I have a pair of AT headphones. A previous pair stopped working in one ear and the manufacturer quickly honored their warranty. Replacement works great.
Always said I’d pay them back by word of mouth since some companies drag their heels, but AT did the right thing.
Don’t buy these they are a Chinese knock off. They sound terrible and feel very cheap. All the writing on the box I received was in Chinese or some language that looks like it. The plug in is also a straight one instead of the 90° one like in the picture.
