Your question triggered a memory of a similar pair of headphones. It's the Lasmex L-85. No idea if that's an earlier iteration of the L-90, or something totally different (it looks extremely similar). The L-85 was discussed in this HF thread: http://www.head-fi.org/t/817590/lasmex-l-85-headphones
(L-85 didn't sound very promising in that thread)
Agreed, the few that reported back (on the L-85) said they sounded pretty meh. The Philips SHP9500 is almost half the cost and walks all over the L-85.
One odd thing about the L-90 is the manufacturer's photo identifies them as "fully enclosed headphones". I assume that means CLOSED back (vs the open-backed L-85). The "grille" of the L-90 could just be fake/for looks, just like it is on the Xiaomi Mi Hi-Fi headphones:
The L-90 sure does look sexy though.
Interesting point about the round-pads-oval-hole thing. That's an interesting design - in THEORY it will add more bass at the cost of a reduced soundstage vs the same round pad with round hole.
I wonder how much room is left for your ears in the round-pads-oval-hole design. For example, I have 2 pairs of Philips SHL3300. It's designed for a 100mm round pad, but oval pads such as the Brainwavz HM5 also fits. On one of my SHL3300 I have 100mm round pads, and the other I have Brainwavz HM5. The INSIDE dimensions of each is as follows:
100mm pads = 56mm diameter ID
HM5 pads = 50mm width x 70mm length ID
My (average size) ears are 60mm long. Both are comfy, but you can obviously guess which pad fits my ears better.
It appears like the Lasmex is a hybrid of the 2 designs - a round pad with oval ID. Like merging the more natural shape and generous ID of my Brainwavz pads with the OD of the 100mm pads. Brilliant!
