Sanwa Supply introduces the 400-BTTWS8, an affordable true wireless earphone featuring active noise cancelling, Bluetooth 5.4, and up to 24 hours of playback, targeting commuters and active users seeking simplicity and durability.
Sanwa Supply has added a low-cost true wireless earphone to its line-up, pitching the 400-BTTWS8 at users who want basic noise control, modern connectivity and simple everyday durability without paying a premium. The model went on sale on August 12 through the company’s direct sales site, Sanwa Direct, with a listed pre-tax price of ¥3,618.
The key features are active noise cancelling and ambient sound mode, giving users a choice between reducing surrounding noise and letting outside sound in. In practical terms, that means the earphones are aimed at commuters, office workers and anyone who wants to switch quickly between focused listening and awareness of station announcements, shop counters or street traffic.
Sanwa Supply says the earphones support Bluetooth 5.4, which it says improves connection stability, latency and power efficiency. The company also claims that pairing is straightforward and that the earphones reconnect automatically when removed from the case. With the charging case included, total playback is rated at up to 24 hours.
The 400-BTTWS8 also carries an IPX4 splash-resistant rating, so it should cope with light rain and sweat during exercise. It ships with four sizes of ear tips, which should help users find a better seal and improve both comfort and passive isolation.
