Panasonic RP-DH1200

Isolation (2.57)

The RP-DH1200s don’t have the best isolation. They barely block out any lower frequencies and their high-frequency blockage is fairly insignificant. These aren’t headphones for noisy environments.

Leakage (6.52)

The RP-DH1200s also aren’t the quietest headphones. If you’re listening to your music at an average volume, chances are the rest of the room is too. Granted, your playback won’t be deafening, but it will definitely be audible. Even if you have the background noise of an office to mask your music, the people in the neighboring cubes will probably catch a whisper of your afternoon La Bouche marathon. Keep this in mind if you’re heading to a library or quiet cafe.

Maximum Usable Volume (9.61)

This test is basically a battery of distortion tests, only each one happens at a higher volume than the last. The purpose of these tests is to find the highest volume the headphones are capable of outputting before their distortion level hits an annoyingly noticeable 3%. We found the Panasonic Technics RP-DH1200s’ distortion topped out at 118.36dBSPL, which is a great volume. Anything at 120dB and higher will hurt your hearing over a time, so it’s probably not wise to have headphones capable of those volumes. Regardless, 118dB is more than loud enough for normal use.
