I love these things, very very nice headphones. I have been throught the usual $300 - $400 range of open and closed headphones, these are way better, open, responsive, comfortable. Why four stars then Marc? The cable and Drop support, I just don't get it. There are kinks in the cable that I can't seem to get out of the cable, it does not lay flat on my desk and always seems to be in my way. They sound really good though so I will deal with it. The other reason is the headphones arrived with a 4pin XLR to 3.5mm adapter, this is how I connect to my MacBook and my amp so it was required. Only one channel works using the adapter due to a defect. These headphones are expensive, I expected some quality control. I opened a ticket with Drop and waited 2 days for a response, that is too long to wait in my opinion. The response was send back for exchange, refund or accept a 20$ refund to source my own part. I found this unusual as I asked for only a replacement adapter. I was able to source a new adapter (after 3 tries) through Amazon for $46.00. If I bought these used I would expect this level of support. Moving forward, no matter the savings I will think twice about buying from Drop.
