Hi all, I want to leave a testimony for those interested. A couple of months ago I wanted to buy a headphone for music. I didn't want to spend too much money on it, in fact, I wanted to be lower than $50. So, you may realize how hard is to get something really good at that price range. I began to read reviews of many headphones and after 3 days, I had decided one. Audio Technica ATH- M20X. People, I really advice everyone who be looking for a good pair of inexpensive headphones to go for it. Incredible sound for the price. I have been listening headphones most of my almost 40 years in the audio world, Grade, AKG, Sony Reference, Sennheiser, etc. I want to say that this Audio Technica is so good sounding that I don't think anybody could be unhappy with it. I paid $43.00 free shipping, an steal if you value the joy of listening to them. Hope someone gets my advice.
