I've said this before, but I've had mine since launch day on Verizon which was October 31st of last year. So I've has mine almost 11 months now. The entire experience has been great. The phone has been flawless.
I tried the EL8 with my V10 for about a minute the other day. It needed a decent amount of volume on the low gain mode. It would be one of the headphones you'd want to trick into aux mode on the V10. Wasn't a super efficient headphone.
