MDR-7506 : Great upgrade from HD25!

I've been a long-time user of HD-25 for the location sound recording purposes and never quite got used to the uncomfortable and unnatural, over-emphasized bass boost they produce. While this was somewhat helpful during the live monitoring in order to keep the boom pole handling as smooth as possible, the headphones themselves were unusable for any other application. As a consequence, I often had to carry a pair of my well trusted Beyer Dynamics DT880 to listen to the rushes at the end of the day for a proper reference of what was truly captured.

When I finally had the chance to try out the MDR-7506, I was amazed by how their closed-back technology allows even more analytical monitoring than the HD-25 while offering at the same time a frequency response curve that is far flatter and natural sounding than the one of Sennheiser.

In my experience, Sony's MDR 7506 ear pads are also more comfortable than the HD25 but I haven't tried the new one they recently made available. This impression could also partly be the question of just a more natural-sounding reproduction of Sony.

In the end, these headphones are also cheaper than the HD25 so if you're an HD 25 fan, I would definitely recommend giving them a try!
