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

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 PortaPro 25th Anniversary Headphones


This series of headphones by Koss, known as the PortaPro is true retro at its grungy best. Reminding one of the late 80's moving into the 90's, these on ear stereophones come with punk rock written all over it — you can imagine contorted teenage faces...

At Rs 4,500, there is not much to complain about these cool headphones except that they're slightly pricey. They have a clean, wide soundstage, with especially sweet treble. Bass is powerful enough to satisfy my Low Frequency urge. The Portapro is a...

Koss PortaPro


The portable segment of headphones is a very interesting one as we get to see different innovative form factors, features and also some of the loudest and bass heavy sound outputs, naturally, to block out external sounds. The product we have is by...

At Rs.4,000 I would say the price is almost reasonable, as the sound quality is extremely good. There is ample volume, ample bass and enough clarity, plus external noises are hardly an issue. Now the flimsy headband can catch your hair, and as I said,...

Koss PortaPro (with Case)


With so many funky headphone designs flooding the market right now, it's getting harder and harder to choose which one to buy. Instead of showing you the latest snazzy set of cans, we're taking you back in time to showcase the Koss PortaPros. These...

The Koss PortaPro Headphones combine a functional design with excellent 3D sound and a low price tag.

Hair gets caught in the collapsible band; some people will dislike the '80s aesthetic.

Koss hit a home run with the PortaPros. Love or hate the design, there's no denying the sound quality here: they're the ideal companion for mobile audiophiles and home theater enthusiasts.

Great audio for the price.

Evil Dead 2: 25th Anniversary Edition


Just as with the first film, it's not long before the evil of the woods takes and possesses Linda, turning her into a horrifying, yet somewhat hilarious deadite. Ash then has to survive the night, which this time he succeeds (well, at least most of him...

One of the absolute best Horror/Comedies of all time ; Bruce Campbell as Ash. Hail to the King, Baby ; Sam Raim's creative and out of this world way of shooting a film is just mind blowing ; This is the best the film has ever looked and sounded ; An...

This movie deserved a digibook release! A digiNecromicon at that

Although some of the other features are from previous releases, they contribute nicely and help to round out a more complete package.

Koss PortaPro 25th Anniversary Edition Headphones Review


In a perfect world, things come full-circle. From the redesigned, retro-styled Mustang and Camaro to vinyl albums, products can go out of style only to come roaring back. Such is the case with the Koss Porta Pro headphones. Well, sorta the case,...

Amazing sound for the price ; Retro Style

Too expensive compared to the regular Porta Pros ; Retro Style

B.o.B. - May 25th Mixtape


Who is Bobby Ray Simmons? I'm sorry, I mean who is B.o.B.? No, wait, I think it's; who is Bobby Ray? Like his music, B.o.B. has the potential to be many things: a chronically high Atlanta rapper, a singer who likes to perform onstage with an acoustic...

Koss Porta Pro Headphones


Consumer testers noted that Koss' Porta Pro pair was just mediocre in terms of comfort, and sound quality also earned middling scores in GHRI tests. But the headphones were the most portable of the bunch we tested, thanks to their fold-up design. Plus...

Product Specifications

First introduced in 1984, this high quality portable stereophone set performance and comfort standards for personal listening worldwide. Over the years, much to the delight of devout PortaPro enthusiasts, the company has preserved the original design and performance that made the PortaPro a portable music icon. Today the PortaPro remains the headphone of choice for the discriminating listener. Designed for those with refined musical acuity, the PortaPro continues to be the most requested headphone. The PortaPro features dynamic elements that deliver exceptionally rich, deep bass and a remarkably wide frequency response from 15-25, 000 Hz to capture every nuance in your favorite movie or musical performance. Constructed from Mylar, the elements are extremely rigid, minimizing mechanical distortion and ensuring exceedingly accurate sound reproduction. Neodymium iron boron rare earth magnet structures enable the PortaPro to deliver greater volume so you can hear every note, even when competing against the sounds of a commuter train with a low-voltage MP3 or disc player. Oxygen free copper voice coils improve signal transmission and conduction for cleaner, clearer sound. Foam earcushions provide an open, hear-through sound that lets you keep in touch with your surroundings perfect to wear while running, at work, or while traveling. Whether you're listening at home or on the go, the Porta Pro will bring the excitement of a live performance to any recording.
