To revisit a topic of discussion that was brought up a few months ago, I decided to try the Teak headphones with the wood cups off – only the headphone frame, drivers, and stock pads on.
Surprisingly, it doesn’t sound as bad as I expected. I suspected the headphone would sound harsh, splashy, and thin with little bass. What I got was the complete opposite.
Naked with the cups off, the Fostex drivers with stock pads sound very warm and thick in the bass, incredibly even in the mid-range, and unsurprisingly a fair bit blunted in the treble. On hindsight, I think the felt in the pads helped tame the sound , which explains the wooly and liquid quality of the entire sound as a whole, not thin and harsh as I thought it’d be.
The bass, quite simply, was almost overwhelming in quantity. I think both the squishy foam around the grill and the protein leather pads helped trap the low-end, i.e. removing the foam and using a set of velour pads would’ve almost certainly decreased bass drastically.
Finally, the imaging was surprisingly still very solid, though the right-most and left-most edges of the sound had a noticeable fall-off, due to the obvious fact that there was nothing there to trap the sound in.
Really, aside from the very diffused, wooly, and exaggerated bass, it wasn’t bad at all, all things considered.
Overall, I’d say that while the wood definitely does have an affect on the sound and a role to play, the Fostex drivers in the Teak (and by proxy, the TH-X00) are simply very very good – as you’d expect out of a US$400+ headphone.
I’d be very curious if a mod with vented cups were to be made some day. Even if the cups were made of metal or a dense plastic, I think the results would probably be quite interesting.
