Headphone Review: Moshi Moonrocks, take two

As promised, this is our second look at Moshi’s Moonrock headphones. You can read the first review here.

Moshi is a fairly unknown company, but has been expanding since 2004. They have recently endeavored upon the headphone market with their latest creation, the Moshi Moonrocks. Moshi strives for the best in design, looks, and usability. Design, looks, and usability may be good to have; however, when it comes to audio equipment, it’s the sound that matters most to people. The Moshi Moonrock offers listeners a simple design, good audio quality, questionable build quality, amazing comfort, and a bang for their buck.

These headphones were sent as a product sample, free of charge, by Moshi.

In The Box

  • Moshi Moonrock Headphones
  • Moonrock carrying case
  • 3 Sets of Silicone Hybrid Injection tips

The Moonrocks come with the headset, 3 sets of tips, and the Moonrock case.


Moshi took to a really simple Apple-style design when they designed these headphones. The Moonrocks have a really intuitive and and simple look to them. This design beats Apple’s when it comes to simplicity.

Each earpiece is composed of plastic with a rubberized, circular tip on the end. The design really has nothing special about it. It is available in 2 colors, black-red and milky-white. The plastic is not visible while in your ear, so only the white, or black, rubber circular pieces are visible.

The Moshi Moonrocks have a really simple shape to them.

The case is also part of the entire design as well. When the headphones are in the case, they disappear from view (unless you have the black and red ones, then the red wire shows). The case itself is a design statement. Everything seamlessly blends together with these headphones.

The case is in the shape of a “moon rock”, or what you’d think one would look like.

The cables on the headphones are thicker and really well designed. There is no adjustable Y-split, which is always something that could be of use for the people who use them. The remote also has a very tiny button that is harder to press. Both of these are really minor issues though.

This is what the Moonrocks look like in your ears. As you can see, they can be worn over the ear or under.

The overall feel of the headphones feels very cheap, but the design itself is very simple. It’s not something to look at twice, nor will it turn eyes… Unless there is someone asking, “what the heck are those circles in your ear?” I actually really like the design of the headphones.

Design ★★★★½

Audio Quality

The audio quality of these headphones is what I was most interested in, being a newer company to headsets, I was really curious to what these would sound like. When I first got them, I put them in to get a good seal and then noticed the really ‘laxed warm sound. The bass was too overwhelming, but a little boomy and a tiny bit muddy and intruding at times. The Mids sounded a little recessed. The treble was really light and crispy, sometimes it was absent. I let them burn in for 50 hours after that to let the signature settle in.


The bass is where these headphones were the best part about them for me. The lows are powering, sometimes too much, and deep. The bass is not that punchy though; it can seem unnatural at times. The bass has lots of impact in the low-mid range, it is sometimes too much impact, but that rarely happens. It is textured and feels really nice. Even with all this power, the bass doesn’t really intrude with the mids and highs. The bass can tend to be muddy in faster-paced songs. The bass is calming, but still dominant; it’s a weird combination that seems to work well though. The lows on these headphones are really well textured and just fun to listen to.

Bass ★★★★


The mids seem recessed compared to both the treble and the basIs. Still, they are clean, clear, and audible. The mids aren’t my favorite, they aren’t harsh or anything, there are no major peaks, they’re nicely done. There isn’t anything special about them, but that isn’t a necessity. They do tend to disappear every so often, but are still there in the deep background. They are also not as detailed as I’d like them to be.

Mids ★★★★


Slightly recessed compared to the bass, but forward compared to the mids, the treble actually is pretty audible most of the time. However, I find that they are recessed too much most of the time. They are softer than the mids and do have some extension, but not much. They real don’t have the special sparkle associated with them; they sparkle, but not brightly. Similar to the mids, these highs aren’t as detailed as I’d like them to be. The treble isn’t harsh in any way, they still feed to the relaxed nature of the Moonrocks since they are really rolled off. The highs can be good, but nothing more.

Treble ★★★½

Noise Isolation

These headphones have really great passive noise isolation from the outside world. You can put them on and they’ll actually decently isolate sound. They are definitely a good step up, and the deep insertion helps plenty to make sure you hear your music, not your obnoxious friend next to you. Will it isolate everything, no, but it does a decent job at it.

Noise Isolation ★★★★


The microphonics on these headphones is pretty big and audible when worn down. Fortunately, the design does work with an over-the-ear insertion. Doing this removes the majority of microphonics. There still is some, but most of it is muted after wearing them over the ear.

Microphonics ★★★★

The sound of these headphones have a bass heavy, but not intruding, ‘laxed sound. I like it, it’s just enjoyable and soft on the ears. Overall, they still have pretty good quality to them. The signature would be be described as very warm. These definitely aren’t an audiophile’s headset as they are lacking details and aren’t flat, but I can still see an audiophile enjoying this type of signature that is relaxed in nature.

Audio Quality ★★★★

Build Quality

These headphones have mixed build quality. The structure of the headphones feels fine, but the build is nothing special. Moshi could have done a couple more things to improve in this area.

To begin, each earpiece is composed of plastic. This isn’t the thick plastic that I like. It feels cheap and thin. They seem very easy to crush; thankfully the case should be able to protect them from this, so I’ll give Moshi the benefit of the doubt here. Still, they do feel a little cheap, but the case helps. Each nozzle has a mesh cap that is made of metal. This prevents dust and debris from getting into the driver. The headphones also suffer from driver flex, more on that in comfort quality, which can damage the drivers in the long run.

The tip of the nozzle is composed of a metal mesh that protects the driver from the environment.

Leading out of each earpiece is a strain relief, and a tiny one if you want to call it that. These reliefs look puny and don’t look like they can handle the stress that these can take. So don’t yank by the cable, instead, when removing the headphones, use the circular area. One thing I don’t like is in the directions, it tells you to pull on the cable to remove them from the case. This scares me a little as the strain reliefs don’t look like they can handle this.

The case protects the headphones from drops and falls. It also protects the drivers and cable from dust, debris, and other environmental factors. The case is really nice, I’d recommend using it with the Moonrocks, whats a moonrock without the actual moonrock anyways?

The remote is another area I saw improper build. My remote only works when it is at a certain angle. I have to twist it for it to work sometimes. It really makes be question the build quality of the headphones. The problem has fixed it self somehow, but does occur once in a blue moon now.

The cables themselves are as thick as the SuperFi 4s. This enables them to be flexible, but durable at the same time. The cable can tend to tangle every so often, even when removing them from the case which has a built in cable winder. The Y-split is nice and thick. The cable terminates at a headphone jack.

Straight headphone jacks have never been my favorite. I firmly believe that angled headphone jacks should be the standard. The Moonrocks have a straight headphone jack. Even though the jack is straight, it’s still very flexible though, which helps out. The rubber is also a lot thicker which helps out a lot. The gold plating also helps from corrosion. The headphone jack is durable, but still could use some angling in it.

The headphone jack on the Moshi Moonrock is straight and composed entirely of rubber.

The build quality is a love-hate type of deal. I like some of the build, but hate others. The overall quality is average, but the remote being built weirdly, maybe I just got a bad copy, but the 2 year warranty does help though.

Build Quality ★★★½

Comfort Quality

Comfort is something that is rarely heard of when it comes to in-ear monitors. The Moshi Moonrocks, however, excel here. They are extremely comfortable to wear, to insert, and take out. I had no problems putting them in and taking them out repeatedly. It’s really easy to get a good seal with them and keep the comfort as well. I was really pleased with the comfort of these headphones.

One major problem that did pop up for me was the seal. These IEMs are not vented, so a little phenomenon called driver flex occurs many times. Driver flex is caused by the driver of the headphone moving because of the seal created when you insert the headphones. This moves the driver at an angle in which the sound doesn’t hit your eardrum, or hits it at an angle. The result of this phenomenon is tiny sound, or no sound at all. The way to fix it is to try to equalize the seal, since there is no vent, there is no place for the pressurized air to go, therefore, you have to keep trying to reseal. This, in the long run can also damage the drivers.

If it wasn’t for the fit issues, I’d be able to give the Moonrocks a perfect five in this category, they are very comfortable to wear, but since it’s hard to get a seal it deducts a star.

Comfort Quality ★★★★

Value For Money

The Moshi Moonrocks are available to purchase direct from Moshi and on Amazon for around $40* a pair. For what you get, they are actually worth the money. The Moonrocks offer a balance of comfort, sound and style with some mixed build quality.

The Moonrocks offer great comfort that is not going to fail. Besides the comfort and good sound quality, the Moonrocks also have the great design in the case that just works. Moshi also puts a unique sound signature on these headphones that is really nice. I really can’t think up of a pair of headphones that had a signature that was like this.

Moshi built a remote and microphone into the Moonrocks. This allows user to take calls and control music on the go using Apple’s Morse code style of input they created for the third generation Shuffle. That is a great value for any iPod, iPhone, or smartphone user.

The remote and mic on the Moonrocks allow you to control your music.

The thing that is questionable that would cause me to turn away from these is the build quality. This is the gamble you’ll have to take when you purchase these.

Overall, the headphones are still worth a go, especially if you are looking for a nice relaxing sound to come out of them. The signature won’t work for everything, but I really like it.

Value For Money ★★★★½

Final Thoughts

The Moshi’s are not made for audiophiles, but even an audiophile can find themselves enjoying the relaxed, laid-back sound of the Moonrocks. The design is brilliant and integrated perfectly with the case that seamlessly makes the whole thing one with itself. The comfort is really unsurpassed and unseen for IEMs. The only main problem is build quality. The Moshi’s are definitely a great pair of headphones if you want to just lay down and chill.
