You can barely see the bottom of one hook against the curtains, so I assume there are two on that end as well. And yes, acoustic treatment and placement (*including preamps and converters) most of the time are more crucial then the microphone itself; What happens when those aspects are worked out and it still sounds average?Dont go for the cheap route. But eventually the earbuds could no longer receive audit during phone calls only. Black is basic and eventually I may buy other more colorful belts but I am still buying new shirts & need to determine what other colors to buy. I bought these and one other pair of mary jane style shoes for my daughter for school this year. Ive washed them and sprayed them with Lysol but they still smell foul to the point I dont wear them. they are ok, they are made with a stretchy band. and Id do it all over again. Although, not at first, they were too "floppy" and I remembered reading that the toe strap is adjustable. I haven?t really had an issue with them being too quiet, but I do notice a sound difference if connected to the laptop, iPhone or Roku private listening through iPhone and how the volume is controlled.
