OWS headset: What is open wireless stereo? The True Wireless Stereo OWS Air Blaze headphones have ear hooks to ensure maximum stability even during training. OWS stands above all for open wireless stereo: unlike in-ear or semi-in-ear models, these open ear headphones do not fit into the ear canal. All this leads to longer listening to music or long calls without discomfort. In addition, you can also hear outside noise to avoid potential dangers. Thanks to the Hall Switch function, simply open the power housing and the headphones automatically connect to each other. Only the first time you need to connect it to your Android or iPhone phone. Discover all the other features in this short guide. TWS Long Battery Life Headphones The OWS Air Blaze headphones provide up to 7 hours of uninterrupted use on a single charge. The charging area provides 3 charges for a total of 21 hours of use when fully charged. Charging the base is very simple: there is a USB-C cable that allows you to connect it to a power source to power it. DUAL LEADER TECHNOLOGY: Use mono or stereo headsets Both headphones are equipped with a microphone: Dual Leader technology allows you to use only one while the other is charging. Take advantage of the benefits: When you wear one, you can hear outside noise or hear the driving voice of your navigation device, and double the battery life. These headphones cannot be separated when used individually. If you want to use them in pairs, you do not need to reconnect them. ENC Wireless Noise Cancelling Headphones Often hum and background noise make the call difficult. Thanks to ENC (Environmental Noise Cancellation) technology with TWS, background noise is suppressed. The voice of the interlocutor is returned clear and crystal clear so you can understand exactly what they are saying. Wireless headphones, splash-proof.
