Brise Audio Tsuranagi new portable headphone amplifier from Japan

Japanese company Brise Audio unveiled its Tsuranagi portable headphone amplifier, announced back in the spring of 2021. In Japan, the Brise Audio Tsuranagi can be purchased at a price of 297,000 yen (about $2500). It can be supplemented with a proprietary balanced cable. In this case, the amplifier will cost 330,000 yen (about $2800).

TBrise Audio Tsuranagi headphone amplifier received two inputs (standard 3.5mm and balanced 4.4mm) and two outputs (2.5 and 4.4mm – both balanced). The device is capable of delivering 2×1000mW with a 32Ohm headphone impedance. The frequency range is 2 – 20,000Hz. A full battery charge lasts up to 8 hours.

The manufacturer notes that the new amplifier is manufactured exclusively in Japan, while due to the lack of semiconductors, the supply of the new amplifier may be delayed.

At first glance, it may seem that devices of this size and class have a rather high price, it is difficult to name competitors in this price category right away. However, Brise Audio assures that “TSURANAGI is designed with the guiding principle of minimizing the influence of the external environment and bringing out the best performance of the equipment as much as possible in terms of sound quality and performance“.
