Audio-Technica ATH-ANC33iS Noise Cancelling Headphone


Audio-Technica ATH-ANC33iS QuietPoint Active Noise-Cancelling In-Ear Headphones reduce distracting background noise by up to 90% while offering superior sound.

SKU: ATHANC33IS Categories: , Brand:

Engineered to create a comfortable listening environment in areas with high ambient noise, these in-ear headphones feature a miniature microphone in each earpiece that picks up ambient noise (such as traffic, air-handling systems, etc.). Electronics in the QuietPoint control module create a noise-cancelling wave that is 180° out of phase with the ambient noise. This wave acts like a noise eraser: it cancels out the annoying sounds that surround you without diminishing the audio you want to hear. The result…a peaceful enclave to enjoy the music or movies of your choice.

The Audio-Technica ATH-ANC33iS in-ear headphones also feature an inline microphone and controller for answering calls and controlling music. The mic and controller support smartphones, iPhones, iPads, many iPods & other compatible devices. The microphone has an omnidirectional pickup pattern and it is designed for crisp intelligibility, so your voice will be clearly transmitted without having to speak directly into the mic.

We Say

The ATH-ANC33is combines active noise cancelling technology with a compact, portable canalphone design. Overall comfort is very good, plus being a lot smaller than fullsize active models these are much more portable and convenient for travelling. Noise reduction offered is up to 20dB, which is lower than many other canalphones, but in situations where your main concern is cancellation, not isolation, these are a good choice.

The ANC33is features an in-line microphone and control unit for smartphone users.
