beyerdynamic DT 770 PRO Studio Headphones - 80 Ohm

Product Information

Bought them from Guitar Center and the receipt from says they're new, so I guess I'll have to trust that. They don't seem worn. The DT 770 PRO is a closed dynamic headphone and has been designed for critical music and sound monitoring. The single sided cable makes the handling of the headphone easy. The cushion system allows the DT 770 PRO to be used comfortably for long periods of time. I still don't know what or why - but after an hilarious amount of pain, it turned out to be the adaptor ...Oh, and my meter is now reading 88.8 ohms for each driver (in case you care)

Bought them from Guitar Center and the receipt says they're new, so I guess I'll have to trust that. They don't seem worn. I've just spent about six hours trying to work out why (when recording with Reaper) the mix in my headphones was in Mono ...I've installed new ASIO drivers, gone through every setting in Windows 7 and Reaper ...you name it, I've done it! Finally I removed the 1/4" adaptor and would you believe it, the problem disappeared! ...STILL with a "no short" across the adaptor with the multimeter! Hey there! I've been lurking here for a while, and recently needed a headphone upgrade. Following the advice of users here as well as what I've found out from my own research, I decided upon the Beyerdynamic DT770 (250ohm version). They just arrived a day ago, and so far so good. Probably some of the comfiest headphones I've ever worn.

Currently, these are unamped. My amp should be delivered tomorrow, and I will give it a try and see if this resolves its self. Could this be the cause? From what I've read around here and other places, this shouldn't cause any damage either.

However, they're not playing stereo sound. Left and right channels are heard at the same volume in both ears. I've tried with several sources to the same result. I can set my source to 100% left or 100% right and I still hear it equally in both ears. Prices valid in stores (all including VAT) until close of business on 1st November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) Through all this - AT NO TIME could I read a short (or even a high resistance) between the Left and Right pins of the 1/4" plug.
