Product Description

The Koss Plug revolutionized the world of in-ear headphones. A first of its kind, these are stereo, noise isolating in-ear headphones that deliver the kind of accurate acoustical reproduction and isolation typically found in high-end, closed-style high fidelity headphones. A dynamic element positioned just outside the ear connects to a tubular port structure that inserts into a soft, expandable cushion. The soft, foam cushion expands for a custom comfort fit with every listening experience. It also improves isolation, plugging out ambient sounds, and enhances deep bass and treble clarity.

Amazon.com

Koss's miniature portable earphone, affectionately dubbed "The Plug," makes use of an ear-cushion material (similar to that used in sound-blocking earplugs) that slowly expands in your ear canal to provide a custom fit and maximum sonic isolation from external noises. A detachable, extrawide headband makes these Koss-termed "stereophones" easy to carry or store.

For accurate sound reproduction, these earbud-style headphones are made with oxygen-free copper voice coils and neodymium iron boron magnets. You can enjoy them with either a portable or home audio device, since both 0.125-inch and 0.25-inch adapter jacks are included.

"The Plug" weighs a mere quarter ounce and has a frequency response rated at an impressive 16 to 23,000 Hz (though its unlikely you'll hear bass output anywhere close to what you'd get from a similarly rated loudspeaker!).

Impedance is 16 ohms, with less than a 0.3 percent distortion and reasonably high sensitivity of 112 dB SPL/1 mW.

NOTE: the description I saw on the Amazon page does not reflect the product I have. Above it discusses a headband and an adapter which are not part of this product. Also, the rated frequency response is 10-20k, not 16-23k. I think this is (or was) an Amazon editorial error.
My interest for this product is as a solution to listening to music, lectures, and movies while travelling, and I travel a lot. I have a set of Panosonic noise-cancelling headphones which were good (about five times more expensive than these earbuds) though bulky, but the plastic broke so they won't stay on my head now.
These earbuds are an excellent alternative to noise-cancelling headphones for the frequent traveller. I find them more comfortable for extended listening than most conventional headphones. The ability to seal out noise from the external environment is very good, and makes it possible to understand what actors are saying when watching a movie on an airplane.
The overall performance - sound quality and noise blocking - is not as good as the Bose noise cancelling headphones, but the Bose are 20 times as expensive, much less convenient to carry, and subject to damage from the rough world of the road warrior. If The Plug had an optional noise-cancelling unit (say, combined with the eq), it would be a killer combination - are you listening, Koss?).
The sound is good. Bass-heavy, to be sure; I would like them better if they had a flatter response, but the product is marketed at the portable music crowd, and many of them are looking for dramatic bass rather than golden-ears sound.
Besides, mobile sound is always a compromise, it's just a question of whether the compromise they chose works for you.
Here are some problems I've heard and the solutions:
1. "They fall out of my ear.

Size: Old Bluetooth 3.0Color: Red S9 Verified Purchase
Received the headset and was eager to try it out. Looks sharp with the red and black styling. First fit was good for my small neck and ear buds sat comfortably in my ear. The red plastic covering the back of the neck was loose on one side. Tried to push it back but it did not stay. It wasn't a snap joi nt but it needed to be glued in place. No big deal. Will do that if I decide to keep it.

Unfortunately I will have to wait for some instructions before I can review the sound quality and pairing capabilities. I could not truth this unit on. There is one pin hole marked with on/off below it. Tried the usual paper clip method but can't feel any clicks and given the fragility of the product, I dare not pushed too hard. Waiting for others to comment on how to turn this unit on and off. If unable to do that, it is going back.

Update:
Vendor replied with options to return or replace it but I got it figured out and now testing the unit before final decision.

Do not stick anything into the pin hole. It is not a switch but the LED. What's mark as on/off is really the status led.

The instruction in the back of the packaging refers to a Bluetooth key, that's the play button or the center button. Hold that for about 5s to turn it on. This is also the talk and hang up button.

To pair, press the play button and hold it until it alternates between blue and red for paring, this can only be done from the off state.

To turn it off, Press the play button until you see it flash red. Let go of the play button.

To turn it on, press he play button until you see a blue light, let go of the button.

To answer or hang up, press the play button.

Size: Old Bluetooth 3.0Color: Red S9 Verified Purchase
This is the first Bluetooth headset I've owned. It's a no name brand from China so I didn't expect much. The instructions included are fairly useless, but I really had no trouble with the set up. I'm no audiophile so I can't speak to the quality of the sound because I use it when I'm walking for audiobooks, plus I've got a little bit of a tin ear. But it sounds clean and clear to me- no interference at all. When I got it, I was on my way for a walk, so I figured I'd try it out right away- no charging first. It lasted through the whole half hour walk. When I got home I charged it, and within a half hour it completed the charge. (I don't know how long the charge will last, if need be I'll update the review). As the title suggests, it's a great value- you'll pay this much for a regular set of wired headphones (Which I hate like Wile E. Coyote hates the Road Runner). So I'm very happy with the purchase.

BATTERY CHARGE UPDATE- I use these headphones for about 30 minutes every day and the charge lasted about 2 weeks before it needed a recharge. When the battery is low, you'll begin hearing 4 quick beeps every 15 seconds and then after a few minutes, it will shut off. Also, I forgot to mention that I'm a 'big and tall' guy so the back of my neck looks like a package of hot dogs, and I would describe the fit of the headset as snug. It's not too tight but almost, so if you're not a Heavy Chevy like me, they will probably fit perfectly comfortably.

I heave read many of the review on this site, and I probablly would have not used my Koss earbuds to the full extend if I have not read many of the reviews. First issue is that people cannot get the earbuds to stay in their ear. I found my earbuds not needing any modification when it comes to foam, but rather they way the earbud is placed in. The first problem that I had is stuffing it in my ear, they would fall out, and the foam would look all pushed back on the stick (refering to the rubber sticking out from the headphone). YOu must firmly squeze the foam from all sides and quickly insert it into the ear. You will know if the ear bud is firmly in by shaking your head, and nothing is falling out. Do the same for thea other ear. Now you will hear the amazing quality of the sound that these pupies can give. The base is amazing, these earbuds I find better quality then my Sony Studio Monitoring headset (one great advantage of earbuds, the volume on my MD player doesn't have to be set to the max to hear any music). The sound quality is amazing, the isolation from outside is great, especially on a loud bus, unlike other earbuds. ONLY IF THE EARBUDS SET PROPERLY INTO THE EAR YOU WILL HEAR THE FULL QUALITY OF THE SOUND... I heard no distortion...I hope my review helped you on earbuds.
