These are Panasonic high-resolution audio compatible in-ear headphones. The aluminum body provides a high-quality metallic feel, making them look great as earphones! I bought these a few years ago and used them with my iPhone, but I haven't used them recently because I bought wireless earphones. I checked to see if they still work before listing them, and they sounded great with no distortion or other problems! After checking, I also cleaned them with alcohol, so you can use them right away if you purchase them!! As a bonus, I'll also include an Apple-certified Lightning to 3.5mm headphone jack adapter, so iPhone users can use them immediately!! #Panasonic #Panasonic #Earphones #WiredEarphones #HighResolution #HDE5M
