Technics AZ100 wireless earphones, with charging case, multiple sized earpieces, and instruction manual. I recently purchased these AZ100s in September, but I'm selling them because they didn't suit me after listening for about an hour. I tried various EQ settings to get them closer to my HD800S, but it seems impossible, so I gave up. Perhaps they shouldn't even be compared... However, as standalone earphones, they were unlike anything I've owned before. The most notable feature is the deep, immersive bass. The high frequencies also come through clearly. And the dedicated app is also great. They've been used for a short period and are in very clean condition. Thank you.
