The thing about being a portable audiophile is that you have to put a lot of trust in online reviews. It’s hard to get the full experience testing out a pair of cans in Best Buy and often places like that are lacking the vast majority of most high-end models.
CCG writes - "The Sineaptic SE-1 is quite a remarkable headphone. It's an amazing first product from a new company. It does some unusual things like offering Bluetooth and 3.5mm inputs in an audiophile headphone. It offers an incredibly unique driver design at an amazingly low price. Its build quality is fine, but not spectacular, as long as you get one with no production issues."
All in all, I’m a fan of the Cleer Arc II.T They’re brilliant at what they’re advertised for: being the ideal running companion.
Serious about your headphones? Noise-canceling is the way to go.
