T1 channel imbalance (and Beyer Tesla headphone variance issues) - Page 6

I'm quite interested in this also but I seriously doubt that Beyer would want to open that can of worms. I would hope that they had the means to refute these findings (or at least further explain). I have a pair in the 7K serial number range and they sound just fine to me but I don't have the equipment to measure them. Still these claims are disturbing.

My T1 sounds great for a lot of tracks, Jazz, Rock, Metal, Pop, String Classic but when it comes to certain classical tracks especially with Piano intro, the quiet background reveals some nasty distortion and some kind of resonance. A lot of classical tracks also sound left-centric.

Some Jazz tracks that open with piano produces echoey distortion/resonance on my right cup. Is this the impedance imbalance everybody's been talking about?

 

I am sending this back for servicing. My local dealer doesn't even have Multimeter to test the impedance. They don't have a T1 to compare it with. Beyer needs to up their game.

I bought three pairs of T1 headphones, all of them from an official distributor here in Croatia. One of the pairs quickly started to show strange behavior. The left earphone started to produces strange noise when the amplifier was turned all the way down. It was literally like something was tearing inside, like some paper was being torn inside... Beyerdynamic thought it was my amplifier which of course it wasn't. Then I put them aside and used something else. After a few days, I came back to that pair only to discover severe distortion in the right channel (the opposite channel to the one I heard the noise from) and only slight distortion in the left channel. I talked to Beyerdynamic directly and they told me to ship it directly to their service center in Heilbronn in Germany. I thought that was strange because it is the dealer that takes care of shipping in such cases. Still, I sent it off like they said only to be called by the distributor here and asking why I did that. A complete misunderstanding it seems but unquestionably complete incompetence from Beyerdynamic service technician that spoke to me. The postage wasn't free either. But okay, they took care of it and sent it back. I was shocked to hear that the left channel distortion was still there while the right channel sounded different. Obviouly, no one even cared to read a two-page detailed description I included in the box and I guess no one even cared to test both drivers... That was completely unnaceptable. I sent the headphones to the distributor here and told them I want those things fixed or there would be consequences. It took them two months to get them back to me. When they arrived, I could see that the entire head-band assembly was replaced althogether tnat the exterior rims around the ear-cups were changed from grey to black. 

 

Ever since this catastrophic experience, I have refrained from buying Beyerdnyamic stuff. I still have a few of their microphones and they are good and pretty rugged for sound reinforcement but headphones... After I made sure they worked properly, I sold that pair and informed the customer of the troubles that I had. I literally sold them for a sandwich and a can of soda, that is how much they were worth. I subsequently sold the other two pairs because they ultimately didn't work for the application I had in mind. I'd probably sell all three of them for that reason but that doesn't change the bitter taste I spent 800 Euro for something that was so flawed and half-a-product and that should have been state-of-the-art. I just don't understand how a respectable company can allow for something like this to happen. 

 

Even when people buy cheaper stuff, they expect it to work. When people buy expensive stuff, the last thing they have in their mind sending it out for repairs long before the warranty has expired. That is more than an inconvenience, it's idiotism of the worst kind and you can be assured that that customer won't be going back and will take down as many customers as possible. The Beyerdnymic experience is the worst experience in audio I have ever had.

I am sorry to hear about your awful experience with beyerdynamic. That is really strange, their customer care has been getting a lot of praise on Head-fi. I hope you enjoyed the T1 while it lasted, and have found a different headphone at its level :-)

Thank you! I did enjoy those headphones immensely and loved their sparkje in the top end. It's a sad story but these things can really make things difficult and I can imagine someone who spared quite a long time in a desperate situation. Beyerdynamic should take care of their customers better.

It's my experience that service departments NEVER read any instructions or explanations you put either in or on the box, even if they specifically asked you to include as much info as possible. This is the First Law of Service Departments, which all consumers should know. 

 

As for "idiotism", though I've never actually heard of the word before, it certainly does describe what there's a lot of around. tongue.gif

Yes, the customers might as well learn how to make headphones and then sell them to themselves. The only thing a customer should know is that he's getting what he paid for. Now I am sorry but I don't give a damn about their policies with regards to dealing with customers. If they cannot provide quality service, even in these times, then they might as well go under. No one will cry for them for there were more accomplished companies that did go under.

I've had my first and only pair of T1's for well over a year now.  (Still working perfectly).  I got them re cabled twice.  The first time was with a Zeus Cable.  I really didn't like the ergonomics or the looks of that cable.  I recently got them re cabled again to a Norse Audio Skuld v2 32 cable.  This cable is not only great ergonomically - it's great looking as well.  Most of all it's very transparent and does not hurt the sound of the headphones.  Hell, I think it tamed the highs a bit.

 

I've been very happy with the T1's.
