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.

Our Verdict

6.4 Mixed Usage

They perform moderately well in most use cases and make for decent everyday headphones.

Pros
  • Great audio reproduction.
  • Minimal leakage.
Cons
  • In-Ear design may be uncomfortable for some.
  • Poor noise isolation.
6.7 Neutral Sound

Average for neutral listening. These headphones have a decent audio reproduction but the closed back in-ear design lacks a little openness for neutral listening.

6.3 Commute/Travel

Average for commuting. They're small and have a compact design, but their active noise isolation is weak and may not be sufficient for loud, noisy environments.

6.8 Sports/Fitness

Above average for sports use. They're stable and are also small enough to carry around on your person everywhere you go.

6.3 Office

Average for office use. They won't block the chatter of a busy office.

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-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.

Comes with a drawstring pouch that will protect the headphones from damage, does not add much bulk and is small enough to fit into a pocket. Sadly, the headphones will not be protected from physical stress and hard falls and could get damaged by water as the pouch is not waterproof.

Design
Build Quality

Build quality is decent. The control module is portable and not too cumbersome. The in-ear buds and module are made out of moderately dense plastic that feels somewhat durable, but the cabling is relatively thin and could have been rubberized to prevent wear and tear from damaging the cable easily.

Design
Stability

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.

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.
