Headphone experience

I also ordered 2 deloops, one audiophile version for myself and one sports version for my friend (who wants a case for his grados since the pizza box doesn't really work :P)
And it was the universal roxanne. Pre-ordered it in mid Jan and they were set to ship end of Janurary. Next thing I know it gets pushed back one month, then another month. I only end up getting them end of March / early April.
As soon as I open them I notice cosmetic defects in the right earpiece in the carbon fiber weave. Not the most noticeable thing but a quick look over showed it very clearly.
I put them on and they sounded really off. Just overall mediocre and a hard fit for my small ears (but still got a seal).
I noticed the left side was muffled / odd sounding but thought maybe I was adjusting to properly placing these in my ears.
I see audiophile friend #1 and he plays around with them and gives me a bunch of tips including some double flange which opened up the sound a lot, gave me a great seal but still had that weird sound in the left side. He puts them on and instantly mentions he hears something wrong with the left side but I dismissed it as probably a fit issue.
I see audiophile friend #2 and instantly tells me the left ear is defective, most likely a blocked tube or something. I listen carefully and yup, that's what I was hearing, just muffled mids making the sound from the left sound weird.
I spent a couple weeks emailing them with no response. I call the phone number on their site to find out it's disconnected. I call the repairs center which give me the correct phone number and I call, ask for Andy (the VP) and he tells me he's going to make this right by sending me a pair of universals that he would QC himself. I send him my address by email and he tells me he'll ship them out the next day. Month later with no replacement, I call up JH again and get Angie who handles customer support. She tells me Andy went to China and won't be back for at least a week. He also never shipped anything out to my address nor had he left any notes saying to send me a replacement. She tells me to cc her into an email to Andy so she can remind him when he gets back. I do that and he actually sends me a replacement. I found out then that the right earpiece of the original set I had was also defective, but to a lesser degree than the left earpiece. The replacement left earpiece has a more clear tint, sounds more clear, etc but now there's a channel imbalance.
Fantastic quality control. Love it.

With Beyer I had bought the T5p and the way the felt case is shaped, it destroyed the part of the cables entering the cups in 2 months. By the third month no matter what I tried I couldn't get any sound from the left side so I called them up and they said they'll handle it. I still had to pay to get it shipped ($50) and it took them a month to fix it because they had to get the parts from Germany or something (well, they are a german company but it's a question of resoldering the cable. I have a hard time believing they didn't have a spare headphone cable around or something).
They didn't charge me for the repair (3 month old pair of $1000 headphones broken because of a shortsighted case design which was changed during production from the aluminum case to the felt case) but I was still pissed.

Those are the only times I've ever had defects / problems in higher end headphones and I've owned a lot including HD800s that were several years old, some older Stax and other cheaper to more expensive sets.

Awful experience with both companies though at least Beyer didn't avoid me.
I also didn't very much enjoy Beyers. I've tried them on lots of amp and dac combos (and not just the T5p, but other models including the T1) and I always felt that the sounded a bit dry / electronic.
Meh, guess that's preference for you.
