The HEM Series also comes in different driver configurations to suit everyones needs and budget. There's the HEM8 w/ eight drivers total, HEM6 w/ six drivers total, HEM4 w/ four drivers total, and the HEM2 w/ two drivers total. The higher number of drivers, the more accurate and full sounding the headphones will be, and all versions are Hi-Res certified.

Headphone Design

Headphone Type

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.

In-Ear
Headband 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.

Earbuds
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.
Home/Portable
Headphone Application

This is the application that the headphones are designed for. Each application has unique features that make it perfect for particular uses.

DJ: These headphones are durable, loud, and will often allow for one ear listening.

Gaming Delivers explosive sound and allows you to communicate with others.

Home Hi-Fi: These audiophile headphones are engineered to produce high fidelity and accurate audio.

Home/Office: These headphones are designed to produce rich, brilliant sounds that the artists would appreciate.

Sports: Designed for active use. These headphones are made to stay in (or on) the ear during workouts.

Kids: Feature noise limiting technology so that your little ones don't damage their ears listening to music too loud.

On-the-Go: On-the-go headphones are lightweight and often fold up for easy storage and portability.

Student: Compact and rugged enough to survive life in a backpack; inexpensive enough to not hurt the wallet of a student.

Studio: Reproduce music perfectly without any coloration. Look here for reference quality studio monitoring headphones.

Traveler/Airplane: These headphones are compact, lightweight, and have a portable design.

Home/Office
On-the-Go
Traveler/Airplane
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.

Closed

General Features

Noise-Canceling

Audio Features

Driver Type

The physical design of the driver in the headphones.

Balanced Armature:
A balanced armature driver uses a coil wrapped around an armature which is held in between two magnets until it is stimulated by an electrical current. When stimulated, this armature is magnetized which causes it to rotate one way or the other around a pivot point which moves the diaphragm to create sound. Balanced armature driver headphones are generally earbuds and can have multiple drivers in each earbud.

Dynamic:
Dynamic drivers are the most common driver type. They feature a permanent magnet, usually neodymium, a voice coil and a conical diaphragm to drive your music. A dynamic headphone driver looks pretty much identical to any typical home theater speaker.

Electrostatic:
Electrostatic drivers are made up of an extremely thin membrane, usually a coated PET film, stretched between two metal plates. An electrical signal is applied to the metal plates to create an electrical field which, depending on its polarity, draws the speaker diaphragm toward one of the plates which forces air through the perforations in the diaphragm which generates the sound wave.

Planar Magnetic:
A planar magnetic driver is made up of a large membrane suspended between two sets of oppositely aligned magnets. An electric charge is applied to the membrane to induce movement and produce sound waves.

Balanced Armature
Impedance
The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
26 ohms
Sensitivity
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".
110 dB
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 - 40,000 Hz
Audiophile
Audiophile headphones represent some of the finest headphones available. Audiophile headphones produce genuinely outstanding sound quality as well as extraordinary build quality, components and comfort. They are truly the finest headphones available.
No
Built-in Amplifier
This refers to whether the headphones have an amplifier built-in.
No
Amplifier Recommended
This refers to whether a separate headphone amplifier is recommended for use with a specific pair of headphones. It is highly recommended that any headphone with an impedance greater than 100 ohms be amplified.
No
Pass Throughs
Refers to whether a pair of headphones has an output to connect to another pair of headphones.
No

Nuforce HEM2

July 28, 2016

i use these primarily with my phone and rarely with an amp. that being said, they sound great, incredibly clear, they dont give much bass compared to my w50s. they're probably the most comfortable pair of in-ears ive ever worn, the cable that wraps around your ears doesn't irritate my ears at all, ive had that problem with other headphones with similar design (w50s..).

the case these come with seems pretty much indestructible, so that's nice. i also like that it comes with a cable with a mic in it, so many higher end headphones don't have a mic, that combined with the case make these my favorite headphones for travelling (not exactly what they're intended for, i know). durability wise, they seem like they'll last just fine, especially if you keep them in the case. the braided cable might have some issues as the split seems kind of flimsy.

Nicely Done

June 24, 2016

The HEM2s pair nicely with the uDAC5. The HEM2s come with two cables and an wide range of different ear tips. I used them with the isolation tips. The isolation tips do a very good job of blocking out external sound. Now it doesn’t block all of the sounds but enough of it. I did find the foam tips to be a little uncomfortable which why the silicon tips are more usable with my ears.

I found the bass to be a tad impactful and it does not merge into the other frequencies. In dub-step and DnB songs I found the bass to be tight and not muddy at all.

When I listen to songs with drums I can hear the snare snaps and high hats so clearly. The higher frequencies are the right amount producing great clarity and detail.

Sound stage is small. Vocals are a tad out of my head and it was hard for me to place the location of the voices in some songs. Although in some songs it sounded like they were in front of me.

Separation between instrument and voices is very good. I can easily tell everything apart from each other.

Sound good and light weight

May 27, 2016

I got these for the portability of in-ears, but picked these specifically because they seemed a lot nicer than most of the others I was looking at. I'm very surprised how good these sound, they seem very clear. Not much on the low end of the frequency spectrum but i'm sure if I messed with an equalizer I could open up the bottom end a little more. Over all I enjoyed these.

pretty cool lil buds

May 27, 2016

i've been using these for a few days now, and overall they are really nice sounding. very crisp sound, you can really hear every different instrument in the mix, and they sound very detailed. the only downside for me personally is they are lacking bass. Perfect for many types of music, but i'm tryna bump some hip-hop and the bass just doesn't do it for me. Don't get me wrong still a great pair of headphones, and i really like the design, they are very comfortable, probably good for the gym (but i don't workout lol) just not enough bass!

I really like the look of these and they sound great. I'm wasn't sure what 199 headphones should sound like but they are definitely better than the skull candy and other headphones I've used. I'm a happy camper for now.

For School

April 26, 2016

Hey everybody. I bought the HEM2 in a bundle with the Nuforce amp that Sonic had and I'm glad I did. I use these mainly when I'm on the move at school but when I'm in the library or at home i'll use the amp too. These sound really really good and my brother liked them so much he says he'll probably get one soon. These are way better than my beats earbuds and I like the color. Only downside is I hate taking them off in class because I'd rather listen to music than the lecture. Is that bad?
