It's hard to cram these into the included carrying case
These headphones aren't just good for the price, they're darn good headphones period. I heard a pair of Porta Pros in Best Buy years ago and was wowed by the sound quality. However, since my iPhone had replaced my MP3 player, the only headphones I ever considered buying were those that also doubled as a headset. Back on the rack they went. Fast forward a few years and I see Koss has updated their iconic Porta Pro to include an in-line mic. But would they sound as good as I'd remembered? Amazon had (and has) them on sale so I figured why not take the gamble?
The gamble paid off: I love these 'phones. They sound very similar to my Sennheiser PX-100IIi's but with a bit more bass punch and a little less clarity. I've talked on the phone several times with the Koss' and no one has trouble hearing me. The buttons on the KTC work without issue, though it would've been better if the buttons were raised for better tactile feedback. Other reviewers have alluded to the difficulty in using the KTC, but really it's certainly not any worse than other headset I've tried.
I prefer the sound of these to my Bose QC 15 and the Beats Solo I owned (till the headband snapped) which cost $350 and $200 respectively, and didn't include a warranty. I'll add though that the Bose still excel when it come to noise-cancellation (which is why I bought them).
The headphones are pretty comfortable, and are adjustable not only in size, but ear pressure. They're very light too. Between their weight and grip, I can actually run while wearing these headphones and they won't slide off my head or slide around.
Some people will love the styling of these phones. Others will hate it. I think it's pretty cool that Koss has kept with the design all these years. I was in Paris a couple of years ago too and it seemed like everyone was sporting Porta Pros (seriously, 1/3 people with non-earbud headphones had some) and all the shops carried them).
Bottom line: these headphones sound as good if not better than many that retail for $200+, they're inexpensive, compact, sound great off a portable player, and have a lifetime warranty. If you're looking for a good pair of headphones for your phone/mp3 player, this is the place to start.
*For those who may've read my previous review, I am no longer having issues with the volume control and haven't for months. Not sure why it magically fixed itself.
For that I will continue to use my Porta-Pros, or my bluetooth Porta-Pros.
Although I have given high star ratings to the categories requested, I have given only 3 stars overall. The reason for this is the price point. These headphones are highly overpriced for what you get.
I, however, remain a Koss fan.
All that said, the cord is simply terrible, and it's clearly such a shame that it hampers them so severely. After about 2 months of use my phone started pausing / playing on its own. It evolved into the voice control constantly coming up. On my computer they are unusable because any movement causes them to trigger iTunes or whatever app is registered with the play button remote. Basically, the remote cables seem to have shorted internally. Reading other reviews, I fear this is an inherent design flaw, and even if I spend $20 on a warranty return (all told) I suspect my next pair will have an equally short life span.
I'm not rough on the headphones, but I do use them daily, and bring them around in my backpack.
I'd suggest going with the non-remote pair, or getting clever with a soldering iron and replacing the cord with something more reliable. It's such a shame that amazing headphones like these are so limited by a terrible cord.
