MoerDuo™ Bluetooth 5.3 Auracast Audio Transceiver

3ヶ月前に購入。 数回の使用で壊れた。 保証ポリシー的に1年保証のはずだったが、 販売元に問い合わせたところ、返品や修理の為に日本からの返送は当方負担とのこと。 保証とは？？？ また、PCのアプリはWindows版しかなく、やや面倒。 大変勉強になる買い物だった💸

I have been looking at assistive listening tech for decades, working in a couple of churches to work with induction loops. Sound quality is a bit Dalek on induction loop and there are dead zones in our setup, so I keep looking for something modern. Classic Bluetooth provides good connection but for only two listeners who must be paired with the transmitter. Auracast finally provides broadcast, and Moor Audio/MoerLabs looks like the only option so far. I have two of these dongles; one will live on a line output from the mixer and the other will be either an input to a livestream laptop or drive someone's headphones. I shall be back for more ;) but they are 'Unavailable' on Amazon.com and seem to appear only occasionally. Connection with these is good within their reach (in the same hall but the transmitter is behind a wall). Volume is low to headphones as the input is only line level; I must either feed the transmitter with boosted audio or give the listener a pocket amp - I plan on the latter as I expect these have a 3.3v class D amp with limited power. I am expecting volume to laptop (via a sound card) to be adequate. Note that the dongle only receives sound via USB; it will not provide a sound input device to a PC, thus I used the jack socket to a USB sound card. Sound from the little supplied lavalier type mike is loud and good. I could tape the dongle and mike to the lectern if necessary. Sound from the L-R inputs on the jack is probably delivered to the receiving dongle's jack at the same level. Pairing is easy - choose Rx or Tx, long press to turn on, three presses to choose Auracast. They stay configured for next time, so you only have to turn them on/off. Moor-Audio.com (Taiwan) also do headphones; I haven't tried these but as I can knock up a pocket battery headphone amp I have all the gain I need. Put them back in stock!!! Looking forward to Auracast going mainstream.

AURACASTのトランスミッターとして購入。箱を開けたときにはびっくりするほど小さくて、本当に使えるのか？と思ってしまいましたが、問題なく複数台に送信できました。必要な機能がコンパクトにまとまっており、良い商品だと思います。技適マークもあり安心して使えます。

Poor quality. I bought one for broadcasting presentations and church services to guests, and it worked fine at first, so I bought 2 more. By a month of gentle use by mostly elder folks only once per week, one of them had a poor connection where it had to be held a specific way in order to output audio to the connected headset. The others had good connection but the audio quality deteriorated. It sounded robotic and cut out frequently.

Bought this to use with my Resound Nexia hearing aids. Literally took me 3 hours to get it working and I am very tech saavy. Instructions were useless and the internet had no easy instructions. Sent me to my phone, was not clear how to change the sampling rate. I have not yet used it in a real world situation, but appears to be clear and working well. Would like to use it on my tv as well, but don't currently have a way to connect it.
