We had two people in the last week on this forum that had theirs die. The Aria thread here only has 197 replies from fewer than 50 people. Starting in September discussing the poor construction quality of the Aria is the primary topic of the thread.
From what I can tell on that thread 4 failed of 49 users, and two more have loose cable connectors that I don’t know the current status of. Only using the confirmed failures, that is a over an 8% failure rate, and this IEM is barely six month old.
That seems excessive
