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.

Over the Head
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.

For those that need the best in music quality. These audiophile headphones are engineered to produce high fidelity and accurate audio replication.

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!

This lifestyle speaks for itself! If you love video games and want a pair of headphones that will deliver explosive sound and allow you to communicate with others, this is where you need to shop!

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).
6 - 40000 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".
106 dB
Driver Size
This refers to the diameter of the driver (speaker) on each side of the headphone.
50 mm
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.

AMAZING sound, definitely delivers!

July 16, 2014

I recommend these headphones to anyone that is looking for a serious high-quality sound experience.
I have put these through rock music, rap/hip-hop music, classical music, and regional Mexican music as well... It handles and plays it all how it should sound.

When it comes to the sound-quality of headphones one should take in consideration that the "quality of your songs" contribute to the experience as well, but aside from that these headphones bring out anything you throw at them. They're great! and here is why:

I mostly listen to Electronic Dance Music and the SE-MX9 headphones give you every single sound in such good clarity. The bass pounds nicely, it's nothing like the flappy, unnecessary bass that some headphones deliver. In other words, the bass is delivered the way it is supposed to be... high, low, hard, and precise.

As far as mid-range and highs these headphones keep up with it all, it is truly clear and loud!! One can hear every sound distinctively, not mushed up and nasty. Every beat, every rhythm, at any speed, any time... with the punchy or broad bass encrypted along with it all!
One can switch from a nice (studying scenario) classical music experience to a loud (personal enjoyment) experience with a switch of a song and a few clicks of the volume.

Comfort-ability is key in sound/music experience too..
The headphones are comfortable over your head and around your ears, the cushion feels nice (they say I have a bigger-than-average-head-__-), BUT the fit is just tight enough to keep the headphones on your head, would not recommend super-head-banging with em tho. I personally would have preferred them to be just a LITTLE more tight.

As with all over-head headphones, they tend to be slightly-heavier than average on-ear, and may get a little hot/sweaty after 2-hours of listening.. but once you hear and use these headphones, that will be the least of your worries.

The SE-MX9's ability to block all exterior noise is great for not having any sound-cancelling technology, nice tight seal.

As far as sound-leakage, the nice tight seal helps with that.
I blare music from time to time, and I've had others play them at all levels while wearing them next to me to confirm this... they BARELY leak at 3/4 and slightly higher sound volume!
If you turn up the volume all the way, like painfully all the way, well of course they're gonna leak, but not ridiculously. The leaking is small compared to most over-the-head headphones I have tried out. (I've tried a lot of headphones, sound-leaking is my main priority as well.)

These headphones are big, but if you are like me and do not mind, you will notice that they have a unique nice sleek look to them when you wear them on your head. They have the "nice-big" look to them, not the "funny-big" in other words.

Wearing them around your neck feels comfortable too, the swivel feature helps with that, the headphones do not choke your neck instead rest nicely over your collar bones. The durability is good because of the simple design, if you use them for what they are meant to be used for that is. They have a slight plastic feeling when you hold them in your hands, but it is more of a sturdy feeling to them, they are nicely built.

The pictures say it all as far as style, the appreciation of style rests on your hands. I personally love it, the only thing is that I wish they made a dark black design.

The in-line microphone works and sounds really good, I do not like that the cable is half red/half black but like I said, those are the least of my worries. The longer DJ cable seems flimsy but never worry about the cable accidentally being pulled out. (headphone-lock feature)

Over all these headphones are great, Pioneer delivered with this one. Do not worry about the price, you actually get what you pay for with the Pioneer SE-MX9.
These headphones deliver from the every day listener/student to the DJ constantly handling them while laying sets. You will experience sound in all sorts of great and maybe even new ways in respect to your personal choice of music.
