Sony’s MDR-7506 are a set of professional level recording studio headphones. Sony has a ton of different headphones to choose from on all levels, and the MDR series of headphones are probably their most popular. The MDR-7506’s in particular are a great set of headphones. They’ve got large diaphragm speakers and are great for variety of applications. I’ve used these headphones for monitoring during recording and nothing else so far. We’ve got a pair of them on hand at the studio where I work and they’re pretty much constantly being used. I haven’t used them for mixing or anything like that, as I never mix with headphones and wouldn’t recommend that you do either. However, these headphones are good enough for checking mixes on for sure. It’s always good to get as many different perspectives as possible for a mix, and these are definitely adequate for that sort of use even though I haven’t had a chance to do so myself. As far as using these for monitoring during recording, they are basically the perfect set of headphones. They have a great frequency response across the board, especially on the low end, which is rare for a set of headphones. They have a crisp high end as well, presenting an overall accurate picture of the sound you send to them. They are definitely more than reasonably priced, as you’re getting a great set of headphones for less than $100 USD. There are definitely a ton of different headphones out there that are worthy of being checked out in this price range, including the Sennheiser HD 280 Pros which are a favorite of mine, as well as other high end Sony headphones in the MDR series, but definitely make it a point to have the MDR-7506’s on your list of headphones to check out as well. Highly, highly recommended for those looking for an overall great sounding set of professional studio headphones.
