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

Case is a little bulky in the pocket but accommodates very large iems so I suppose thats fair enough. The largest I have are the Mangrid Tea2s and those were no problem, although I have them connected to Moondrop Lan's for regular use. Battery life is good and I only charge the case once or twice a week right now, and their energy saving mode while not playing anything is great! I've fallen asleep without putting them in the case only to find them at 5% less battery than they were the night before. Bluetooth startup sounds are thankfully not deafeningly loud and are pretty close to my regular listening levels. Maximum volume might be a touch low if your iems are less sensitive but I am very comfortable listening at 65% volume or less. Sound quality is good, more than reasonable for the price. I've been using AAC and noticed no noise floor or artifacts, although there might be a touch of distortion if you're driving these at max output. Haven't tested the mic quality myself but haven't gotten any complaints about it either

I use these at work to listen to audio books and they last a full 10 hour day of constant sound near max volume with battery to spare! I compared them with my earbuds wired running off an atom amp listening to 320kbps music and i couldn't hear much of a difference. Only downside is limited codec choice and high latency. P.s. the 0.78 model came with the 2 pin connector that fits into a little square hole on the earbud

I enjoyed these while they worked. Unfortunately after a few days one of the sides became very quiet, rendering them unusable. Clean connectors and the IEMs work fine wired, so I know it was the adapter. Open to advice on how to fix

The build quality is high, especially considering the price, and is comfortable and has well designed controls. However it sounds truly horrid- there is *very* audible distortion/clipping at normal (not super loud) volume. If you plan to listen to music with them, you will be sorely disappointed.

Full volume is something left to be desired. Otherwise its very functional. Battery charger case last super long. A little muddy when its turned all the way up but hey. Its 20$

Work's amazing exactly as advertised. The case Is a little big but it makes sense because it goes around your ear. PS: they do work with moondrops smaller IMS

Good product, I've been testing it for several days, the sound quality is good and it has good range.

The sound quality is lacking compared to the KZ AN01 that I had but they hold up well to sweat unlike the AN01. The downside is the pogo pins in the charging case get stuck down and don't make contact with the earhooks, causing them to connect to my phone and drain the battery. A little isopropyl and tweezers to pull them up usually gets them working again but it's annoying. If you're in the market for BT earhooks that will do the job, then these aren't bad for the price but if you value SQ get the KZ AN01 for its LDAC support and a better amp, or look into an IP rated option. But don't buy the AN01 for working out, they will not hold up to the sweat.

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

Great! It was compatible with my Moondrop Aria. Easy to use, simple to connect and super comfy around my ears. More comfy than wired. I just wish they had an app so I can make tweaks.

No baja demasiado la calidad de sonido, pero se quedan encendidos mucho tiempo dentro de la caja.

Depending on the IEM you plug into this thing (LETSHUOER S12 PRO), the sound quality can match top tier earbuds in the market. (if you dont need ANC, transparent mode etc) You dont really feel the weight of the battery tho the case is rather bulky. (again its bascially the same price as all the other Bluetooth transmitter in the form of earbuds). Niche use case, if you are mostly using it in a environment where you do not need ANC, this is easily a great option utilizing your existing IEMs and turn them into wireless earbuds.

Buen producto buen sonido , un poco grande el case y el módulo pero cómodo lo recomiendo.
