From Headphone Bar: Akg k550 full sized, closed back headphones. These are akg's reference closed headphones, meaningthey are their best closed back model and are tuned to provide a highly accurate sound, suitable for mastering or music enjoyment. AKG k550 provides tight, quick deep bass (no boosted or bloaty bass here), very clear midrange and excellent extension in the treble, with tons of detail.
With their Real Image design, the k550 provide you a broader, more spacious music experience than almost any other closed headphone near this price. The k550 headphones are slightly more difficult to drive than some other full size headphones, will work fine with a portable device but will sound better with an amp or any decent source, other than a phone. Thick, durable 10ft cable permanently attached.
Heads Up!: In our experience, these headphones are very comfortable, with large earpad openings and little clamping pressure. They do however fit medium to larger heads best - not advised for someone with a small or narrower head shape - they will not fit tightly enough for the pads to seal and provide a good bass response.
