Q: How to improve the stereo streaming effectiveness?
A: Please try the following instructions under the typical conditions:
1. Bluetooth Bandwidth Limitation - The i-PHONO PLUS headphone uses
Bluetooth wireless technology to communicate that requires full bandwidth
to stream stereo wirelessly. The stereo wireless streaming may be
interrupted or interfered if another Bluetooth device is connected
simultaneously with the A2DP-Source device such as a computer or PDA.
Only connect the headphone with the computer can keep the stereo
streaming quality.
2. RF Interference - The radio noise may be caused by the nearby device such
as a Wi-Fi device, microwave oven or cellular phone station, and the radio
noise may interfere with the stereo wireless transmission. Please place the
A2DP-Source device to be closer to the headphone.
3. Environment Obstruction - If the headphone is distant from the
A2DP-Source device, or if there are some metal obstructions in-between,
the stereo wireless transmission may be interdicted. Please move the
A2DP-Source device from the possible metal framework, shelf or container,
and place it in the wider area.
Q: Why the Bluetooth connection is unable to be switched back to
the music player (A2DP) after I ended a phone call?
A: The connection switching duration will be longer for some phone model,
please wait the whole process is completed. Moreover, some mobile phone
models may not release the Bluetooth connection automatically will cause the
headphone to fail to switch the connection from the HSP / HFP (mobile phone)
to the A2DP (music player). Please turn off the Bluetooth radio of your mobile
phone in advance if you meet the issue, and then restart the headphone.
