Wireless Bluetooth in-ear headphones for mobile devices from Byron series that combine great sound with high-quality workmanship and ease of use. Both music and phone calls are transmitted via Bluetooth, which provides complete flexibility with the usual excellent sound. All playback devices can utilise their sound potential fully thanks to the use of Qualcomm aptX and AAC codecs, ensuring top-quality Bluetooth transmission. The acoustic transducers for right and left ear are connected to one another simply by means of a short cable – tangled headphone cables are therefore a thing of the past. These headphones come with replaceable silicone ear tips in three sizes. Two ear hooks are also included as bundled accessories for active wearing. The silicone loops are assembled in addition to the normal attachments and nestle into the ear shell while wearing. The earphones thus always fit perfectly into the auditory canal. A high-performance rechargeable battery supplies the headsets with energy for up to 7.5 hours. A voice prompt informs user of the current charge level. Any USB port can be used for charging, for example using a smartphone charger or laptop. The appropriate charging cable is included and fully charges the battery within two hours. The headphones are equipped with a 3-button remote control and a hands-free microphone for use on Apple and Android devices. Thanks to the integrated hands-free microphone, not only can the headset be used for listening to music but also for phone calls on all popular smartphones. A soft case and operating instructions are included. Frequency response: 10 Hz-23 kHz. Nominal SPL: 90 dB.
