I'd greatly appreciate your recommendations for a headphone with crystal clear sound purely for transcription and transcription editing purposes and not for music, and also sound isolating. My budget is around $100. Thanks!
Look at the Plantronics Blackwire 600. I used an older plantronics headset in my very loud office a few years ago, and it worked flawlessly. The sound cancelling is amazing on these things. It's technically used for phone calls, but all of the noise cancelling features work via PC audio.
