The Audio-Technica ATH-ANC33iS QuietPoint have a typical in-ear design and above-average audio reproduction. Unfortunately, they may not be comfortable for everyone and their poor isolation means ambient noise could potentially ruin your listening experience.
- Great audio reproduction.
- Minimal leakage.
- In-Ear design may be uncomfortable for some.
- Poor noise isolation.
The ATH-ANC33iS' design is not much different from that of other in-ear headphones. They will feel comfortable to those who are already accustomed to the in-ear design but may apply too much pressure in the ear canal for some. The control module is lightweight and relatively compact. The cabling, however, is not very thick and may succumb to wear and tear if used carelessly.
The ATH-ANC33iS have the same esthetic as the ATH-ANC23, with a few minor color differences. They have a very common design with an all-black color scheme. The control module isn't too bulky, and the in-ear buds and tips are also all-black and engraved with the Audio-Technica logo on the back.
The ATH-ANC33iS are as comfortable as you would expect for an in-ear design. They offer a variety of tip sizes and an additional memory foam tip that provides slightly better stability once in the ear. They still, however, apply pressure within the ear canal, which may be uncomfortable for some, especially during long listening sessions.
Button functionality and placement is average. They offer decent functionality with call/music and volume control, as well as a simple switch to enable noise cancelling. However, the buttons feel poorly laid out; the call/music button being too far from the volume dial is slightly frustrating.
The ATH-ANC33iS are decently stable in-ear headphones. They fit deeply into the ear canal and don't quickly fall out your ears during moderate physical activity. However, the control module and long cable can easily get hooked on something and pull the headphones out of your ears. They also don't have any unique tips to help maintain a stable fit which makes them unideal for high-intensity exercises.
The ATH-ANC 33iS are very portable in-ear headphones. They will easily fit into a pocket purse or bag and do not take much space. However, since these are noise canceling headphones they come with a control module that makes them a little bigger when folded, than regular passive in-ear headphones.
The ATH-ANC33iS have a surprisingly good audio reproduction. They sound sufficiently bright, instruments and vocals are well reproduced, and bass packs a decent punch. However, the bass extends a little too much into the mid-range, giving these headphones a slightly boomy and boxy sound. Some tracks may also sound a bit too sharp because of the odd spike in the high frequencies.
Good performance. We had difficulty matching the response of the left and right ears. Not only does the right ear perform differently than the left, but was also about 5dB quieter than the left channel. The bump in high-bass, which continues into the mid-range, will add boominess to the sound.
Decent performance. The major issue here is the bump covering the entire low-mid and some of mid, which slightly overpowers the bass. The overall effect is a boomy and boxy sound.
Decent performance. Again, like in the bass region, there was a significant mismatch between the left and right drivers. Also, the bump around 9KHz makes these headphones a little sharp sounding.
Good distortion results. Both the 90dB SPL and the 100 dB SPL results are within very good limits.
The ATH-ANC33iS do not deliver a well-isolated listening experience. The noise cancellation is weak, and the passive isolation from the seal of the in-ear buds is passable at best. They shouldn't be your first choice to cancel out the rumbling ambient noise of a train or the chatter of an office. On the upside, they don't leak much overall but do let some high-frequency sounds, like that of hi-hats, escape.
Poor performance. These headphones do poorly throughout the frequency range. The passive isolation provided by these in-ears is especially poor around 5KHz. The active noise isolation, although effective in the bass and mid regions, performs consistently below average.
Average leakage. The majority of the leakage will be in the treble range, which is typical of in-ear earphones. However, the loudness of the leakage is unusually high for an in-ear design.
No compatible app.
