HIFIMAN HIFIMAN Svanar Wireless 【High-Resolution, LDAC】 I purchased this new on Mercari and have hardly used it, so it's practically in new condition. Regarding the sound, the quality is "unbelievable for a wireless device." I'm amazed that such a high-performance DAC is packed into such small earphones. However, as they say it's "all about the sound," the noise cancellation is included but not very strong. For "listening to music," I still think it's one of the best wireless earphones.
