So hopefully it stays longer. I think any more would be distracting to drivers. Easy and fast to connect with my smartphone, lightweight and the fit was perfect. I purchased these due to the neck design so they would stay around my neck better. Theyre soft, but not overly hot, and well made. It?s at the knee for me, perfect length exactly how I like my dresses. The Bose is nice, but I?ll keep the extra $100 thankyouverymuch! Assembly was super easy but I did have my electrician hardwire it. The rails didnt come with any instructions, but thankfully, with a little trial and error, we were able to figure it out. I use them to study spanish whail I work.
