The swivels on these work perfectly. Ein Herausrutschen des Gerätes bei genügender Klemmung (einstellbar) halte ich für höchst unwahrscheinlich. It seems almost pointless and perhaps even a product that shouldnt have come this way. The Good- Sound quality is good- Comfortable, you can wear these for most of the day. Plan on buying another pair in a different color just to have a back up pair in the future once I wear these ones out. So I decided to spin the money for this headset which had good reviews. They?re not designer quality shoes, but they?re really attractive and they?re worth what you pay for here. I only noticed the mids when I compared side by side with the Klipsch KMC 3, again though like others, this speaker cannot beat the JBL in overall loudness and clarity. Just one slight problem with these, the strap across is much shorter than previous sandals so I have had to use the last hole in the buckle and the leather end just fits inside the buckle. I wish I could find boots that will hold up to hard work.
