Audio-Technica ATH-M40x vs Onkyo W800BT

Sound signature is quite accurate, almost flat. Bass is much more controlled instead of boomy, while there is a slight elevation on the highs, resulting in extra energy and detail up top. These offer a nice middle ground between a fun sound and a more reference/analytical sound signature. This sound quality makes the headphones quite versatile as music enjoyment headphones or studio-use cans.

The M40xs feel solid and are known to be quite durable. The plastics used in the build do not easily flex or make creaks, giving the impression that these can last quite a long time.

The over-ear, closed back design along with the thick pleather ear pads can block out quite a lot of ambient noise, and will help users to focus in on the music. These make the headphones great for travel or for mixing/monitoring use.

The headphones come with a straight cable and a coiled cable, making them useful in the studio or while walking.

Instead of being bloated and overpowering, the bass is punchy and fast so while these will not be able to produce a lot of rumble. Thump should be satisfying for most users. The highs are nice and airy with a lot of detail yet never become harsh, so these are not fatiguing to listen to. The mids sound very natural and jump out just enough to make vocals and guitars very easy to hear and appreciate.

These should work best for more vocal and instrument focused genres like jazz, rock, classical and the like. Bass heavy tracks will still sound good with these, though these headphones will not be able to give the deep bass that bass lovers will be after.

The carrying case has an internal battery, and with a full charge, can supply the headphones with 5 full charges on the go.

The soundstage that these produce gives the music an open feel with good instrument separation. This quality will help give the listener an immersive music listening experience.
