Pros: Strong, solid bass impact. Excellent Build Quality.
Cons: Mediocre treble. Extremely muddy mids.
I was impressed with the build quality. The headbands would never break, and the earpieces (aka "Sound Engines") are made of metal. I'll be comparing this headphone to the Grado sr80i and the Audio Techinca ATH M50, which both cost a little more than the Tracks. I used Summertime Sadness (Cedric Gervais Remix) AAC (256 kbps) as a testing song as this song is poorly mastered in such a way that any form of boominess or bass leakage would be detected quickly.
Overall, I was very impressed with the bass on the tracks. It has a very strong, punchy bass, free of any sort of bass leak (which the ATH M50 suffered) or boominess. This is done without sacrificing the quantity of the bass (where the Grado sr80i suffered).
However, the mids and highs is where the Grado sr80i and the Audio Technica M50 would rip the Tracks into pieces. The highs are not as precise as the Grado sr80i and the ATH M50 despite the siblance (ATH M50) or shoutiness (Grado sr80i). The mids are absolutely ABYSMAL. It is very muddy and poorly defined. The melodic line of Summertime Sadness Remix is poorly defined after the drop of the song. Same goes with the bassline. To add salt to injury, the Koss Portapros (a headphone that cost half as much as the Tracks) has better mids than the Tracks. Overall, the Tracks sounded like a bass modded Grado sr80i underwater! Because of this horrendous flaw, I cannot recommend this headphone other than anyone who wants a Beats Solo on the cheap.
Only get them if there is at least a 40% discount.
