The HE-400i is a very neutral sounding headphone, not much emphasis or recession anyway and high frequency extension is better than 99% of headphones. On the other end of the spectrum however, bass extension is linear until 40 or so hertz, then it begins rolling off. I think this is due to the way the earpads are dampened. Typically planars have very linear bass extension, but I don't think its that problematic, especially considering most open-dynamic headphones are much worse in this regard. One thing you would expect from a planar is a smaller...

The Sennheiser HD280 that I'm reviewing do not belong to me, they're presumably a couple years old (I didn't ask) and in good condition aside from a couple scratches on the earcups. I was curious to how they sounded, especially in comparison to the HA-RX900/700, ATH-M35 and M-Audio Q40 (all of which I don't presently have but definitely remember quite well). I do have Sony XB90EX, Fostex T50rp II (modded to be flat aside from a spike at around 8 - 10 khz) and MDR MA900. All very different headphones, but yeah on to the review.   Build Quality: 4/5...

I got these off a friend for 40$, they go new for about 60 - 70$. The driver appears to be of Audio Technica origin and the fact it's 53 mm, which makes my guess a lot more likely. Sound-wise it's a bit artificial but expansive sounding for a closed headphone, changing the pads helps make it sound less artificial. Comfort is alright, they're not as heavy as my T50rp II and are a little heavier than my ATH-M35s and they're kind of large but adjust just enough to fit my head, which is subjectively on the larger side. They're very easy to drive with my...

I bought this headphone twice, because I like it a lot. They're good for the money, not perfect but definitely great. First, I'll talk about build quality and comfort, then efficiency and sound. (and also a bonus category of how moddable they are)   TL;DR review: 9.5/10 overall. Sound/value easily 10/10. Comfort 9/10. Build quality 8/10. Does not need amp, benefits from one. They're easy to mod for beginner DIYers.   1. Build Quality: 4.5/5   I'd say the build is the only part that shows they're a cheap headphone, don't get me wrong --...

The M-Audio Q40 is the first high quality headphone I've owned, despite this I can still be honest and accurate about the qualities of this 'phone without overselling it. Let's start with the build quality and design. The plastic that this headphone is mostly constructed out of is rigorous and it'd take quite a bit of effort to break and in no way feels cheap, brittle or flimsy. The headband is malleable to a degree, but I'd be careful and not overestimate it's flexibility or test it's limits because it's definitely capable of being bent or...
