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.

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.

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.
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 Hi-Fi
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.
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.
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.

Bluetooth means that the audio signal is transmitted from your device to the headphones via a Bluetooth connection.

Corded or Bluetooth means that the headphones can be used as corded headphones or as Bluetooth headphones. They have an input in one or both earcups for use as a corded headphone while they also have a built-in battery for use as Bluetooth wireless headphones.

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

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.
Connector Type
The type of connection the headphones use to connect to receive the audio signal from a music source. Traditional headphones use an analog 3.5mm headphone jack. Newer technology has allowed digital signals to be sent directly to the headphone using an Apple Lightning or USB-C cable.
Jack Size
Refers to whether the headphones use a 3.5mm or 1/4" headphone jack connection.
Jack Angle

The Jack Angle refers to the angle of the input jack on the headphone cable.

Straight Jack: Straight plug with no angle.

Angled Jack: Angled plug, usually a 90 degree angle.

Swivel Jack: A swivel jack is able to swivel between a straight plug and an angled plug.

Angled Jack
Detachable Cable
Refers to whether the cable can detach from the headphones. If a pair of headphones has a detachable cable, the cable can be replaced with a longer cable, one with (or without) a microphone or if you accidentally damage the cable.
Color Shades
Primary color shades of the headphones.
Refers to materials used to build the headphones. Most headphones are built from some combination of plastic and metal to give you a durable pair of headphones.
Ear Cushion/Earbud Material
Refers to the material that the ear cushions/earbuds are made from. Ear cushions and earbuds are available in a variety of materials, ranging from basic rubber eartips to plush leather ear cushions intended for maximum comfort.
Protective Case
Refers to whether a pair of headphones come with a protective case.
Softshell Case
Water Resistant
This refers to the level of water resistance of the fitness tracker. Some fitness trackers are water resistant and can be used while swimming, while others are only splash proof or should not be used near the water.
Ear Hooks
These headphones feature hooks that wrap around your ears for a secure fit.

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 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 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.

The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
16 ohms
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).
10 - 20000 Hz
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.
Built-in Amplifier
This refers to whether the headphones have an amplifier built-in.

Awesome in-ear headphones

May 28, 2014

The Sennheiser IE 80 headphones are awesome. I gave it 5 stars in every category except features, because it would've been nice to have a built-in microphone for calls and/or volume and playback controls. Those are not deal breakers for me, and honestly I don't really need them, but a lot of headphones include those features currently.

Bottom line is if you are a music lover of all types, these are your headphones. They sound great with everything that I've thrown at them. The bass will make you smile.

Sennheiser's Midrange Earphones: Give them a chance!

November 11, 2015

My experience with the IE80 East in-ear monitors has been pleasant, though slightly dulled compared to other options I currently possess for less funding.

Pros of this product are plentiful, beginning with a well-structured, durable packaging for security and reassurance of an unharmed purchase. These earphones feature an option to modify bass response using a screw mechanism(tool included) located on each earphone, which was useful for 'fun', club-style listening options. The stainless-steel earphone accents provide a formal appearance, with a slight amount of show for passerby, as well as durability for accidental mishaps because we are human. The included ear tips were an incredibly diverse assortment and I believe one to fit nearly everyones' ear canals as well. I also appreciate the detachable/replaceable two-pin cable that attaches to both earphones and terminates in a 3.5mm(1/8") plug. The cable was also quite lengthy, near three-four feet. The soundstage is very well-spaced, and the isolation(especially when using the foam tips, which are my favorite) is phenomenal, surpassing standard hearing safety earplugs dB reduction.(in my personal opinion) The low-end of these in-ear monitors is also astonishingly deep. Finally, the reassurance of a two-year warranty is the icing-on-the-cake for this product; Sennheiser will take great care of its customers and their products into the future.

Cons regarding this product were few, but clearly evident. The storage container for the earphones does not easily accommodate them, let alone the numerous ear tips.(four pronged holders+currently used ear tips) A shame, as the storage container is well-built and surrounded in stainless-steel for additional reassurance. The frequency response of these earphones also slightly suffers from flat bass,(at times) tinny treble, rolled-off highs, and a "forward" midrange with deepened vocals.(both sexes) Sadly, I own a fifty US Dollar pair of earphones that were more balanced and responsive than these in-ear monitors, though they were completely plastic, provided a nylon/vinyl case with multiple ear wings,(to retain them in your ear, which I feel they did not need) a flat cable, in-line microphone to 3.5mm plug, irreplaceable cable, solid packaging, six choices of ear tips, and a one-year, Five-Star warranty.

Overall, this product was rather overpriced, in my personal opinion, though its portability, durability, bass-manipulation feature, and warranty are certainly valuable assets for this investment. I would still recommend these earphones for the individual who enjoys music with a favored low-frequency response and mild vocals, but certainly not to a high-frequency listener who also appreciates bolder and more pristine vocals.

Full disclosure: I was the second place prize recipient in Sonic Electronix/Sennheiser's Head-Fi Sweepstakes and was awarded the IE80s free-of-charge. I was also given the optional task of writing an honest, unbiased review of their caliber on Sonic Electronix's Website, which I have completed above. Thank you, Sonic Electronix/Sennheiser/Head-Fi, for this grand product. I shall treat it will the highest care for years to come.(guaranteed)

What is the different between IE80 East and IE80 West?
A shopper on Jul 4, 2015
Best Answer: The product is the same - the earphones are identical. The difference is in the packaging, with different languages relating to the markets where the product is sold (broadly, East = Asia, West = Europe/NA)
