beyerdynamic Amiron Wireless Product Description These are the best-sounding wireless headphones I've ever heard. The bass isn't excessive, but has a solid power and elasticity, and the mid-range is the biggest appeal of these headphones, sounding very sweet and bright. The high frequencies are also clear, and the soundstage transparency is outstanding. Also, by taking a hearing test through the dedicated "MIY" app, the sound quality is automatically adjusted to the optimal sound for your ears. You can enjoy the best sound without fiddling with EQ settings. I've used many headphones, such as the Beoplay HX, B&W PX7 S2e, PX8, and Master & Dynamic MW75, but nothing has surpassed the sound quality of the Amiron Wireless. If you don't prioritize ANC (noise canceling), this model is undoubtedly the best choice. Furthermore, not only does it have Bluetooth connectivity, but wired connection is also possible. In that case, you can use it without turning on the headphones, and the sound quality when wired is even higher than when using Bluetooth. [Condition] Overall in clean condition, with no noticeable scratches. Operation has been confirmed. [Included Items] Everything shown in the photos. [Reason for Listing] I enjoy collecting headphones and own many. Due to infrequent use and financial circumstances, I am gradually selling them off. As this is a used item, it is not recommended for those seeking perfection or who are overly sensitive.
