Direct Sound EXTREME ISOLATION EX-29 ダイナミック密閉型ヘッドフォン/周波数特性 20 ~ 20kHz/インピーダンス32Ω/感度114dB/遮音特性29dB
But if you think you are going to track drums in the same room as the performer and use these to block out all of the direct sound so you can hear what the mics are picking up, think again. Drums are waaay too loud for these (I don't even know if there is anything that can block that out completely). If you push these things hard against the side of your head you can kind of block more direct sound out, but obviously then you have no hands to do anything else.
For tracking less extreme instruments like guitars, vocals, some brass instruments, etc. they are great though. Really good for moving the mic around to find the spot you want on an amp, for instance.
EDIT: Second pair was shipped very quickly. Second pair is working very well. Also: apparently, the plastic headband on these phones is meant to replaceable instead of sending the whole phones back. Maybe next time I'll try that. But I still say the headband I had first time around should have lasted longer. We'll see how this round goes.
- sound isolation: pretty good, dogs can be barking in the house and it sounds like a very muffled distant bark
- speaker quality: "ok". limited sound range and quality compared to better headphones.
- comfort: "ok". but for any brand that cups your ears, ears get hot/sweaty with prolonged use (perhaps cloth between the ears/headphone could prolong endurance? I haven't tried it yet)
- very cleanable: all the surfaces are plastic or rubber except the speaker cloth, so if you're in an industrial work environment, that's a plus
- each ear cup has a wire coming off of it, which is kind of in the way and annoying
- there is no "left/right" wording. the inside of one ear is red and the other is black. the red is the right.
- there is no wording or branding on it at all
- simple clunky injection molded
overall I'd say:
if you're going to spend more than 30-40 on headphones, go with something better.
I really disappointed and will not be buying these again.
I want constant sound isolation. These headphones failed at that.
Context: I have an anxiety disorder, and sudden sounds freak me out. I need a white noise machine for any chance at sleeping- and a dedicated one, not just a fan. I have a collection of websites and playlists for background noises to drown outside sounds. I'm always shopping for good headphones. If I don't get it right, I'll jump out of my skin over practically nothing.
I told you that, to tell you this:
These headphones were amazing.
They blocked outside sound more than any other set of headphones I've used before. Even without any sound playing, they were as good as earmuffs. I've only bought in this price range, so I can't speak to more expensive headphones. What I can tell you is that someone who is extremely sensitive to sound thought these were heaven.
So why did I give them two stars?
Because they lasted about a month and a half.
That's a month and a half of me wearing them almost every waking hour. That's a lot more demanding than the average person, so you might have better luck than I did. If you want sound isolation for occasional use, these are incredible for it.
But just occasional.
For me, as a drummer, I was seeking the sound isolation - they do isolate the sound very well, however, external bass drum sounds created a 'boom' resonance in the headphones that was unusable for me. I believe this resonance was caused by the hard plastic shell of the headphones echoing the the sound into the headphone chamber. I was surprised this happened - some cheaper headphones with softer shells did not exhibit this issue.
