My Master & Dynamic MH40 Wireless Gen2 headphones have developed a fault that casues a notification sound to play every few seconds, interrupting playback. I contacted their support who were initially helpful until I sent them my original proof of purchase showing them being out of their (short) warranty. They told me it’s likely a driver or battery issue and they do not make any spare parts available. These shouldn’t be thrown away after 2.5 years.
In retrospect I suppose the clues were there for this company - charging $29 for 3.5mm audio cable.
Obviously I will never buy one of their products again no matter how good they sound. I wonder if people know of manufacturers who do provide spare parts and are on the right side in terms of right to repair?
FiR audio are. They specifically made their IEMs with repairability in mind. Easily replaceable mesh filters, and easily replaceable IEM-side 2 pin connector in case it ever fails.
