Frequently Asked Questions

TOZO integrates proprietary OrigX acoustic tuning algorithms, Hi-Res Audio certification, and high-bitrate LDAC codec support across its premium lineup. This architecture enables uncompressed Bluetooth audio transmission at up to 990 kbps—roughly three times the data capacity of conventional SBC codecs.

Furthermore, TOZO hybrid Active Noise Cancellation (ANC) utilizes paired feedforward and feedback microphone arrays to silence ambient low-frequency sound by up to -52dB, while ENC multi-microphone calling technology filters environmental noise for crystal-clear voice clarity during business communications.

Each form factor is engineered for specific operational environments and ergonomics:

1. In-Ear Earbuds: Form airtight silicone canal seals for maximum passive noise isolation, deep dynamic bass response, and compact portability during travel and daily commutes.

2. Open-Ear Audio: Incorporates directional air-conduction acoustics and light clip-on ear-ring structures (weighing as little as 5.1g per earbud). They sit outside the ear canal, mitigating acoustic pressure while allowing 100% ambient situational awareness for outdoor running, cycling, and collaborative office spaces.

3. Over-Ear Headphones: Feature large 40mm titanium-plated dynamic drivers, plush memory foam earcups, low-latency gaming/video modes (78ms response), and massive battery chambers delivering up to 80 hours of continuous playback.

Yes. Popular sports models such as the TOZO T6 and T10 series feature structural IPX8 waterproof engineering combined with internal hydrophobic nano-coating. This protective shield resists water immersion deeper than 1 meter for 30 minutes, preventing sweat corroding internal PCB circuitry during intense physical training or outdoor rain exposure.

Yes. TOZO true wireless earbuds feature master-slave switching technology. Either the left or right earbud can function independently for calls or music while the other recharges inside the magnetic battery case, extending overall operational time for workplace tasks.

The TOZO mobile App enables precision custom EQ adjustments, pre-set equalizer modes (Jazz, Bass Boost, Classical, Vocal), active noise cancellation intensity toggling, touch-control remapping, and over-the-air (OTA) firmware enhancements to maintain peak acoustic delivery.
