Headphones — Tanchjim Rita

The Rita is a Bluetooth headphone, closed-back and worn over the ear, made by the Chinese firm Tanchjim, which is better known for in-ear models such as the Lost Manor and Zero Ultima. On the company's own product menu it is the only over-ear design. It was announced on 7 February 2026 with a list price of USD 89.99 or EUR 89.99, and 12,800 yen in Japan, and the model surfaced in FCC filings before launch.

Key specs that matter

Tanchjim fits a 40 mm dynamic driver labelled DMT 5, whose PET diaphragm carries a beryllium coating, and the driver sits in front of an independent rear acoustic chamber. Tanchjim quotes a range of 20 Hz to 20,000 Hz, an impedance of 32 ohm and harmonic distortion of 0.039 percent at 1 kHz and 94 dB. The 650 mAh cell, rated at 2.405 Wh, gives up to 92 hours of playback with noise cancelling switched off and 51.5 hours with it active. Charging runs through USB-C at 5 V and 1 A. The radio uses Bluetooth 6.0 with SBC, AAC and LDAC codecs and covers up to 15 metres in open space, transmitting at 20 dBm EIRP in the 2400 to 2483.5 MHz band.

Engineering and use context

Active noise reduction uses a hybrid scheme with a dual-feedback architecture, and four microphones monitor sound both outside and inside the cups. Tanchjim claims a maximum reduction of up to 47 dB. Beyond wireless use, a 3.5 mm input accepts a cable, so the Rita can still play when its battery is flat or when a wired source is preferred. A companion app handles EQ adjustment and a set of DSP profiles. The earpads are soft synthetic leather over dense foam, and the headband is metal with a multi-motion hinge that lets the cups follow the shape of the head. The long battery rating means a full week of commuting and office use is achievable between charges, while the noise cancelling time still covers several long-haul flights.

Pairing

LDAC support makes an Android phone or a digital audio player with that codec the natural partner for high-bitrate streaming, while iPhones and Macs will connect using AAC. For home use a desktop DAC and headphone amplifier can drive the wired input, and the modest impedance places little demand on nearly every headphone socket, including the jack on a laptop.

Alternatives

Tanchjim has no other over-ear model, so its closest headphone is the Lost Manor, a wired in-ear monitor.
