First, it gets stuck in customs. Then, when tracking says "Out for delivery," I wait 4 hours by the front door. Tracking says "Notice left on front door." I burst out the door and see nothing. I go straight to USPS. New hire delivered package to wrong door. I wait 1 hour. I get a box the shape of my heart.

Another box. Gotta love them boxed boxes.

SZ2000 earpad replacement surgery prescribed by bass surgeon general @Hawaiibadboy
Taking off the earpad was not simple for me to figure out. I only had experience with Sennheiser earpads that have a hard plastic interior, and I once snapped one in half. I didn't know that the JVC earpads were all cushion and leather, so I was extra careful when I didn't need to be. To take off a JVC earpad, scoop your fingers into the earhole and gently push outwards.
Putting back the earpad was simpler, but also needs figuring out. You see that gap on the outer plastic circle? Insert flap of the earpad on one side of the gap:
Once you have part of the flap inserted on one side, twist the earpad towards that side until it comes full circle and you're set.
Initially, I thought the SZ bass was only marginally louder than the 77's. My basis was the Windows volume level. With a maxed out Fiio E5 and these settings on Equalizer APO, the 77's reach 55% volume before distorting Flo Rida - Low:
HEAVY BOOOTS with the fur
The SZ? I thought they only reached 57%, but after retesting (may or may not have to do with new earpads), they reach 62%, and this 7% difference is audibly significant. The bass difference varies from 5% in songs with extremely low bass kicks such as rap and hip-hop, to 15% in rock tracks with industry standard kick drum beats.
- The SZ has a lower 16ohm impedance and 108dB/1mW sensitivity, while the 77 has a 46ohm impedance and 113dB/1mW sensitivity. This approximates a slightly higher volume for the SZ with the same voltage.
- I might be limited by my equipment. My integrated soundcard possibly starts clipping at higher voltages, so the SZ might have a higher potential that I haven't tapped.
- The 77's enclosure starts resonating before the drivers distort, but this can be remedied by holding the cans firmly into your head. The SZ's are rigid as claimed.
- The 77's crack at high volumes when the earpads are not sealed. This is weird, as if the drivers make use of the pressure inside the seal to sustain a certain vibration, and with average room pressure at high volumes the diaphragms are pushed beyond their stiffness. Covering the vents outside the 77's has the same effect. The SZ's don't do this.
- The stock SZ's are extremely comfortable, which is absolutely amazing considering their weight. The stock earpads are super soft leather with super soft foam, and the headband cushion is made of super soft and resilient polyester fibers, and these super soft physical contacts make you feel like you're wearing a stupid sexy ski suit.
- I haven't tested tracks with delicate, dynamic low frequencies to test bass quality. Now that I can demand my money's worth from my first ever pair of expensive headphones, I might find myself focusing on such intricacies that, previously, mattered very little to me. I still value a great song and worship the divine beat, so I won't be listening to the Blue Man Group only because I want to listen to the novel sounds of car parts, bottles, and cutlery falling off a cliff, like my audiophile cousin.
For the price?
If I can have the maximum bass extreme of the JVC HA-MR77X, and still be able to play frequencies up to 35,000Hz with carbon nanotube accuracy, for $260 I can have my sh!tcake and eat it too. Try the 77 first for $59.95, and if you don't like that bass (ignoring its un-EQ'd sound signature), I DON'T LIKE YOU
