TOZO A1 Ultra-Light In-Ear Earbuds

The TOZO A1 are true-wireless in-ear headphones weighing 3.7 grams per earbud and finished in black. They use Bluetooth 5.3 for stable pairing and carry an IPX5 waterproof rating for sweat and light rain. The charging case extends total listening time to 32 hours, while the TOZO app provides 32 EQ presets for sound personalisation. Two built-in microphones with ENC AI processing reduce background noise during calls.

Ideal for commuters and active users needing

The compact, ergonomic shape suits small ears and stays secure during workouts or side-sleeping. The 32-hour case life covers long journeys without a recharge. Buyers who require active noise cancellation should look elsewhere, as the A1 relies on passive isolation only. Listeners wanting over-ear comfort or a wired connection option will not find those features here.

Simple pairing and app setup

Open the case near your phone to enter pairing mode, then select TOZO A1 in Bluetooth settings. Download the TOZO app to unlock the 32 EQ presets and firmware updates. The touch controls can trigger accidentally when adjusting the fit, and the single-ear coupling means mono use is possible but stereo imaging is lost. Ensure the ear tips seal properly or bass response will drop noticeably.

Questions about this item

Does my phone need to support Bluetooth 5.3 for the TOZO A1 earbuds to pair?

The earbuds use Bluetooth 5.3 and will pair with any phone or tablet that supports Bluetooth, including older versions; the connection simply falls back to the highest version both devices share.

Will the 32 EQ presets in the TOZO app still work if I keep using an older phone that cannot install the latest app version?

The presets are stored in the app, so they require a phone that can run the current TOZO app; if the older phone cannot update the app, the presets will not be available.

How can I confirm the earbuds are delivering the advertised 102 dB sensitivity and 20 Hz low-frequency response after setup?

Play a bass-heavy track at a moderate volume; you should hear clean output down to the lowest notes without distortion, and the LED indicators on the case will show charging status to verify power delivery.
