Today, I'd like to express my utmost disappointment with Sennheiser IE800s quality control. As I already have and have been using IE800 for over a year I thought it would be a no brainer to upgrade and get a fresh pair of IE800S to couple with my newly purchased AK SP1000M only to find out that TRRS 2.5mm balanced adapter was faulty and the IEMs wouldn't play music through it. I tried it with my wife's AK SR15 to rule out hardware issues, but alas... I could not believe that a product which costs as much as $1500AUD would have a faulty adaptor cable. Anyway I decided to suck it up and headed back to the store (official distributor) where I purchased the IEMs to ask for the adaptor replacement from a demo unit BUT it wouldn’t work neither with mine nor with their demo IEMs!!! After trying multiple cable permutations, we could definitely conclude that it was the adaptor cable. The batch number of my set was #304. The batch number of the demo set was #300. Pretty close. I could only assume the whole batch might have had the same problem. I opted for full refund as I wouldn't wish to wait extended period of time for the replacement part of a HI-END! product as I firmly believe that such merchandise must have had exceptional quality control before it reached the shelves.
The whole experience with Sennheiser IE800S top of the line IEMs is ruined for me.
For headfiers who are reading this, I would suggest to test their 2.5mm TRRS adaptor cables and replace them before the warranty runs out.
Attaching the photo of my invoice as proof.
