In the box, you’ll get Soft pouch, 2-pin airline adapter, single AAA battery included, interchangeable soft earbuds with three different sizes provides a custom fit. Perhaps the design of the model as such and the box are not to your liking, but you cannot deny that you receive several points in favor of the technology used.

The pads are covered with the Comply foam which is very soft and also added in JayBird X3 . In addition, they included 3 different sizes of pads for comfort and greater adaptation of the users. Something good about the location of the cable near the headphones is that it allows you to use the cable above or below the ear, allowing you to use them as you prefer, so you will ensure a better fit and less movement.

In addition, the foam on which the headphones are made, there is no gap between the ear and the earphone, which makes it possible to block outside noise. So much is the blockade that you will not hear nor the sound of the wind, making the users feel relaxed in the music and in the different activities that they realize.

The design of the earbuds is made of a lightweight plastic that presents good quality, and is also resistant. And it reproduces the music well. The biggest problem that users complain about is that the control box is located in the middle of the cables that connect the earbuds and the audio connector. This causes discomfort when in use.

The design of this model does not bring impressive variations, even is very common, so users have been in the task of being very creative to place the box in another position so that they do not bother. The location of the control box usually weakens the cables or causes them to wear, due to the tension that originates when they are placed in all the way. It is compatible with android and other devices but has some compatibility issues of controls with iPhone.

When comparing the ATH-ANC23 model with the ATH-ANC33iS, we see an improvement in sound quality and this model has 13 mm conductors. The bass sound is powerful however it is not overwhelming, it is not as accented as in competing brands.

The high and medium sounds are strong and balanced, and they keep an attractive sound to the users. Audiophiles will be able to hear a slight hiss that occurs when noise canceling is activated, but when playing the music, that sound is not heard.

It happens that when a headset has excellent sound quality, the noise cancellation is not so good, and when noise cancellation is good the sound is not so good. That is why the developers of the Audio-Technica brand designed the ATH-ANC33iS combining in the device both technologies and providing good quality of both characteristics. The noise canceling of the ATH-ANC33iS model is of good quality, however, it does not exceed the models made by the Bose brand.

The ATH-ANC33iS earbuds may disappoint some users a bit because of their quality of finish and a modest performance in the active noise reduction key element when we look at this. If you’re looking for earbuds of reasonable price with good sound quality, then it’s a good choice.
