So, last year I bought a HD660s and a FiiO K3 when I was in the USA traveling. I was enjoying the heck out of it, and then, May of 2020, the left side of the headphone just went silent, without a reason and without giving any signals. I sent to warranty, but because I live in another country, the dealer had to make a bridge with Sennheiser USA, and they didn`t had the HD660S in stock, only in August.
So I was using my trusty WH1000XM3, and decided to buy an AKG K702, brand new, to try a different sound signature and the claimed soundstage that the K7XX line has. I was liking it for classical music, but 3 days later, guess what? Yeah, left side went silent. I got a refund from the store I bought it and returned to my trusty WH1000XM3.
I was really pissed, so I started investigating what it could be. I narrowed it down to the amplifier and stactic electricity. So I exchanged the FiiO K3 for a FiiO K5 PRO, and changed the carpet floor in my office for vynil flooring.
Sennheiser sent the replacement directly from the USA to me, and I had to pay taxes to get the headphone. I paid it with the intent to sell the headphones once they arrived, and I bought a second pair of HD660s straight from Sennheiser in my country in August. The other pair arrived from US in october and I sold it, and the new one I bought here was working like a charm. Until today.
It's no mystery anymore, but I was using it at night yesterday, put it down to go to bed, when I went to use it today, the right side was silent. Back to the Sony.
The first HD660s got the left side voice coil busted for some reason, and I believe the same happened with the new one. I tried different cables and sources and it never worked.
I have NO clue what is going on. I thought it could be bad electicity but my PC should give me signals, and all my other stuff too, the Sony have electronics inside, and I use it plugged into the K5 all the time, and I never heard a single hiss or noise coming out of it. If anyone have a clue on what may be happening here, I would love to know.
I guess I ran out of luck this year or I'm not supposed to enjoy a good open back headphone for some reason. So I'll try a refund with Sennheiser instead of getting a new pair. This is ridiculously frustrating. My cheap pair of headphones that I had before the Sennheiser still works just fine...
