The “Best-Sounding In-Ear Headphone” Is Back

Lauded by Forbes, The Verge, and InnerFidelity, and long rated Head-Fi users’ favorite IEM, the Noble Kaiser 10 returns as the Massdrop x Noble Kaiser 10. Also known as the K10, this model uses the same tuning as the company’s previous flagship, with 10 Knowles balanced-armature drivers per ear. Each pair is assembled and matched by hand, and the precision-machined aluminum housings feature Noble’s updated universal form factor and geometry—now with red faceplates and matte black shells. This IEM is sensitive enough for use with smartphones, as well as portable digital audio players and amps. Available only on Massdrop, and for nearly half the price of the original, it offers a new entry into Noble’s high-end line.

Note: Shipping is free to US members with subsidized international shipping.  For an additional $40, you can add a lightning cable or a 2.5mm TRRS balanced cable.

Praise for the Noble Kaiser 10

  • “These are the best-sounding in-ear headphones I’ve ever heard. They’re the sort of headphones that make you want to listen to every piece of music you can find, just because you’ve never heard any of it sound so good before.” – Simon Osborne-Walker, Trusted Reviews
  • “Noble Audio has crafted one of the best examples of what expensive technology should be. It is exclusive and luxurious, but it's also authentic. The Kaiser 10s have the superior sound and sumptuous good looks to justify their price.” – Vlad Savov, The Verge
  • “I’ve listened to tens of hours of music on these headphones now. I’ve listened to pop, classical, rock, electronic and everything I could find that was recorded with some care and love. The result, almost across the board is, honestly, the best sound I’ve ever heard.” – Ian Morris, Forbes
  • “The Kaiser 10U is uber-transparent: From the deepest bass to the highest treble, the sound remains true. Even compared with my very best in-ear headphones, the Kaiser 10U sounds more accurate and pristine. Bass notes never cloud over or blur together, no matter how deep.” – Steve Guttenberg, CNET
  • “Of all my in-ear monitors—scratch that, of all my headphones in general—the Kaiser 10 is the one I find myself reaching for most often these days; for portable use but also for dedicated listening at home.” – John Grandberg, InnerFidelity

No question about it, the Atlas. They're my dailies and I also have the Solaris and Lyra II. I returned both the Andro and Andro S (the Solaris is superior to both IMO). I was very underwhelmed when I listened to the K10. It has A LOT in common with the Shure 846 without their wonderful low-end texture but do have better treble extension and more air. Still, they're a safe sound and really are a jack-of-all-trades. The Atlas gives me feelings of my 2.1 ch setup. Maybe not to the extent of the Solaris but the fact that a single DD can even get that close is well beyond impressive. The Atlas also hits HARD. It's laughably funny as it's so grin inducing in the best possible way. The sub-bass speed and decay are reminiscent of a woofer from a loudspeaker. If you're at all familiar with that, then you have a solid idea of what the Atlas sounds like overall (for me, this is a huge compliment). They also have some nice treble extensiona nd sparkle but it may be too pronounced for some. I'm treble sensitive and unless I have the volume turned up to 11, the treble is quite composed and lively. Which is wild considering how thick and weighty the Atlas can sound. The treble is just right and cuts through the wall of sound the Atlas can produce. Mids are pulled back just enough but never sound lost. You will never listen to the Atlas and think anything in the mids are too forward or shouty. I'm pretty sensitive to sounds in this range (2k-4k) so I may be a bit biased here and why I ended up returning the pair of Andro's. The (pure silver litz) cable and accessories are better on the Atlas and I find the fitment substantially better. The Atlas just disappear into my ear. The K10 always made their presence known and I had to fight for them to stay still or they would work their way out of my ears and mes sup the seal. The coating is also prone to chipping. The Atlas is 3 solid pieces of stainless steel and look swanky AF. They also have a nice weight and I am quite sure you could swing them and bludgeon any and all enemies to death is the situation ever arose. Either way, this wall of text was just my endorsement for the Atlas. Buy them and don't look back. I know they have caused me to give my other IEMs a whole lot of side-eye these days.
