I recently purchased a Clear Tune Monitors (CTM) Wireless Cable w/Mic to use with my VS-3 IEM's & wanted to give a quick report to the community. First, CTM is currently offering them @ 50% off the usual $100 price. They operate on Bluetooth V5.0. Build quality is good. The cable itself is light & covered in a braided nylon fabric. The control pod is of sufficient size & control spacing that operating it is comfortable. Sonically, the cable is very, very good!
The only negatives are with some of the ergonomics:
1) The cable is a little short. It could be about 6" longer.
2) The audio prompts (both beeps & voice) are too loud.
3) The push of the button to turn the unit off & on is too long.
4) A cover for the usb port would be preferable to leaving it exposed to moisture & sweat.
Still, all-in-all, it's a product I highly recommend at its current price for anyone looking to add wireless to their 78mm 2-pin IEM's.
