I really cannot stress enough that the Zeus-XR that was released a couple of years ago is really a true Top of the Line earphone. Changed to a better silver-based cable and better DAP-source that are released in recent years, you can really see how it scales and does not bottleneck at all. Although it is now discontinued and unable to be found in catalogue on Empire Ears website (correct me if I am wrong) and it is only available in Massdrop's version at a bargain of a price. Even with extensive A/B comparison with recently released earphone such as Wraith, I don't see Zeus-XR hiding its face under the glory of newer releases. Zeus is still shining and I don't see myself having to upgrade because the Zeus-XR fights off my itch of getting new earphones. I even compare the Zeus-XR with my Utopia headphones just for fun, and they really do trade blows in some aspects. Really can't thanks enough to Empire Ears that they produce such a gem for my ears.
