Koss KEB40 Earphones Review


Koss, an American company famous for their Porta Pro headphones have officially made their entire line-up available in India. We've in fact reviewed the KSC75 clip-on earphones, which offered a decent listening experience for the price. Today we have...

With a hefty price tag of Rs. 2,400, these are too expensive for the kind of performance they deliver. Earphones such as the SoundMAgic PL11s offer much better audio performance and are cheap at just Rs.550. What Koss have managed to create are some...

Koss KEB40 Insider Headphones Review

Koss KEB40


The quality and the power that Koss provides through their earbuds are enough to impressive even the toughest sound critics. Despite the atypical, slightly bulky shape, they seal the ear very well and help to keep our music in and unwanted sound out....

These earbuds have fantastic bass response, sometimes stretching below the range of human hearing

The Koss KEB40 earbuds are only available in black

For their impressive bass response, lifetime warranty and slick design, the KEB40 earbuds place themselves near the top of our comparison.

I Keep Buying Them But Don't Know why


I have bought more of these over the past five years than I can count, and I don't know why. They're flimsy, they don't last, and I can always count on one earbud always failing within a month. I guess I buy them because they're Koss. My advice is:...


flimsy, short life

As inexpensive as these things are and as good as they have performed for me I will be buying more..................

I bought these to replace my Senheiser buds that served me well for a few years. I needed more bass and these things delivered-maybe a little too bass heavy. I went to the media player's equalizer settings and tuned them just the way I wanted them to...

All the wires on the plug and speakers are straight in.I would have liked them at a right angle instead but no biggie. You have to be careful about removing the earbuds and phone jack not to pull on the wires--same as any other earbuds. Time will tell...

Sound good but only when properly in your ear


Not the worst headphones I have ever owned either and, to be honest, considering they retail for less than $30 and I got them for less than some I have seen next to gum in a checkout line I think they are a fairly good bargain.

Inexpensive, durable and comes with 3 sizes of earpads so you get a better than average chance of having them fit well. I purchased these as a low cost headphone to use at the gym because I keep tearing up every set I take there and figured I better...

Must be in your ear "just perfect" to get the optimal sound. If they are in too far, not far enough or they are loose and shake into a non-optimal position the sound degrades from above average to poor. That's all more of a factor of the type of...

Buy these!


I spent 24 hours breaking these in with heavy bass songs at 50% volume to really flex the speakers inside and after i did that they sounded incredible!! I do this with all my new headphones.

Cant say enough good things about these, they really insanely good ; The bass is perfect its not insane its well balanced ; They feel comfortable for me

The highs sound a little "tingy

Koss black keb40


Its one of those earbuds you don't feel bad if it breaks when you throw it away.

Its $4 shipped. Decent bass

No mids, sticks out awkward and the cable is cheap

Great at the price I paid


Excellent sound for budget earphones (I paid <6 bucks)

Unusual design makes them stick out of the ear more than usual. This also causes the wires to route a bit strangely. Not exactly uncomfortable, but takes a bit of getting used to

Spend another 10.00$ get something different.

They work

Quiet, not loud enough by far. I have some old half broken Sennheiser ones that out preform these easily
