Cord design seems too short for use with portable players

1 agrees

Cord texture sticks to clothing and tends to pull earbuds out of ears

1 agrees

Asymmetric cabling design is odd and tends to get in the way more than make moving around convenient

1 agrees

Cable extension is too long and makes up the bulk of the cable; without it they are essentially unusable

Build quality is somewhat shoddy, rubber components degrade quickly, Denon badges fall off easily
