I have just one earphone that's 2 pin (the Truthear x Crinacle Zero) and that's my daily driver especially for my usecase (i.e., gaming), it's 0.78 so it won't cause any compatibility issues with the tws module.

But my problem is so weird, I usually get downvoted to hell for this.

Pro's of the UTSW5:

• it supports Aptx Adaptive so I don't need to buy a transmitter for low latency on my phone (phone has aptx adaptive) I need this coz I like to play mobile fps shooters (rip apexM)

• TWS, convenience (helps me hide that I'm a boomer, audio snob)

Pro's of BTR5

• Repairability: this is huge for me as the price of both is way too much for me, it won't turn into e-waste after the battery dies.

• Codec: Although my phone doesn't have Aptx LL, if I buy an aptx ll transmitter it will be far superior to the above aptx adaptive setup, which is slower. Although it's just 20-40ms difference, it's a lot noticable in shooting games

TLDR: codecs and repairability
