FIIO FW5 REVIEW | Audiophilepure

In terms of signal latency, my Snapdragon 865-equipped phone running Android 13 experienced significantly less latency with the LHDC codec in the YouTube app compared to the AptX adaptive codec. I experienced similar results while playing games so if you are planning to game with the FW5 while using the AptX Adaptive codec, don’t. On Android, you’ll have to switch to LHDC or SBC for better latency performance, especially if you want to game using the FW5.

On iOS, the only available codec is as usual the AAC due to Apple’s limitations. I tested Disney+, Netflix & YouTube using 14PMX and the latency was good. I experienced mild latency with games though.
