12cm Lightning adapter featuring the Conexant cx31993 chip, achieving high-quality audio with 384kHz 32bit support. - Type: Lightning Adapter - Chip: Conexant cx31993 - Audio Quality: 384kHz 32bit - Length: 12cm - Weight: 12g Thank you for viewing. I used this adapter a few times at home, but I'm selling it because I no longer need it after changing devices. It's lightweight and easy to handle. I think it's useful for listening to good sound simply or when more output is needed. I used it with Beyerdynamic headphones. Thank you.
