Best praise vs top criticism for Sennheiser IE 900
“Have been using the IE 600 for a couple of years now but I always wanted to upgrade to the IE 900 some day. That itch, you know. We all know how it is. So, this day has finally come. Super excited to thoroughly check them out :) When I was in Tullamore, Ireleand at the Sennheiser factory almost 4 weeks ago, I briefly had the chance to finally listen to them even if it was just for a couple of tracks. It was, however, enough time to know I wanted to get them very soon. So, here they are :) Happy holidays, everyone!”
“Seems the entire IEX00 line has some design flaws. From the 200 all the way to the 900, there are reports of abrupt failure often before expiration of warranty. There must be something fundamentally flawed with design choice shared across this product line and Sennheiser needs to acknowledge it and fix it. It's one thing for this to happen with the cheaper IE200 but the IE900 failing this regularly is inexcusable.”
