The OneOdio Monitor 60s have been announced at a price of well under US$100; nevertheless, the OEM asserts that they are ideal for work such as DJing and even recording songs. They have a "professional monitor" build with faux-leather "memory" ear-cushions for noise isolation and comfort, and is compatible with the 1/4-inch and 3.5mm interfaces.https://www.notebookcheck.net/OneOdio-Monitor-60-launch-as-professional-wired-headphones-pitched-at-DJs-and-studio-artists.652744.0.html
I got better, monitor 80 and tho they are great, construction is a time bomb. If they could improve hw endurance it would be better.
It is still not a planar, if they could build lcd-4 or lcd-5 alternative, it would be worth buying.
