Ultra-Light In-Ear Design

Each earbud weighs 3.7 grams and uses an ergonomic shape made for small ears. The low-profile fit stays secure during workouts and remains comfortable when sleeping on your side. No hard edges press against the ear during extended wear.

Battery Life and Stable Connection

Bluetooth 5.3 delivers fast pairing and reduced dropouts while moving around home or office. A single charge provides up to 7 hours of playtime and the case extends total listening to 32 hours. LED indicators on the case show remaining power at a glance.

App Setup and Fit Limitations

The TOZO app supplies 32 EQ presets for bass, vocal or balanced tuning. Ear coupling is single-ear only, so stereo separation depends on both buds fitting correctly. Buyers who need active noise cancellation or multi-point pairing should look elsewhere.

Questions about this item

Will the earbuds and case stay cool after 7 hours of continuous use?

The 3.7 g earbuds and 35.1 g case use low-power Bluetooth 5.3 and have no active cooling, so they remain near ambient temperature during a full 7-hour session.

What must I already own to use the 32 EQ presets and firmware updates?

A smartphone or tablet running the TOZO app is required to access the 32 EQ presets and any firmware updates.

Will the earbuds pair instantly with a laptop that only has Bluetooth 5.3?

Yes, Bluetooth 5.3 provides fast pairing and a stable connection with any device that supports the same version.
