Lindy's LH700XW are closed-back headphones, offering uncompromised audio quality with a wireless or wired connection for listening to music, podcasts, movies or games. The LH700XW's Bluetooth® connectivity, comfortable protein leather ear cushions and lightweight, adjustable design provide convenient wireless listening while traveling, working out or at work. Hybrid Noise Cancellation ensures that up to 98% of external ambient noise is cancelled, using both external (feedforward) and internal (feedback) microphones for noise detection. This provides a quiet hearing experience ideal for workplaces with high ambient noise levels or on public transport. The LH700XW's controls provide seamless, easy playback control - play, pause and skip tracks, as well as volume control. The built-in microphone also allows wireless use for phone or video calls, with the controls also providing call control. Twin pairing also allows two Bluetooth® devices to be connected simultaneously, ideal for easily switching between music from a laptop and a call from a connected smartphone, for example. The built-in rechargeable battery recharges quickly at approximately 3 - 4 hours for a full charge, and provides consistent performance over extended periods of time with up to 50 hours of wireless playback. An included 3.5mm cable also allows for wired use, with which ANC can also be used.
