1. Many headphones / speakers are primarily for music, not watching TV and do not support aptX-LL. The JH-201D will connect with these devices using another codec (e.g. SBC, aptX), resulting in a 70-200ms audio delay which may be noticeable by some users. To achieve low latency, your device also has to support aptX Low Latency. For example, you may check SIMOLIO receiver JH-211D or headphone JH-716B etc.
2. SIMOLIO JH-201D is not a Bluetooth receiver, does NOT support being paired with any phone.
3. Online calls and video chats are available when SIMOLIO is transmitting with USB connection to PC or laptop.
