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.

Earbuds
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.

In-Ear
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

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-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
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.

Corded
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.

No
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.
Yes
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.
Yes
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 - 19,000 Hz
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
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.
Impedance
The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
18 ohms
Primary Color
This is the main color of the item.
Black
Secondary Color
A color that compliments the main color of the product.

High quality, minor issues

June 15, 2013

Very good quality earphones. Probably the most comfortable passive noise cancelling units you can buy. Bass is too exaggerated (I use with "bass reducer" setting on iPhone EQ). Only other complaint is the cable which is stiff and takes a set to the shape it is in the box and apparently stays that way for good.

Klipsch Reference S4i In-Ear Headphone

June 3, 2013

I bought these headphones because my other headphones wouldn't fit in my iPhone headphone jack with a case on it. It has been almost a year since I purchased these and they are still great. I like the built-in microphone for making calls, people can here you without having to move it close to your mouth. I like the sound quality from the speakers good highs and lows, just make sure you choose the right rubber adapter for ear. Overall I'm very happy with them and would definitely purchase them again.

A glowing reference!

November 19, 2012

I consider many options, read a lot of reviews, did a whole research, I was looking for something that could reach my standards. After more than six months of use and new options out there I would still buy these. To begin with, Sonic Electronix offers an unbeatable price and ships without issues. You get the value for your buck. I’m really amazed, the 18 ohms impedance matched with the noise isolation allows to listen even at the lowest volume set. It’s true that you experience each and every single instrument, honestly, like listening to your music for the first time.
Some facts: 1. you might have a hard time for them to fit your ears, but that’s solved with the right tips, 2. if not fitted properly you would miss bass, that if you actually notice, we’re talking about the bass you miss with most commercial headphones anyway, 3. they give you a fragile feeling… but no, they’re not that fragile, the new cables with built-in strain relief really do their job, I’ve been using them everyday to deal with public transportation, they don’t have a scratch, and no, the cord doesn't get tangled 4. the only issues you get are those for any other in-ear, but these are the only ones who would match, if not beat most speakers.
They sound so natural I usually find myself forgetting I’m wearing them, they’re really light but they can sound like a concert. You would never look back, they’re indeed a reference.
P.S. the case is just the right size as you can check on any picture, but it has a custom size foam inside which you can actually take away if it gives you any trouble…

COMFORTABLE EARBUDS !!!!! EXCELLENT SOUND !!!!!

November 12, 2012

Let me just say that these earbuds are the only pair that fit my very very small ear canal with the tips that come on out of the box. They come with a total of four from really small to larger. They will definitely fit all ears. Not like all the other'd out there that hurt your ears after 10 minutes these you will not know there there after hours of listen pleasure. Great sound reproduction from lows to highs to good bass. Very light so very comfortable. Good company to purchase from !! Great price and fast delivery. Buy these buds from this company an be happy listening to your music without ear pain !!!!! Thanks !!

Klipsch Reference S4i

November 1, 2012

I really like these earbuds, big improvement over what came with the iPhone. Those became uncomfortable to wear for more than 15 minutes, whereas I can wear the Klipsch for a long time. Having a bit of trouble with the size of the foam, the large is too large and the medium is too small. I just read on someone's review about Comply TX-100 foam tips, I think I'll buy them. Great sound and comfortable to wear.

best earbuds under 100$

October 18, 2012

I won't waste your time and just say, that even after almost 4 years since the release date "klipsch image s4" is still the best earbuds for under 100 (or maybe even 200$). Klipsch reference s4i is basically the same earbuds but with a few cosmetic enhancements, mic and also a remote optimized for apple devices. The only negative aspect of this product is the case, its too small and it takes too much time to cram in the earbuds. If you own an android based devise check the s4a model that is optimized for android. If you are looking for better ear tips you should check Comply TX-100 series foam Tips.

I Pod earphones

September 28, 2012

The ear phones that come with an I Pod are unbelievably uncomfortable. I started looking at something better but still as portable. Looked at the Klipsch S4i and ended up purchasing them. Very comfortable although I think they are a bit over priced. The wiring also twists and is hard to keep out of the way when exercising with them.

Excellent In-Ear Headphones!

June 12, 2012

I own lots of Klipsch audio products, and the Reference S4i In-ear headphones are excellent! They deliver crisp, clear detail. Well rounded highs, mids and lows that the reference series are known for. They look nice and the controls on the cable are very functional. The Reference S4i's are well worth the purchase!

Very good sound, and very comfortable. But they are not easy to put on, they don't fit as perfectly as other models. The design may not please all.

If they are not placed well, you hear ambient sound and no bass.

Klipsch Earphones S4i

June 18, 2012

Best sound quality of all the earphones I have owned including Bose. However, due to their larger size these earphones will not stay in your ear when riding a motorcycle. I don't wear a helmet and the wind blows the earphones right out. I am sure they would work well for anyone who wears a full face helmet and of course for anyone not riding a motorcycle.

Good sound, the cord doesn't get tangled, and they stay in ear really well. What's not to like? The only issue I had is that the built-in controls don't work for some older devices, but as long as you check compatibility first you should be fine.
