        Comments about Audio-Technica ATH-CKX7 SonicFuel™ In-ear Headphones:

        Have multiple sets of Audio Technica gear, Dad loves going for long walks and has been asking for a set of ear buds. I love my pair and the ear tips really are handy as they work really well not coming off easily.My ears seem very avg in fit the fitments that came with the earphones worked perfectly. For the old man he needed large tips with small ear tips. I was able to get him a perfect fit as they include all size tips and sets of ear tips. Also they include a comply foam tips while good it is not meant to last as long as the Silicone it is great for noise isolation. Overall the sound coming out of these are good and the accessories helps make these some of the most comfortable pair. I wish it had a little more base i can only compare the bose ie2 as that is the only other high end ear buds i have.

        Overall very satisfied and love Audio Technica will recommend to others.
