Another pad rolling impression, this time the stock pads from the TH-610 (Fostex EX-EP-61).
Ever since I got the Hifiman Ananda, my ears felt too cramped in the stock E-MU pads. The ear hole opening is just a bit too small for me now, so it puts pressure on my earlobe. The TH-900 pads would be the roomiest, but I've noticed in my other pad-rolling attempts that the off-center oval shape attenuates a lot of the Teak's treble. I heard the TH-610 pads were just slightly bigger than the Teak's, so my hope was it'd be roomy enough without changing the sound too much.
The pad opening is indeed larger than the stock E-MU pads. It's still snug on the ears, but the difference is noticeable for me because I don't get pressure on my earlobe anymore. They are still shallow though, so if your ears stick out, these won't help.
There were a few more differences that I noticed. The stock E-MU pads have a more pronounced hump on the back side while the Fostex pads are flatter, so this can affect the perceived clamp force. The pleather material is different, the E-MU's have a smoother texture to them while the Fostex is more similar to Sheepskin. Both pleather materials are good quality though.
Sound-wise, there are changes. The Fostex pads add a touch more treble energy, though not as much as any of the other pads I tried. Bass loses a little quantity and gets tightened up so you lose some warmth in exchange for clarity. Mids don't seem recessed, but the soundstage presentation seems a little less intimate. Overall, I'd say these make the Teaks sound more neutral. The Accessory House pads are the closest in tonality, but they sound leaner than the Fostex and the ear holes aren't as roomy.
After these, I've decided to stop pad-rolling on the Teaks. The touch of warmth and intimacy is really on-point and making the Teaks even
slightly more neutral kills that rich, full-bodied sound. It really is similar to the HD6XX in that regard. I'll be putting these pads on the E-MU Urushi though, since those do benefit from having the bass tightened up.
