The Audio-Technica ATH-M70x deliver a decent sound but lack the bass and versatility of the ATH-M50x. They're stylish, comfortable and come with a good case but have a slightly weaker build quality than some of the previous ATH-M models. They also don't block noise very well.
- Good instruments and vocals reproduction.
- Comfortable design.
- Poor noise isolation.
- Bass-lacking sound quality.
The ATH-M70x make slight stylistic changes to the overall aesthetic of the ATH-M series. They keep the iconic studio look but have a different headband and ear cups design. They're a bit more loose-fitting and comfortable than the previous models but also a bit less stable. Unfortunately, the headband no longer has a sturdy metal frame, and they don't fold into a more compact format like the ATH-M50x. They come with a good case but are still a bit too cumbersome, to comfortably carry around without a backpack.
The ATH-M70x look slightly different than the rest of the ATH-M series. They keep the overall aesthetic the same, with a bit more silver accents but change the ear cup and headband design. This gives them a more premium appeal but unlike the ATH-M50x they're entirely made out of plastic. So upon closer inspection, they don't look as high-end as they appear to be, which is slightly disappointing considering the previous models are less expensive but seem more durable.
The M70x are above-average comfortable headphones. They're not too heavy or tight on the head. They also have slightly better padding on the ear cups than the ATH-M40x and M50x. However, although the ear cups are large, the opening created by the padding feels a bit small and sometimes touches the tip of the ear. This can cause slight discomfort during long listening sessions, but it's not significant enough to be an issue of concern.
These headphones are not meant for sports. They're not tight enough on the head for use while running or exercising. They will stay in place during casual listening sessions but will quickly fall off your head if used during physical activity. Also, the detachable cable locks into the ear cup. So if the cable gets hooked on something it might pull the headphones of your head before disconnecting.
The ATH-M70X are large over-ear headphones which unlike the ATH-M50x, do not fold into a more compact format. The ear cups lay flat to save space, but they will still be too bulky for smaller bags or handbags. They're too cumbersome, to comfortably carry around on your person, whether they're in their provided carrying case or not.
The M70x have a different build than the rest of the Audio-Technica M line up. The headband frame is no longer metal but a dense plastic that will still be able to withstand decent amounts of physical stress but will not be as sturdy as the ATH-M50x's headband. They're durable headphones just not as durable as some of the less expensive models in the same series. Also, the all-plastic build feels a little cheap for their price.
The bass-light sound quality of the M70x is a departure from the warmer and more evenly balanced M50x. They overemphasize the mid-range and high tones a bit, favoring a crisp representation of instruments and vocals. However, this pushes the instruments a little too forward in the mix, which may sound too bright or sharp for some. Overall, they won't sound as good and neutral as the M50x but on the upside, their Soundstage is quite decent for closed-back headphones.
Poor Bass Range performance. Unlike the ATH-M50x which extends down to 35Hz, the ATH-M70x only goes down to 87Hz. This has a negative effect on the thump and low-end rumble of sound, and also the punch of kick drums and the body of bass instruments.
Decent Mid Range performance. Low-mid is elevated by about 5dB, causing the sound to get a bit boxy. Mid and high-mid are well-produced, although overemphasized by about 2dB making the sound of these headphones slightly mid-rangy.
Average Treble Range performance. Low-treble is elevated by about 4dB, shifting the tonal balance towards vocals/leads. Treble is also overemphasized by more 5dB, especially around 9KHz where there is a 10dB peak. This makes these headphones noticeably bright and sibilant.
Average Soundstage. The ear cups on the ATH-M70x of are a decent size, but not quite deep. Although they interact with the pinna to some extent, it's not enough to pull the Soundstage out from inside of the listener's head. The openness and acoustic space excitation values are also average. The crosstalk detected in these headphones is out-of-phase, but not loud enough to be noticeable.
Good Imaging performance. The phase performance is good, although the phase shift in the Bass range is a little excessive. Additionally, the drivers of our test unit were decently well-matched.
Very good Harmonic Distortion performance. Since humans are less sensitive to harmonic distortion at lower frequencies, the elevated amount of harmonic distortion produced in the Bass Range won't be very audible. The amount of distortion produced in the Mid and Treble regions is very low.
The ATH -M70x are passively isolating headphones. This means they can only block noise by the quality of the seal they create around your ears. Unfortunately, although the seal is decent the level of isolation it provides is not enough for loud environments. They won't fair well on noisy commutes and will be unideal for flying. They also will leak at higher volumes so they may be distracting to the people around you in quieter settings.
Poor isolation. The passive isolation provided by the ear cups performs well in the treble range. They consistently provide more than 20dB of isolation. However, the overall amount of isolation in is only about 10dB the mid-range and 0dB in the bass range.
Average leakage. The significant portion of the leakage is between 2KHz and 8KHz, which is not too broad. The overall level of the leakage is also about average.
