The Boost Sync Wireless ANC Headset in black is a long-battery noise-cancelling headset for travellers, commuters and anyone who forgets to charge.
Battery is Sync’s headline. Boost rates it at up to 70 hours of music and 60 hours of talk time, with 300 hours on standby, so a full charge can last a week of commuting or a long trip up-country. Charging takes about 4 hours over USB Type-C. Noise cancellation is rated at 27 dB, stronger than the Beat or Reverb. Bluetooth 5.4 handles the wireless link, and an AUX cable is included for wired use on a flight or with an older PC. The 40 mm neodymium speakers and an IPX4 rating for sweat and splashes round it out. In black it stays understated in an office or on a plane.
