Features:

Design & fit:

Improvement. A pure, sheer improvement over the 600. Big kudos to Hifiman. The TWS800 looks and feels great both in hand and in-ear. The metal face plate and metal accents near the nozzle compliment the matte black very well. The shape resembles that of custom in-ear monitors and offers an awesome fit.

- Built-in amp:

TWS800 added an independent amp to drive a fever headphone unit.

- Lightweight：6.9g

- Super rare earth magnet: guarantee of extremely high sensitivity.

- Nano coating.

- Topological diaphragm black technology:

High-frequency details go straight to 30kHz. Depositing nanomaterials on the surface of the diaphragm plays a role in changing the sound quality.

- Bluetooth 5.0.

- Ultra-low latency.

- 150Ω high impedance in-ear speaker unit, the source of power for low-frequency dominance.

- Bile taste tone:

The metal cavity brings a better frequency response and lower distortion.

- IPX4 waterproof.

- 31.5 hours endurance:

4.5 hours of uninterrupted listening, used with the charging box (the charging box can provide 6 additional full charges), and the battery life is up to 31.5 hours.

- 23dB Passive noise reduction.

- Ergonomic design, fitter and more comfortable:

The ergonomic appearance is developed using the large data of the ear canal size of the user's ear canal in the research and development of RE1000 custom earplugs.

- The charging box can hold an oversized silicone sleeve:

Most true wireless earphones cannot be charged normally when using a larger size silicone case. The TWS800 increases the internal space, and there is no need to repeatedly replace the silicone case when charging.

*8 pairs of silicone sleeves are included.
