Audio Technica ATH M50X vs Onkyo ES-CTI300(BS)

The ear cups and pads are able to keep the sound in and block outside noise. These are suitable for a noisy office as even low volume music is enough to drown out those noisy office mates.

Audio-Technica finally updated the M50's built in cable to a detachable cable. The M50x even comes with three cables, a 1.2 m - 3.0 m coiled cable, a 3.0 m straight cable, and a 1.2 m straight cable. None of the cables have in-line controls though.

The ATH-M50x are great sounding headphones with a sound that may fall in the neutral category, but with very slight boosts to the bass and highs; a slightly V-shaped sound. The bass is full and has a lot of power. The sub bass has a hint of elevation though, which can make the bass sound a bit loose on hip-hop or EDM tracks. The mids are fairly neutral with no elevation. The highs are also slightly elevated, which does not add harshness but instead gives the sound a shimmery and detailed feel.
This sound signature of the M50x makes it versatile. It is neutral enough for monitoring use, yet also has just the right qualities to make it a great choice for enjoying music.

This feature helps provide comfort even with long hours of use, and since memory foams does not shrink overtime, you would be able to experience the same comfort for years.

These headphone's earcups can turn 80°, which is quite handy: they can be folded flat and makes it easy to pack them during travels.

The clamping force produced by the headband is just enough to keep the headphones in place,
gently pressing the soft memory foam ear cushion against your ear providing maximum comfort even when used all day.
