Fanmusic TRN BT20 Pro True Wireless Bluetooth 5.3 Earphone Module Swappable connectors (Headphones not Included) (2Pin 0.78mm)

First off, dang the charging case if huge! I've gotten the MMCX version instead of the 2 pin just because I have an MMCX to 2 pin adapters and some people claim that the 2 pin version is not up to standard... I use these with the Zero:Blue2 iem and, for what it is, is a nice addition for anyone who wants to turn their wired iems to earpods. The sound quality of these aren't the best but, depending on your iem, with the zero:blue2 it does retain the bass. However the sound seems more quiet compared to if you use a wire cable. The ear hooks fits comfortably around the ears and with the adapters making it a bit longer, is still comfortable to wear. Going to far away from the connected DAP or device will cause the bluetooth connectivity to fluctuate and in and out trying to stay connected. Making the music fade in and out with both earpiece. There are alot of these bluetooth hook adapters for iem that ranges from 29 usd (maybe 25 usd at the least) to over 100+ usd (Fiio) out there. These ones I like for its price range and the fact I took a dive with tis one instead of the others! Just make sure to remove the plastic film from behind to ear hooks in order to charge them.

Very light, and for the hour (or so) I've been using them, they seem very comfortable (I barely feel them at all). As you can see in the attached photos, I wear glasses, and the BT adapters don't press the arms into my head, which was something I was nervous about (I really didn't want to have to return these in that case). I had zero issue getting these paired to my phone - As soon as I long-pressed the button on one of them, they showed up in my phone "Connected Devices" list, and paired without issue. I'm happy that the BT adapters, IEMs, and the foam tips all fit into the case -- every pair of ear buds I've had over the years could not fit the foam tips I use into their cases. Having to remove them, and keep them in a separate case (that I'd have to carry in addition to the IEMs/buds themselves) wasn't something I looked forward to, and caused extra wear to the tips. Only complaint I've got is that, without EQ on my BASN BSG-MC100 IEMs, the audio is very mid-bass heavy, nearly no treble - something that's pretty easily fixed. I can't speak to 'value for money', as I've only had them in my hands for a day, but so far things look pretty positive in that department.

So I have wanted to write a review for a while but wanted to put a few months of use on these first, because in my experience, chinese audio products work great until they die. So a few months in, what is my experience? These things are great, and far exceed my expectations. Battery Life - I have literally listened to these at work all day from 9am to 7pm and didn’t have to charge them. This has been the case multiple times. The battery life is insane, with the case charging I would bet you would get like 40 hours of listening, I seriously don’t get it, nothing else I have used comes close. - Fit - For me they fit great and stay in place, I dont feel them hanging on my ear and suffer zero ear fatigue. Every once in a while the adapter will come off of the inear and ill have to put it back on but that has happened probably 3 times. But everyones ears are different so I’m sure some people may hate it, while others may love it like me. Ease of use - it paired quickly, charges easily, and automatically connects and disconnects with one or both or going from both down to one. I really haven’t had a single problem with the automatic pairing and disconnecting. Once in a while, (two times so far and only while driving) it will like stutter between the headsets, I assume I am passing through a high interference area, and then it’ll automatically fix itself with a button press or just waiting a few seconds. -sound quality- I am no audiophile, my destroyed ears won’t allow that. But I do dabble. I will say this; it is pretty difficult to tell the difference between my 7hz Timeless hard wired into my Schiit Audio DAC/AMP and my 7hz Timeless connected to these. Are there subtle differences? I dunno, maybe? But would I tell those differences while on a roof or driving or working on a unit? Not likely. Now compare that to my Audio Technica M50xBT, the difference between bluetooth and wired is night and day. So I don’t know if I got a magic pair, or if others experienced the same thing as me, but I am quite impressed with this. The case is big, thats really the only downside, not only is it big but its hollowness makes it seem like it could easily be smaller. But since so far my battery life is more than a day on a single charge, it hasn’t been much of an issue, but its an area of improvement. If you have mmcx in ears, and you want to go bluetooth with them, I 100% endorse these guys and hope they keep making them for a long time. Great job making this product guys.

Power lasted quite well; average was 9+ hours on medium volume. Fitment was ok, but that is always subjective to each persons ears. I will say though, the angle of the tip is cast straight into the ear and not at an angle, which caused a bad seal, no matter what tips I used. As others have stated, had to return because case would not close tight and charging quit after about a week (right side in case pins). LED on front of case was nice so you could see how charged up it was.

The noise flow is low (background hum when listening to quiet music) and the connectivity is pretty consistent. However the function buttons are limited to power on/off, pause, skip and answer calls. It would be nice if they also could control your volume, as I find I often need to adjust this while listening to music. So I have to resort to taking out my phone to make adjustments. Also the microphone quality is very poor, don’t expect to be able to have phone conversations with these hooks.

Acceptable pour de la musique ou du multimédia. Mais pas pour du garming (latence importante perceptible), et pas pour le sport non plus. Ca tien bien l'oreille mais la connectique se déboîte petit à petite toute seule de l'iem..

I am an audiophile. I use this bluetooth receivers with high end IEM. These receivers have good amplification. Excellent reception. Long battery life. I wouldn’t compare the details with cabled usage. That is unfair due to the codec an bandwidth of bluetooth protocol. But this device won’t let audiophile down. But the charging container is not nice to some bigger IEMs which have a bigger cavity. Expensive IEMs don’t fit into the charging container because they are a hit too big with so many drivers inside.

dovevano funzionare bene sulla carta, mai pervenute

10/10 exactly what I wanted. I love my Dusks but sometimes the cable is a little inconvenient. The sound quality is pretty good via BT. The cut out in the case for large IEMs is super nice as well. Solid job TRN

First of all I must preface that if you purely want these for sound quality they are excellent for the price, the only issue with the audio quality that I noticed was a slight hissing in the left ear. The main problem I have with this product is the charging case, the most obvious thing is that the case is massive, big enough that you could have issues with fitting it in pockets and even then it’s too big to feel comfortable. The second issue I have with the case is the charging indicator leds they are very bright for their size enough so that having the case in a dark room was actively disturbing my sleep, this is made worse by the fact that the indicators do not turn off until the buds are fully charged and if you are charging the case they will never turn off. The size of the case is something that was done for comparability’s sake but the lights are just ridiculous I have included photos comparing the case to that of the AirPod pro gen 1s in order to highlight its relative size
