Disclaimer: I purchased these CIEMs from the Noble website at the price of 1850$, before the markup. I do not have any interest conflicts or relations with any audio parties, and am writing this review as an individual enthusiast. This review is to share my early impressions of these CIEMs with the Head-Fi community.

All listening is done with the Astell&Kern AK240 as depicted.



Ever since I started this journey, I have been dreaming about the CIEMs that I would get once I felt like the time was right. And boy, did these CIEMs make my dreams come true.

Pros:
Fabulous sound that I have ran out of superlatives to describe.
Wide soundstage.
Great build.
Did I mention fabulous sound?

Cons:
Expensive. But definitely not exclusive to Noble.
Long build time. (Also not exclusive to Noble)
People might make mental health institution recommendations after learning about your purchase.
Poorly mastered tracks become glaringly obvious.

Purchasing experience:
I put these headphones into motion around mid January, where I sent my impressions to Noble. The Noble CIEM team started building my earphones, and I received the package in mid April. However, the left ear was too large and I had to send them back for a slight remodel. I received the remodeled earphones in early May. Throughout this experience, the Noble team was fast to respond to my inquiries. I would like to thank Sunny, Nancy, Brannan and Mr. Wizard for their care of their customer. I am impressed by the Noble team.

Accessories:
The accessories were minimal for a purchase of this price tag; a wax cleaner, a cleaning cloth, a hard pelican case that is definitely too big to carry around but apt for shipping, a soft pouch case, two Noble bands that are too tight to wear around your wrists and two Noble stickers. Oh, you also get a shiny owner's card for all your troubles!


Build:
The build of the headphones are phenomenal. These things are built like a truck; I definitely don't see them breaking anytime soon. The only thing I have to criticize are the cables; they are normal cables, and again, some might expect more at this price tag. I expect to find some nice aftermarket cables after trying them out. After the remodel, the fit is exquisite. These things really hug my ears. The ear pieces are a bit larger than I expected, though they will not protrude out of your ear canals.


Art:
I requested the red and black carbon fiber, with a personal design on one side and the Noble sign on the other. The product is stunning and looks better than I thought it would, though it would probably be even more beautiful had I chosen the Wizard design. (400$ mark up for that option!) I would also like to note that there is no extra charge for choosing fiber or other designs, unlike some other CIEM manufactures. I like this, as the compound cost of artwork CAN creep up on you if you aren't careful with other companies.


Sound:
I love the sound. I think Noble have produced a landmark audio product; the tone is lush and beautiful, highs, mids and lows come through as they should; the sound is analytical yet enticing. The soundstage is huge, the details captivating, the depth blissful. I really think Noble have found the perfect balance between analytical and musical; put in any genre, and you find yourself thoroughly enjoying the music. These earphones are responsive, tight and absolutely critical of your mastering quality. Bad tracks are glaringly obvious and can become hard to listen to, while you will find details you didn't know existed in masterfully recorded scores.

Summary:
The Noble flagship proves to be CIEMs that is one of the best in the industry. These CIEMs will make your love your music library even more than before.

End game CIEM.

I purchased this player to upgrade my Fiio X3 and the Colorfly C4. Both good players in their own rights, but out-shined greatly by the AK240. As one of the most powerful player at the time of purchase (2015) and maybe today (2017), the AK240 packs punch, quality and great UI into a relatively small package--at a price. 
 
Of course, Iriver products are known to be quite costly, but the 2,500 price tag will probably shy off most listeners. Is it worth it? I would say so. The sound quality and UI are both fabulous, and the battery life will last you for the day unless your earphones are glued to your ears. 
 
At the time of this review, however, AK have already launched their new flagship--the AK380, which comes at an even heftier price tag. For now, the "budget" AK240 still holds its own as one of the best players in the market. 
 
Bottom Line
The AK240 is a luxury product and doesn't disguise as otherwise. Then again, all Audiophile products are somewhat luxury products. If you love audio and price is (somewhat) an object, then go for the AK240. If you have really deep pockets, the AK380 is just waiting for you in some Amazon warehouse.

 
SO, lets get on to it. The MTPC's are a pair of IEM's that are in a very akward position. It is quite pricy and rejected by the "purist audiophiles" that dislike the brand of Monster, due to the Beats Phenomenon; it is not picked up that well by non-audiophiles due to the muddy SQ a bad amping process can give it. But these are actually a hell of a pair of headphones, and Monster is a company that has earned my respect.
 
So these were my first "Audiophile" grade headphones. I had been fine with my Beats Tours prior to this purchase, and I never realized on what I was missing out. Once I purchased these, there was no turning back. I was blown away by how good headphones could sound. Now I own the HD600's and the W40's (Update: Now the K3003). I enjoy both greatly, and I am parting with my Turbine Pros because I am selling them to a friend.
 
Starting by using the IPT, I was not aware of what the MTPC could achieve. True, They weren't THAT BAD without amplifying as some of you say, but they certainly could not compete with the experience that the Fiio X3 offered me.
 
I used these headphones carefully, and I was very happy that it lasted me a long time. I like the warranty (lifelong) and the free once-in-a-lifetime exchange for a total new one. A TOTAL NEW ONE. Thats how confident they were in their build quality. (or unconfident? lol )
 
I am not to judge the SQ too heavy here, though I like it. I fee like dancing every-time this headphone is being worn, which can be a bad thing (because some of the music I feel like dancing to is actually soft and sad songs). That being said, this is definitely a fun headphone, with heavy coloring but very good sound quality.
 
Highs: Highs are fine. They are THERE, but thats it. Its good highs, but not where the strength of the MTPC are at.
Mids: I enjoyed the Mids the most. I feel the MTPC's have really done a good job to bring the sound into your ears.
Bass: GREAT BASS. Nuff said.
 
Bottom Line: If you want a headphone that is often underlooked and misjudged because of it's brand, and like hipp-pop music with heavy bass and good mids, go for the MTPC. I loved these headphones!
