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 Hi-Fi
Home/Office
Studio
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
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.
No
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.
No
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.

Corded
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.
No
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.

Refers to whether the headphones use a 3.5mm or 1/4" headphone jack connection.
3.5mm
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.

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.
45 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".
115 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 - 20000 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.
Yes
Built-in Amplifier
This refers to whether the headphones have an amplifier built-in.
No

Great sounding IEM

July 27, 2015

Very pleased with my purchase of the UM Pro 50. Very efficient, good isolation, incredibly comfortable. The Pro 50 really packs a punch with the mids and lows yet you don't lose any detail with the highs. The pro 50 has become one of my favorites.

Musical IEMs with superior clarity and a touch of Extra Bass (Lush and Warm, Not Boomy)!!

December 20, 2015

First of all, Great Customer Service by Sonix Electronix, speedy shipping and great prices. Thanks.

Review of this IEM: I have previously owned Ultimate Ears SuperFi 5 Pro, UE Triple Fi 10, Westone W30 and W50. Also had Shure SE846 for a brief period before I sold it on eBay. By far, this UM Pro 50 is the BEST sounding earphone I ever owned. Obviously, sound quality is subjective to people because everyone has different sensitivities and tastes. But, Westone UM Pro 50 excels in clarity of sound. I could hear every nuance in a song, all instruments come alive. It sounds more open and I have heard sounds in the same songs that I have never heard before.

Shure SE846 is probably at the top end of Universal IEMs with a price tag close to $1000. It has a laser-etched low-pass filter that Shure claims to produce a subwoofer bass. That's probably their best marketing point to justify that whopping $1000 price tag. But when I owned it briefly, although they are still the king of bass in a universal ear monitor, the instrument separation and clarity of sound wasn't as good as UM Pro 50. Also, SE846 doesn't sit well on my ears given the fact that I am wearing a $1000 earphone :-). They are a bit bigger and bulbous because of the tech inside. The build quality was the BEST I have ever seen, especially with the clear case you can see the engineering marvel inside. But, I sold it on eBay with a loss. This is not to trash SE846, but the price:performance/value ratio is not as good for SE846, unless you have a lotta cash lying around and want to spend on a cool gadget.

UM Pro 50 is tuned to have a slightly more bass. This is not a muddy, boomy, dull bass. The bass is lush, warm and it rolls off elegantly. Just a touch more bass in all songs. Since I like that little bit more bass, combined with the instrument separation, soundstage, clarity and a musical sound, this fits my bill so well.

As far the other Westones I owned (W30, W50), they are good, but they don't come close to UM Pro 50's sound quality. Westone takes pride in their UM Pro line because they started in IEM business with these models and it's close to their heart I think. UM Pro 50 is designed and built in the USA!!!. Yes, you read that right - these IEMs are handcrafted right here in America.

Westone IEMs are one of the, if not the, best IEMs to wear comfortably for a long time. Since Westone is in the business of hearing equipment for so long, I think they have the expertise to make their IEMs fit so comfortably in the ears. I can wear these IEMs for hours without even noticing that its there (except for the great sound, of course :-)). The silicone eartips that Westone supplies with all of their IEMs are super comfortable. I usually use those silicone tips over the foam tips. Since this model has a slightly more bass, I think its better not to use the foam tips which will enhance the bass even more because of their tight, snug fit in the ears. But, again, of course we all have different ears and what fits me may not fit others. Try different tips and choose the one that fits and sounds the best for you.

If I compare Westone W50 and UM Pro 50, since UM Pro line caters to studio monitoring, the sound is much more clearer to me as you can hear all the instruments in a wide open stage. Westone 50 is a good IEM, but its bass is a bit overwhelming and its lack of clarity in sound makes it a bit more warm. On the other hand, UM Pro 50 also has that extra bass, but it sounds much much better than W50 as it makes it up in sound clarity.

Overall, I am very happy with my purchase of UM Pro 50. I hear all my songs from an iPhone 6. I don't have any Astell Kern, iBasso or Fiio Hi Res players. But, this IEM sounds so good with any type of song (mp3) right out of a smartphone. Its obviously much better if the mp3 bit rate is higher. I can only imagine how this IEM will sound with FLACs and other Lossless formats. Compared to W50, the impedance of this IEM is a bit higher. But, I still cannot crank up the volume more than half on my iPhone. Half way on the volume control is already loud enough for me. I will go deaf before I can crank it up all the way :-). So, basically this IEM does not need any external amp and all smartphones or iPods can easily drive them.

Obviously, over $600 for an earphone is still not cheap. But, when you commit to buy a high-end earphone, you are probably expected to pay around $500. If you can spend a little bit more, UM Pro 50 is worth it. Great sound stage, superior clarity, musical and with that slightly extra bass, it makes any song sound wonderful. Comfort is top notch. If there are any CONs, I would say that the build quality could be better. Make no mistake, these IEMs are sturdy and they are crafted well. But, say if I compare Shure SE846, the build quality could be better. And, you also don't get an iPhone/Android cable that has mic and volume control. You do get them in the W Series, but not UM Pro series - its understandable because Westone markets these earphones as studio/stage monitors. But, the braided cable that comes with UM Pro is great quality. It doesn't tangle up that much, easy to store and use. I also hear that the quality of sound on braided cable, which are made for professional use, are better than the iPhone/Android cable. If you ever need the convenience of a cable with mic/volume control, it will cost you about $50 to buy a Westone branded MFI cable. But, in my opinion, (since i have used the smartphone cable in W50 and W30), the braided cable is better in terms of quality (if you can forego the convenience of skipping a song or adjusting volume or using the cable to take a call). You can still take a call using the braided cable, just make sure you hold the phone's mic close to your face so that you are audible to the caller.

These are going to be used as in-ear-monitors at my church. I'm the worship pastor, and need quality ear phones. I've been using Westones for 7 years now, and am very happy with their performance and quality. This will be an upgrade from the UM-3, which I've been using for 3+ years now. Looking forward to better sound with the 5 driver system.
John H on Jan 5, 2016

Ivy B on Oct 23, 2015
I use in ear monitors for recording my vocals. The more accurate the monitors, the better my pitch.
Shaun O on Nov 27, 2015
This is one of the best all-BA universal earphones I've ever heard. The bass is phenomenal, but it doesn't infringe on the rest of the sound spectrum. Sonic Electronic was quite helpful in guiding me to make the right choice. Now I can't wait to hear what its big brother, the W60, sound like.
