I'm just going to give a brief opinion here because the other reviews for this product as so technically accomplished. These Koss plug earphones have become one of my favourite gadgets. I bought mine for around £8 on eBay. I had always been looking for performance earbud headphones as I like high sound quality but I don't really have the funds to spend on the high -end gearb. At around the time I bought these I was eginning to notice that the high-end design for earbud headphones all seemed to be based on sound isolating earplugs (Shure, Etymotic etc). I was pleased to see these come on sale as they seemed to utilize the same design but unlike any ...  Read the complete review

These Koss earphones are amazing, they isolate outside noise simply by using earplugs which insert into the ear canal and seal out any unwanted noise, as well as preventing any sound from leaking out. This means that you can listen to music at lower volumes and still be able to here it clearly. They block out the majority of noise around you, so you won’t hear a baby crying on the train but you won’t hear the announcer either! Before I got these headphones the only way I could clearly hear my music in loud environments such as busses was to turn the volume right up, which is obviously not good for the ears or the distortion it causes. Now though I ...  Read the complete review

Ive been using these headphones for a few moths now in combination with my zune MP3 player. They offer great value for money, I purchased mine from Amazon for just £9.95. Watch out when purchasing from Amazon Marketplace or ebay as many fake headphones are sold there and offer poor quality.

The headphones also come with two different size foam attachments so that children can use the headphones. The headphones offer good fidelity and allows you to ...  Read the complete review

I love these head phones, i found these on amazon.co.uk for the bargin price of about £4.95 i think (it was a while back) and the reviews where good. so i thought i'd give them ago at that price. Brilliant... The squishy in ear memory fome ear pieces where a bit long, so i cut them down with a blade and bingo, great fit. the sound really was amazing, for drum and bass and hip hop the lows were low and the highs sharpe! however the only problem i had was the first set i had broke easliy as putting them in and out of pockets and bags took there toll, so i got another set and same great sound but the same fate took these one's to, but to be fair i dont really look ...  Read the complete review

These earphones look a little bit disturbing at first and the thought of putting them into my ears was one that I didn't not relish in to begin with. But I took the plunge and did it. Unlike most in ear earphones instead of ear buds the Koos 'plugs' use a pair of sort of foamy, marshmallowy like well.. plugs! They do the job of plugging up your ears thats for sure. With them in most sounds are severely dulled and silenced leaving you to listen to your music almost uninterrupted by the outide world. My first impression was that the earphones gaves a very bassy sound, too bassy in my opinion, an unusual area in which earphones struggle usually being too tinny. ...  Read the complete review
