My over the ear type will always be served by my Koss PortaPro headphones (by and far, my favorite headphones ever). My dog recently chewed my old Sennheiser ear buds up, so I wanted something new. I thought I'd look into Koss given my preference for the PortaPros and I definitely don't regret it.
These ear buds are made out of aluminum, so they have a very substantial feel while not being too heavy. A smooth, shiny finish. Precision is one word that comes to mind when holding them.
The rubber seals are traditional Koss, the same ones as were on my $25 Koss earbuds. This is not to say they are bad, by any means. In fact, they are some of my favorite. They seal very well and can be worn for several hours at a time without feeling awkward. There are three sizes, I imagine nearly anyone can find appropriate comfort in one or the other.
The sound quality is very pleasing. Not quite at the level of the Koss PortaPros, but better than any I've heard from my extensive portfolio of Earbuds.
The first thing that I noticed is how clean the bass is. It's very strong, but not overbearing like some. It is not muddy, there is actual detail in all lower notes. The progression is smooth down to the lowest of lows (which these will go darn near as low as humanly perceptible.. maybe even beyond). It is all very nicely balanced. Smooth and Refined is how I'd sum up the low end.
The midrange is comfortable. It again is smooth with considerable detail. I personally feel there is one minor peak of sound somewhere between the 4-6khz range where these notes are stronger than competing frequencies when it gets loud, but nothing significant enough to deter anyone from buying (very minor tweaking with an EQ can achieve preferable sound). The treble is, as a common theme, detailed. I was expecting these to have a harsh high end, but they sound smooth and warm while maintaining considerable amounts of detail.
The channel separation is another one of the first things that I noticed. Very impressive. Very little stray signal noise.
On the negative side of the spectrum, I do not like the asymmetrical cord. I honestly don't see the point of any set having an asymmetrical cord. I have had occasions where my left ear bud is yanked out because the short cord. The rest of the cord is the perfect length though. Another gripe I have with the cord is how thin it is. I feel like I'm going to break it if I pull on it too hard (accidentally). Also I'd be worried about the longevity of where the cord plugs into the bud.. I would imagine that after a year or two of use, the insulation would wear out and the wire would fray.
Thankfully Koss covers these earbuds under their "No Questions Asked" lifetime warranty which I've utilized once before.
Although I'm questioning the quality of the cord, I still give these earbuds a 5/5 rating. Compared to the Sennheiser CX300, I favor these considerably.
Without hesitation, I recommend the Koss KEB70.
Wouldn't buy them again.
