A:AnswerYes it can, contact Bose. Probably just a wire at the y splitter or at the ear piece. If you know someone who solders, you might be able to get them to rewire it for you.
A:AnswerWhen I had the older model in 2007, I needed a replacement for a lost one and I went into a Bose store, and got 4 ear-tips for $7. They are all the same size though. Hope this helps!
A:AnswerI wear them at work and have never had an issue with sharing my music... the sound stays in my ears only. I would think if you cranked the volume then the sound would travel, but I have taken them out to talk, left the music playing and not had an issue.
