@jaywhy not the bose in ears?
If you like them, then go for them. Keep in mind that they are not true IEM's (In Ear Monitors) because they sit on the outside of the ear canal and don't actually go in. That prevents them from having good noise isolation characteristics, which is one of the main selling points of true IEM's
Cue jaywhy vs Dan debate about Bose in 3,2,1...
The issue that I, and the entire audiophile community have with Bose is that they sell overpriced products and market them as being the best. And their marketing works. Whenever anyone asks me for my advice on an audio upgrade and the first words out of my mouth are not Bose, they are very surprised. I too once owned a pair of Bose headphones because I thought they were the best. I gave them away when I got my first pair of Grado's.
Bose doesn't make bad products, they make decent to good products but market them as the best and charge a hefty premium for them, when there are truly superior products out there at a much lower price point.
Don't even get me started on Beats.
