What Redditors Say
Best praise vs top criticism for FiiO BTR5
Best Praise
+6 pts“I personally don't notice any audible difference between my Shanling UA4 or BTR15 when it is in Bluetooth mode. What I do notice is how much more I use my IEMs due to reducing the friction of having something tethered to my phone. So my bias says if you can't hear a difference, and it makes using IEMs more convenient, I'd pick the BTR5 over the Dawn Pro nearly every time, I'd end up using my TWS that doesn't sound as good instead of I only had my UA4 out of sheer laziness.”
