I removed the vocals and other instruments in Wiz Khalifa - On My Level and isolated the bass track, which I used for testing. So while the headphones may do better with specific sine waves, it may not reflect real-world reproduction. On My Level has become the community favorite for testing bass (hardest impact kick drum and teeth chattering subbass), so it was only apt to continue using it as THE bass benchmark. The SZ2000 reached 125dB maximum before distortion. Compare this to Hawaiibadboy's basscannon that started it all, the JVC HA-MR77X, which only reached 109dB before distortion. This 16dB difference is quite significant in terms of perception, determining the fate of your experience between an average loud home listening and a front row rock concert. For the SZ I used the 77X earpads sealed with packaging tape. The RadioShack Digital SPL meter can record up to 126dB, and is accurate by -3dB from 30Hz to 1KHz compared to an Earthworks measurement mic as measured by RealTraps.
