Pros: Sound incredible
Cons: None for the price
First things first, there is a simple trick that solves all the complaints about the cable connectors - simply rotate each 720 degrees counterclockwise to build up some torque before you screw each one on clockwise. Since you only need to screw 540 degrees clockwise to fasten them, the extra twist remaining in the cable keeps them securely fastened without having to overtighten.
The build is nothing special. Yes the R/L markings rub off. Also the screw placement is oddly asymmetrical. Materials are not luxurious, and comfort is just average (though comfortable enough that I can enjoy them for hours on end without distraction).
The bottom line is that I cannot possibly rate these headphones high enough, because they sound amazing.
Of course when I talk about the amazing sound, I am evaluating them in the context of the price I paid for them: $300. No other $300 headphones I have tried come anywhere close to these.
For starters, the bass is incredible. In this price range, I am unaware of any headphones with this kind of bass extension, impact, and natural sound.
High mids are a touch recessed (less so with the velour pads), yet the mids as a whole remain clear, detailed, and vocals show great depth.
Speed, transparency, imaging: all strong suits.
These headphones absolutely shine with jazz, rap, electronic, funk, rock, and pop. They are a little dark for classical and therefore not my choice there.
Are they the most neutral headphones? Certainly not. The best sounding? For my money, absolutely.
The best $500 I have spent on audio: Modi, Magni, HE-400.
