Learning never ends and the gr10 is a result of a constant desire to look at designs and materials and improve upon them. Improvements upon the single armature design found in the gr8 are now in the gr10. A higher level of precision and new materials allows for the performance of the gr10 to add frequency extension in both the higher and lower ranges as well as lowering distortion. The result is an even more faithful experience to the recorded musical event.

A proprietary wide bandwidth moving armature design provides the listener with unsurpassed performance. Small size allows earphone to nestle well within the ear canal, maintaining an excellent air seal for improved bass and reduction of outside noise without causing discomfort.

Headphone Design

Headphone Type

Headphone type refers to the construction of the headphones.

Around the Ear means that the headphones wrap around the ear to provide a secure fit. This is most often seen in active and sports headphones.

Around the Neck means that the headphones wrap around the neck. This is also seen in active and sports headphones.

Earbuds means that the right and left sides of the headphones are separated and will fit securely into the ear. These are small, compact, and user friendly.

Over the Head headphones mean that the right and left speakers are connected with a support that goes over the head and rests on top. This is the typical headphone type.

Earpiece Design

This is the design of the earpieces on the headphones. Some headphones go inside the ear, while others rest on the outside of the ear. This helps you know exactly what type of headphones you will be receiving.

In-Ear: The ear buds go into the ear. Most often, the right and left ear buds are two separate pieces.

Enclosed-Ear: Usually are found on the larger headphones. They rest on top of the ear and have padding for comfort, as well as enclosing the ear to the speaker. This type of headphone helps to filter out surrounding noise.

On-Ear: This type of headphone involves the speaker sitting gently on the ear without going in the ear or sealing it off.

Specifically For
Some headphones can use an IR Transmitter in your vehicle, while some can be plugged into your media device and be used on the go or at home.

This is the lifestyle that the headphones are designed for. Each style has unique features that make it perfect for particular people.

Designed for those that are active. These headphones are made to stay in the ear during workouts. Whether you frequent the gym a lot or go running outside in the fresh air, these active style headphones will be your best friend.

Disc Jockeys (DJs) require a special type of headphone that can meet their professional needs. These headphones are durable, loud, and will often allow for one ear listening.

Fashion Enthusiast:
For those that want to make a fashion statement with their headphones. Not only are these headphones designed with great sound quality in mind, but also great looks!

Music Lover:
These headphones are made to sound great. They are designed to produce rich, brilliant sounds that will play your music in a manner that the artists would appreciate. These headphones are for those that love music.

Musical Production / Recording Artists:
You're a music creator. Whether you're producing and mixing it down or in the studio recording yourself, you need a pair of headphones that will reproduce the music perfectly without any coloration. Look here for reference quality studio monitoring headphones.

Headphones need to be affordable and durable to keep up with the student lifestyle. A variety of styles can be considered a pair of student headphones.

Those that often find themselves on planes or on the road a lot. These headphones are compact, lightweight, and have a portable design. Some of the headphones in this lifestyle will feature noise cancellation technology that will help shut out outside noise.

Acoustic Principle
The basic design of the headphones. There are 3 different types: Open: Have ports that allow air through the back of the diaphragms, enabling the headphones to sound like the music is coming from an outside source. Closed: Completely sealed and have no air passing through the diaphragms. Sounds like you are in a closed off room. Semi-open: Have slots or ports in the back of the cup and are partially open. This allows for a mixed sound between an open and closed headphone.

General Features

Noise Reduction technology removes unwanted noise from a signal. Background or ambient noise can be removed to produce clearer speech and enhanced hearing. Typically these Active Noise Canceling (ANC) headphones are powered and use batteries to activate the noise canceling technology. Also referred to as Noise Reduction or Noise Cancellation.
Headphone Connection
This is how the headphones connect to the audio source.

Corded means that the headphones use a cord to transfer the audio signal.

Wireless means that the audio signal is transmitted wirelessly to the headphones.

1/4" Stereo Jack Adapter
Some headphones will come with a 1/4" stereo jack adapter to connect the usual 3.5mm jack to a 1/4" stereo plug.

1/4" Stereo jack is a larger audio jack that select electronics have.

Volume Adjustment
Volume Adjustment means that the headphone (independent of the source) can adjust the playback volume. Many headphones and ear buds have in-line volume control, which allows adjusting the audible volume from a switch on the headphones cord. Other headphones have a volume knob on the headphone can.
Built-In Microphone
This means that the headphones or earbuds have a built-in microphone. This can be a microphone on the cord, built into the headphone, or even a boom microphone. These mics can be used for music devices like iPods, for Smartphones to make and receive calls, or for gaming purposes.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
20 - 20,000 Hz
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
116 dB
Driver Size
This refers to the diameter of the driver (speaker) on each side of the headphone.
Driver Type
The physical design of the driver in the headphones.
The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
32 ohms
Primary Color
This is the main color of the item.
Secondary Color
A color that compliments the main color of the product.

The GR10 I purchased from Sonic Electronix is my favorite earphone, and I have owned many, including Shure SE535, Sony EX1000, Westone 2, 3, UM3X, 4, 4R and the Etymotic ER4P. The GR10 (a moving armature) is a rare find in the crowded iem world. It has amazing clarity and is still musical w/ quality bass and amazing treble and lush mids. I believe it is the single best iem I've heard. While it lacks the weight/timber that the W4 has, the GR10 has a stunning clarity. At times, they may seem a little bass light but they quality of the bass is very detailed. (In fact, I think the bass keeps getting better the more they burn in.) The mids are great and they have really well extended, controlled highs. The instrument separation is incredible, too. Violin and baroque have never sounded better. They also reproduce piano so well that they make me want to listen to piano solos... something I never do! On folk and acoustic tracks, I've heard actual "space" between the harmony tracks, as if you can imagine where the vocalist sang next to one another.

If they weren't so expensive, I think the GR1- would have taken the iem world by storm. But the price is worth it if you have the money! The SE535 actually sound cheap compared to these, especially with classical music.

In ways, it's like an Etymotic ER4P for the 21st century. Reference + Musical at the same time?! I didn't think its possible. I don't know if Grado built this iem from scratch, but it sounds as if they did! They totally re-imagined what an iem should sound like. Instead of trying to one up the competition, they just made the most musical, controlled and comfortable iem out there. These are immaculately tuned.

It is also BY FAR the most comortable iem I've worn. These silicone tips are like a hybrid of a sony hybrid/klipsch gel. People always say about iems you actually forget they're in. Well, here is one of them. All you hear is music! (For those who are wondering, they could be worn either over ear or down. They also do a great job isolation outside sound.)

Expensive, but worth every penny, if you have the pennies to spend!

If I could make a few changes, it would be to include a case, to have user replaceable cables and to have them a different color than the pastel/metallic green!

I really like how Grado kept the small design like they used on the GR8. Very lightweight and compact so they can really be used for anything! I've used the GR8 a few times and was impressed, but I heard Grado was working on a new model so I held out and kept using my Skull Candys... well worth the wait. I read they used an improved armature driver and its got a much lower impedance. Overall great balance!!!! Incredibly smooth!!! Love It
