The JLab JBuds Frames Wireless Head Phones are two small boxes which clip, one to each arm on your glasses. Each has a microphone, speaker, battery, and one push button. You an use just one for mono, or two for stereo. The sound is not as good as Bose Frames sunglasses, but much better than Lenovo Lecoo C8 Smart Sunglasses. These are fine for phone and Zoom calls, but not so good for music.
One problem is that the JLab Frames need a firm large spectacle frame to clip to. There area reversible rubber pads which can be adjuted for different size frames, but they were still loose on my ultra slim titanium frames. They worked fine on a larger pair of plastic frames. These units have the advantage they can be used on prescription glasses, and removed. But in place they still look dorky, and people looking at me on Zoom immediately commented on them. But that was a Mobile Learning Special Interest Group meeting, where dorky is a good thing. ;-)
