I've run into some trouble with He-560 headphones over the past year. I've had to return the headphones multiple times due to the strange "popping" sounds in the drivers, scratches on the gimbals, etc. With the qc issues at Hifiman, I asked for a replacement but this time they said they will be giving me a refund on the headphones. A rep emailed me to return the headphones where I pay for shipping. Okay that's fair, but over the past several months I've had to pay an exorbitant amount of fees for shipping and wait quite a bit while I received my new pair. Now since I'm receiving a "refund," I shipped my cans yesterday and the company informed me today that they don't have the figures on how much I will be refunded. I'm pissed beyond belief now because they can technically say that they'll refund me half the price and I'll have lost the fees on shipping once again. This company has been driving me crazy but hopefully I can get the whole refund because they aren't replacing my cans. I thought customer service was plus for this company; I've had to deal with a myriad of issues in the short time I've had these. I received $767.54 because HiFiman complained that they had to ship my cans a few times. So, after PayPal's fees and HiFiman's "repeated shipments" of multiple defective headphones, I'm getting $150 less than what they promised me.
