For sale: ATH-CKR70TW BK wireless Bluetooth earbuds, black. I received these through the Hometown Tax program and used them for a while, but haven't been using them lately, so I'm putting them up for sale. They charge without issue, but I haven't assessed the battery degradation. I've confirmed they connect and work with my iPhone 12 mini. In my personal opinion, they are small but deliver clear sound with a crisp, true-to-the-original sound. Even those who prefer a "V-shaped" sound signature should be satisfied with equalizer adjustments unless they are very particular. - Brand: audio-technica - Model Name: ATH-CKR70TW BK - Type: Wireless Earbud Microphone - Connectivity: Bluetooth, USB typeC - Color: Black There is no history of water damage, and the main unit is clean. The charging case has some minor scratches. I haven't used any of the included accessories other than the M-size ear tips. Thank you for looking.
