz for supported gaming devices or Bluetooth for compatible everyday devices. Gear Link provides audio and device settings. Match the actual host, connection and selected operating mode, then check the result with the equipment and settings you intend to use for the session.

Understand the 64-hour rating

Up to 16 hours from the earbuds plus 48 hours from the case gives a maximum of 64 hours. This rating uses Bluetooth with the microphone muted, RGB off and onboard audio modes disabled; actual use varies.

Voice clarity and audio modes

The quad-microphone system uses AI noise reduction for calls. Phantom Bass adjusts perceived low end, while Immersion Mode reduces steady background rumble without creating a sealed-ear fit.

Ready for everyday movement

The earbuds carry an IPX5 rating; the charging case is IPX2. These are splash-resistance ratings, not permission to submerge the product. Match the actual host, connection and selected operating mode, then check the result with the equipment and settings you intend to use for the session.

What should I check for this exact model?

Cetra Open Wireless leaves the ear canals open. The up-to-64-hour total is 16 hours from the earbuds plus 48 from the case, measured using Bluetooth with the microphone muted, RGB off and onboard audio modes disabled. AI call noise reduction is separate from a sealed-ear listening experience.

Do the battery figures apply to every setting?

The 64-hour maximum includes charging-case reserve and uses the stated Bluetooth test with microphone muted, RGB off and audio modes disabled. Wireless mode, calls, volume and other settings change actual runtime.

Are the charging case and earbuds safe to submerge?

The earbuds are IPX5 and the case IPX2. These are resistance ratings for specified conditions, not submersion ratings; follow the manufacturer’s care and charging instructions.

How should I choose the connection for a game?

Check the exact device, platform edition and wireless mode supported by the host. Use the intended gaming receiver where appropriate, and confirm the selected game and chat inputs rather than assuming Bluetooth and 2.4 GHz behave identically.
