Duett Headphones - Wireless Bluetooth Headphones with Noise Cancelling, Hi-Fi Sound for Music, Gaming & Travel | Perfect for Commuting, Workouts & Home Office Use

Comfortable and sound good. A bit expensive perhaps. Monophonic earphones a bit difficult to find. I use these with a personal amplifier, so I expect clarity, not high fidelity. They are particularly useful when using a speakerphone, as I have severe hearing loss. I also use it for television so that the neighbors don't complain about the volume.
