Deus alternative WS headphones?

Hello, finally managed to buy myself a Deus but since it's very expensive I was only able to get the remote control with 11" coil without the wireless headphones.
Is there any alternative wireless headphones to pair with the remote that works good?
While i truly believe that ws4 or ws5 would be the best, I don't really care to have a second detector in my headphones, I'm not willing to pay 3/400 bucks for headphones.

The volume control is a must but I could survive without any additional control in my headphones and just use the remote but no wires would be super.

I am looking for a cheaper alternative if it exists.
I've read that I could connect WS headphones using the stereo connector (for example deteknix ws headphones) but I've also read these doesn't works good on Deus (muffled sound and delay)

*now I using wired headphones and I like the control box to be attached to the shaft, but theres is no much space between my hand and the headphones connector so I hit the jack all the time (disturbing and dangerous)

Any alternative solution?

Thanks!
