We ordered a 10. Diese Marke passt mir immer gut und immer bin ich zufrieden. I just tried them on & didnt wear them, so well see what they charge. 00 ones that Ive become spoiled. I bought these a month ago I loved them when I got them, last night I accidentally put them trough the both the washer and dryer and the quality hasn?t even changed! They were way to big, so I returned them. Skip to 3:50 and listen about how to insert the stethoscope into your ears. Ive used the headset all day for meetings - so its mostly comfortable; definitely no problem for an hour long meeting but longer than that and Ill on speaker to refresh my ears. Not sure why they went with such subdued light, especially since this is a USB plug in, not wireless, so no battery issues. In the one and a half months I have owned these, I have had to charge them a total of maybe 4 times, this is accounting for ~45+ hours of usage on average per week.
