NOTE 1. For non-aptX LL supported headphones/speakers (e.g. Bose, Beats, Sony headphones), B26 will work with them using SBC or aptX codec with 70-200ms latency - Lip-sync delay could be noticed by sensitive users. 2. Operation range can be affected by Wi-Fi routers, Wireless TV adapters, physical obstructions like walls, metal obstacles etc. and also depends on receiving device. 3.
