This review is from: JVC HAS400W On-Ear Headband Headphones, White
Pros: Sound: flat frequency response 200-20kHz. Flat & fast spectral decay rate. Low harmonic and phase distortion. Good efficiency, flat impedance response. Great tight bass due to fast spectral decay and low harmonic and phase distortions. The bass goes LOW. Not as earth-destroying as HiFiMAN or Audeze obviously, but for a 40mm on-ear I'm impressed. Carbon nanotunes at work.
Comfort: the lightest headphones with 40mm drivers I've ever worn. Soft pads with ample thickness. They couple with my ears the best with the front edge of the ear, and the flattest part of the pads just cover the rear of my ears. More than ample but not too much side pressure, and the pressure doesn't increase a lot with wider heads like mine.
Almost completely white headphones. I like the style a lot.
Cons: The bass is ~3dB above subjectively "flat" response. The bass starts out even higher at first, especially in the lowest lows, but as they burn in the bass boost gets very flat up through ~150Hz, and in general it settles down and the spectral decay also catches up with the mids & highs so the bass sounds tighter despite not having as "diggy" low-lows.
Almost completely white headphones. Very easy to get dirty, and I hope I don't find out how hard they are to clean. These do come in black, but I got them because they are white. I wanted a pair of stylish headphones for once.
Other Thoughts: These took about 40 hours to burn in most of the way. Start out with the loudness soft for the first day or two of burn-in, and then work your way up toward your usual maximum listening level. Do yourself a favor and use a player with ReplayGain to do the burn-in so there isn't any super loudness war'd junk that plays in the middle of the night and pwns your headphones. These do have a lot of power handling, but be careful anyway when doing unattended things with any gear. Heck, you might even like ReplayGain enough to use it just while listening.
I don't like lots of side pressure, and often end up "tweaking" that with headphones that allow it via a steel headband. So these shouldn't press too hard on your ears, but they are tight enough on my head to not worry too much about them falling off while running, for instance. If you're going to sweat at all in these, do yourself a favor and get a black pair. Clean your ears often as well, or you could easily get ear wax onto the white cloth mesh filter/screen protecting the driver which would stain it.
Pros: Good action, handles fast typing with many keys pressed at once. Action starts out a little hard to press but it gets a little easier over the period of a week of use.
Cons: Slightly non-sensical layout of multimedia keys, and a tiny backspace key but a HUGE enter key. Caps-locks etc lights are difficult to see unless standing above the keyboard. The right side of 1 of 3 I've ordered is a tad harder to press than the left side, even after a week of break-in. For the price; it's not big enough of a difference to complain about much, and it's something that's easy to not notice.
Other Thoughts: Thanks for the awesome service NewEgg. :)READ FULL REVIEW
tons of connectors
Cons: not modular, but you shouldn't need this many connectors in a small case anyways
Other Thoughts: working fine with heavy gaming... Windows 7, i7 860, nVidia GTX460 (260.99 "Xtreme-G" drivers, "balanced" power setting), ASRock P55Extreme, 4GB 1600mHz DDR3, 60GB Corsair SSD, 2TB WD Green, Lite-On BR/DVD/CD burner, 4 case fans ($180 Lian-Li case), and several other things like floppy, usb devices, etc... no problem at all. the PSU fan doesn't run up fast at all, and it doesn't get any warmer than the air coming from the case already. It *should* do ok with SLi of two GTX460s.
On the HEC website, they list that the software (within the PSU) shutoff protection is now at ~150% of the rated maximum load, so at least so far I haven't had it shut down from any potential spikes.
