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

Frequently desyncs when in bluetooth saturated environments like gyms or libraries, making these almost unusable outside of the house. Gutless sound quality, chunky and plastic charging case that can’t even fit IEMs inside.

mine seems to have a loose connection on the right ear piece which results in static. it resolves if i move it which is irritating.

They're fine. The audio is good battery life is outstanding at well over 12 hours but the case sucks. I can't find any one of these units to have a stable charging connection pin lock. The pogo pins wear out immediately and all they do is hunt for a signal and hijack signals until you prod them enough to stay red and charge. How can anyone improve contact?

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

Spot on! Works right out of the box... Bluetooth Sound has a tiny bit less low end with my TRUETHEAR ZERO RED's than wired, but barely notable. Still sounds better then my Apple AirPods. GREAT product!!

Pour les amateurs d'IEMs qui désirent une solution sans fil moins honéreuse qu'un DAC externe sans fil et plus pratique que ce dernier, les TRN BT20 Pro sont de très bonne facture. La qualité de son n'est clairement pas époustouflante, mais elle convient à un usage régulier, tandis que la batterie tient aussi très bien. Attention cependant, notez bien que les IEMs ne sont pas inclus. Ces adaptateurs servent uniquement de connecteurs sans fil. Vérifiez également bien que les broches correspondent au modèle d'IEMs que vous comptez y brancher. Je les ai utilisés avec des Truthear Hexa. Attention également au volume qui peut être atteint. Ce dernier est relativement bas car l'amplification n'est pas énorme. Néanmoins, cela convient également. La tenue est très bonne. Il est possible de courir avec sans problème. Cependant, le boîtier est quelque peu gros. Ce n'est pas extrêmement pratique. De plus, les IEMs, si trop gros, peuvent ne pas correctement rentrer dans le boîtier aussi. Un point à surveiller également. Ne pas hésiter à se tourner vers d'autres modèles de la marque si ceux-ci ne conviennent pas. Enfin, l'appairage à deux appareils fonctionne très bien et bascule automatiquement d'un appareil à l'autre de manière intelligente, tout en mettant en pause l'appareil précédent si possible.

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.

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.
