Massdrop Nobel X Earphones

Dag nab it! I got so busy last week with the Focal Utopia measurements that I neglected to get the new Massdrop Noble X measured and listened to for a quick report before the drop. Sorry about that.

The Massdrop Noble X is a dandy dual balanced armature driver in-ear monitor. The $249 IEMs come with five different tips, a cleaning tool, and a small cylindrical plastic carry case. A Lightning cable is available separately for $40!

The sound is polite and mildly warm. Bass is modestly boosted and bleeds slightly into the mids. The the presence and low treble area from about 1kHz to 5kHz is a bit low in level giving these cans a laid back and somewhat distant sound. The treble regains sparkle from 5kHz to 12kHz, but drops off in the very top octave reducing the sense of air a bit. Overall, it's a pleasing, mildly warm IEM without any offensive treble issues...and a pretty darn good deal at $249.

My only caution would be for those with small ears or ear canals; the headphone snout and tips are a little on the large size for me. I've got rather small in diameter ear canals and one has a hard turn in it. I did have some troubles with all but the larger foam tip. Too bad, because evidently this earphone is somewhat sensitive to which tips are used. I suggest those interested in a deeper dive check out this Nobel X thread on

Less than 100 left, you can check out the Massdrop here!

Ed Note: My apologies to Noble for misspelling the company name. It's been corrected in the post, but I can't change the title unfortunately.

Hiya Flatline, nice handle you have there. Yeah, they'll brighten up some with a high-Z amp. They talk about it in the SBAF thread I mention.

Btw, it's Noble not Nobel - just saying

In my old age looking back on my career at InnerFidelity, the spelling mistakes will be high on the list of regrets. I fixed it in the text but the headline can't be changed. Apologies to Noble.

I’m not easily impressed when it comes to the audio world because I’m skeptical of how things such as fancy looks, high price tags, and name brand can color what people hear. However, out of everything that I got to audition at RMAF, nothing burned a hole in my heart like the Noble Kaiser Encore. I almost bought the Noble X but I realized that it won’t be a good substitute and I might as well save up for the Encore.
