Wireless earphones from Acer, a top Taiwanese precision equipment and computer manufacturer, with charging case and instruction manual. Purchased online and used only three times for morning walks, these earphones are in like-new condition. They are the ear-hook type, which hook over the ear instead of inserting into the ear canal, so you won't get tired even after listening to music for a long time. I bought them because I was interested in the sound of Acer's earphones, and the sound is very mild, not a booming sound, and more European-sounding. - Model Name: OHR547 - Type: Wireless Earphones - Color: Black - Accessories: Charging Case - Package Contents: Instruction Manual Thank you for looking.
