Review: Satisfaisant, recommandable, mais attention à quelques points - 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.

### ⭐⭐⭐⭐⭐ Bargain!

Great battery life and a comfortable alternative to Shure’s adapters I use the Fanmusic TRN BT20 Pro True adapters with my Shure SE535 earpieces, mainly for spoken-word listening rather than music. I am an audiophile, but I use a separate pair of wired Bluetooth adapters when sound quality is the main priority. The battery life on these is absolutely amazing. I normally use one earpiece at a time and switch between them throughout the day, which gives me a huge amount of listening time without ever being left without a charged earpiece. I regularly get around 12 hours of continuous use from each side. The connection is stable and does not keep cutting out. The sound quality may not make the most of what the SE535s are capable of, but for my listening needs it is perfectly suitable. They sit comfortably behind the middle part of the ear and feel noticeably lighter than Shure’s own TW2 adapters. My TW2 adapters kept breaking down every few months, and the repair costs were becoming expensive. Overall, these have been a great purchase: excellent battery life, reliable connectivity, comfortable to wear and far better value than repeatedly repairing or replacing the Shure adapters.
