I considered what I wanted these headphones for and it was to study in places like starbucks or barnes and nobles. So naturally, I decided on sound isolating headphones. This left me with either closed full-size over the ear headphones or earbuds. If you haven't seen them, full-size headphones are huge! They pretty much cover the entire sides of your head, we're talking Princess Leah hair buns (star wars). Besides that, the higher quality headphones require an additional portable amplifier to sound good because most portable devices aren't powerful enough to drive them.
Now I focused on earbuds. After reading review upon review about Shure and Etymotic, I would always come across reference to Koss "The Plug" and Sony's isolating earbuds (forgot the model) from an audio forum. Out of the box, the Sony is supposed to be better than the Koss model. However, what I found was that for a fraction of the price of Shure and Etymotic brands (I think the top model is $500) and a bit of elbow grease, the less expensive Koss earbuds could sound better than the Sony's and nearly as good as the Shure and Etymotic. Doing a search resulted in many websites referring to methods of "modifying" the Koss earbuds.
I was convinced and went looking back in April. However, when i got to the store, I couldn't find any "The Plug". All I found was "Spark Plug". I was confused but I bought them anyway. I searched amazon and realized that they must be the 3rd iteration of Koss's earbuds because I only came up with one result, and it said it was added to amazon only 2 days before I bought it locally.Read more ›
I'm not an extreme audiophile, but I do appreciate good clean sound. I like medium-strong bass, but it has to be clean and not muddy and not overpower the rest of the frequencies. The bass in these Koss plugs might be just a bit too much, but certainly not enough that I'm going to bother trying to modify them with straws and duct tape. You can adjust the position of the phones in your ear to reduce the bass, too. Overall, the sound is quite good, but not as clear and bright as I would expect from expensive phones.
Someone said they look funny in your ears. I suppose that's true, but I don't care all that much.
In summary, they sound very good (but not excellent), they are comfortable and stay in my ears, and they are incredibly cheap! Highly recommended. (P.S. please be careful with volume levels to avoid long-term ear damage. Really. Can you imagine not being able to enjoy music when you're 40 years old? How horrible! Turn down the volume and your ears will adjust to the lower level.)
Still, these are cheap earplugs, so don't expect top sound quality. I find that the foam tips on these earplugs fit my ears better than a pair of more expensive Sony earplugs that take those replaceable foam covers. Granted, the sound quality is less than those higher-priced earplugs, but I can wear these Koss earplugs for far longer in comfort.
My only complaint is that they are a bit bass heavy. EQ is kind of a must. Also, I like to trim a bit off the end of the "plug" with some scissors. I have listened to all kinds of music through these things, nothing is muddy, not deep house, not trance, not trip-hop, not bluegrass, not anything. Clean and crisp. Amazing.
I threw away the foam pads that came with them almost immediately and fitted them with a pair of normal squishy earplugs. These are the kind of earplugs that are made of memory foam that you roll between your fingers and let them slowly expand in your ears. To prepare the earplugs you have to shorten them a bit with some scissors then "drill" or actually melt a hole through them with a hot piece of coat hanger. Then you fit them over the plastic tubes that come out of the Koss Plugs. To me the prepared ear plugs are much more comfortable and seal much better than the foam pieces that come with the Koss Plugs.
I have a Sony active noise canceling headset, which is good for environments with low levels of back ground noise, but are not adequate for very noisy environments, such as when you are using a leaf blower or working around heavy equipment. In this type of situation I use the Koss Plugs and a pair of muff style hearing protectors. When using them like this however you must be very careful because the sound isolation is so great that even persons shouting will have a very difficult time getting your attention.
The Koss Plugs take much less energy to run compared to other headsets. You must use a much lower volume setting. The sound quality is excellent. They are cheap and durable; unlike ear buds they stay in your ears when you are working or playing.

They are very good headphones, I love the quality of the low frequencies. The foam is very good to keep the outside sound outside. The length of the cord is OK. Read morePublished 12 months ago by Henrique Gomes
