The reason why this tipped me off is that I hear the ringing happening sometimes when I pause the music. It's also significantly louder on the left cup than the right cup.

So... what exactly do I do if I want to have these looked at?

Probably start by emailing Chan at enquiry@emu.com or Massdrop, if you purchased through them. If that doesn't work, you might start asking around for a DIY'er around these parts.

Hello. Long time happy EMU Teak user here. Can anybody here comment on the Amiron Home? I am looking for a second pair of open headphones to complement my closed EMU Teak. Any comments from own experience will be appreciated, thanks.

The wood definitely alters the sound, though not drastically in this case. Here are some measurements:

This also is true of the Fostex TH-X00 and TR-X00 series, as well all the ZMF headphones. Wood matters.

Hmm interesting. My guess is that only the cups would affect but not the "ring" like the Audeze LCD 3. On another note, where could i learn more about how to read these measurements? =/

Correct. Cups tend to help in absorbing the sound emitting from the back-end of the driver. That wood, along with damping material, distance, and internal geometry, helps to balance attenuation and reflection of the sound. With a lot of damping, bass doesn't reflect back, making the sound cleaner but less bassy. With a lot of reflection, you get more bass, but also more distortion. That, of course, is assuming all other factors remain the same. Rings, like on the Audeze LCDs or some HiFiMan headphones, do nothing to the sound. They are purely aesthetic.

Here are some good resources to get started on understanding measurements:

Thank you so much, these are great resources, and very informative response. =D

@phthora from the https://www.teachmeaudio.com/recording/sound-reproduction/fletcher-munson-curves/ and I quote
The Human Ear
The human ear operates by sensing pressure variations above and below atmospheric pressure. The process is as followed:

  1. A sound wave entering the ear canal exerts a fluctuating pressure on one side of the eardrum; the air on the other side of the eardrum is at atmospheric pressure.
  2. The pressure difference on the two sides sets the drum into motion which in turn oscillates three tiny bones in the middle ear called the ossicles.
  3. This oscillation is finally transmitted to the fluid-filled inner ear; the motion of the fluid disturbs hair cells within the inner ear, which transmit nerve impulses to the brain with the information that a sound is present.

If one side of the ear is based on atmospheric pressure, I wonder then if sound from any headphone would sound different when in a higher altitude place where the pressure is lower? Sorry if I'm bothering you with these questions.

Not a bother at all, though after this we should take it to a thread in the Sound Science Forum. Feel free to tag me there.

Atmospheric pressure likely has a measurable influence on hearing, but I doubt it is even remotely significant. If it were, you would also be able to hear differences resulting from low/high pressure fronts due to weather or pressure changes due to temperature. Moreover, there so many of those tiny factors affecting hearing in insubstantial ways, that atmospheric changes are probably going to be balanced out by other factors. Things like time of day, mood, physical health, smoking, hypertension, age, fatigue, body position all have much larger impacts on sound anyway. And even those are typically less impactful than things like headphone position, pad condition, or fit. In short, there are a thousand factors affecting sound and it be utterly ridiculous for someone to say something like, "Of course you didn't like these headphones in Miami! But, you should try them in Denver!" Although, I'm sure you can find someone who's made that claim...

fair point. the position of pads, fit, ear tips and whatnot affect the sound for sure, I have experienced these before.

Anyone have an idea of often these headphones end up on Massdrop?
