ATH-L3000 MDR-Z7 MDR-CD3000

Yes. Two wooden ear-cups are under the leather. I've taken part my L3000. Here's the pic.     https://flic.kr/p/H1wiYC https://flic.kr/p/HjHYYT https://flic.kr/p/JWVXaJ

I have one pair. I agree with you. Exactly, the L3000's lack details. Also, the sound-stage is very small. However, they're very musical. They have outstanding bass and audio-technica-style sound-stage. L3000's are indeed the best audio-technica's headphones.

Hello guy, I have the COS H1. If you want to play games or watch movies, just switch off the button of buffer.   I don't have Z1R, yet COS H1 works well with my ATH L3000 & SONY Z7. The COS H1 has very clear and bright sound. Perhaps it will go well with Z1R.
