I am very sad to say this but TRN BT20S Pro is not a good buy. Unfortunately these have some kind of flaw that makes them create constant white noise and distortion with or without music playing. The distortion fades in getting louder then fades out again. The parts that do work as intended are the play controls, automatic on\off, easy pairing, and the secure fit of the earpiece, however these features are overshadowed by the unwanted distortion.
The Bluetooth connection is the only positive element. When attached to larger IEMs, the modules sometimes disconnect from the case when closed. The big issue is the left module. The left module has a large amount of hiss that strangely increase with load. The hiss only goes away when there is sound from the full frequency range at an uncomfortable volume. This hiss makes most music unlistenable. The sound from the right side is "good enough". An annoying thin is that the USB C port is moderately deep which make it difficult to use some cables.
Got these new & sealed from eBay. Right side came broken out of the box. Does not turn on, does not charge. I'm afraid there is no quality control at all.
So I ordered a 0.75mm hook for my trn pro and ordered extra mmcx one. What came is both mmcx! Please refund me the additional money I paid for the extra hook!

I got the BT20s pro for work. I work in a steel mill on the rolling floor, lots of noise, but no real need to communicate with others(solo job). I can have music instead of earplugs, but no wires(safety hazard). Using my fiio fa1 with these.
I’ve had every iteration of the BT20 series and this is by far the best of the bunch by a long shot. It’s more comfortable in the fit with the ear hooks being softer and more pliable. The built in amp drives better at lower volumes (where I’d have to be at 80 to 90 percent volume on the BT20 I only need to be at 40 to 50 on the pro) the charging solution is a million times better and more convenient. I’ve tried the case with a pair of BLON 03s ZS10 pros and Legacy 3s and all of them fit perfectly while connected to the hooks. This changes once you try to add a wire in the case as well but it can still fit if you disconnect the items and sit them flush in the case. They connect pretty much the same as previous versions on first pairing but after that they auto connect as soon as you take them out the case. And the shut off as soon as you put them back in the case. The convenience and improved driving capabilities alone make it worth the upgrade to me.
Only complaint I have at the moment is that you STILL can’t control volume on the headset and having replaceable ear hooks only makes sense if you can buy them separately . It’s not going to give you better sound quality than an es100 or BTR5 but this is for those times that you want better than typical crap TWS sound quality but can’t or don’t want to fiddle with wires of any kind. This is my go to for work listening.
