The highs are great with just the right amount of sparkle without being sibilant, the mids are very forward and you can hear vocals very clear and upfront (though a little cold), the bass is. It’s high quality metal and there is no issues lining up charging components, you just sit it on. Get yourself some leather oil or cream (i prefer Obenaufs) and clean em now and then and these boots will always get noticed. Ive had a pair of Birkies for three years, worn outdoors in the summer and indoors all year round and have found them extremely comfortable (the footbed moulds to the shape of your foot) and warm in winter - in fact warmer than fur lined slippers! Buy the 12 x 1. Im afraid theyll stretch out and be sloppy on my feet. I used my last pair for over 3 years, before my mom lost it on a trip. Replaced my old one with this and comfort was back to its original form. But the sound quality of these headphones is great. They are REALLY fitted, so beware if you have wide feet.
