Best mmcx Bluetooth cable

I’m currently deciding between either the T2 or the se215 for use at the gym, but I’d like to have them wireless with bluetooth.

Do you have any recommendations for bluetooth cables? I was looking at this unless there’s something better…

TIA

I use a Westone Bluetooth adapter at work.

The only complaint I have is that after much use and time traveling they have developed a cosmetic crack above the power button over the course of two years.

But yeah, I would still recommend it for Bluetooth 5.0 and easily 11 hour battery life. The down side, it is more expensive than other solutions that are probably very close in performance.
