Purchased two units. One for my wife and one for myself. My wife is using hers and loves it. I have not used mine as in hindsight I should have purchased the Porta Pro.
We were using the UR20 and upgraded to the UR29 because it offered volume adjustment. After trying my wifes UR29 I find that it gets too hot around the ears because it is totally enclosed. The Portoi Pro is open air and allows heat to escape. Next time (Black Fri 2019) there is a major sale I would try the Porta Pro for myself.

Excellent for the price
Overall
I purchased a set of these eight years ago looking for something better than cheap,disposable headphones. I was shocked at the sound quality and still amazed at the clarity of sound while reducing outside noise. They have held up great, even surviving a tour in Iraq, until just recently. The sound is still great and they function properly, but the material for the ear cushion is breaking down and leaving me covered with black flakes. Time to get another set. Despite this issue, I would gladly recommend these headphones to anyone!

Great sound, terrible bracket
Overall
These UR29 have great sound, very comfortable and I love that you can adjust the volume on the cord. But the weak point is the bracket that connects the earpiece to the headset. The plastic breaks if you are not super careful when you place them on your head.

Excellent features, excellent price
Overall
Long time UR29 user at work and home. By far, the Koss UR29 has out-performed any other headphone I have purchased for its durability, extended-use comfort, sound quality, low leakage of sounds yet allowing muffled sounds in for co-worker/cohabitant communication.
Pros: Comfort, sound quality, durability
Cons: Have yet to find a Con

Outstanding sound for the price but...
Overall
For the price of these, you will be very hard pressed to find headphones that sound as good so I can't really complain. I have bought a few of these, 1 for me and 1 for someone else and they both shorted out at the jack and 1 also had shorted out at the headphones so be cautious not to make any sudden tugs on the cord. As long as you are very careful with the cord, you should have no problems. Other than that, they do sound as good or better than some $100 headphones from other brands that I have listened to.
Pros: great sound, good bass, comfortable
Cons: the cord

Excellent product
Overall
These are the best headphones I had. Great sound, great bass, real isolation of background noise. I use them on transatlantic flights and wear them for hours without any discomfort.
Pros: Great sound, very comfortable, real isolation from ambient noise
Cons: Size !

very good value, comfortable
Overall
I have had a pair of these for around 10 years, and they have been great! They are just worn out (I’m gentle with headphones). So I am got another pair. I am going to use the new ones in my project studio, because I am tired of watching people beat up on my expensive headphones. Plus these a very comfortable. Sound quality isn't super detailed, but if you want perfect, pay for it. But for general use, and a good deal these are it. Volume control, long single entry cord, comfort, and none fatiguing sound make these more than worth 30 bucks. Also most pro gear will behave better under the 100 ohm load vs. 32 and 16 for example.
Pros: comfort, style and features
Cons: treble definition

UR29 = Beats Who?
Overall
These cans are a steal at the $20 I paid. I have heard nothing in this range that sounds as good. I have cans that cost over 5 times the amount that the U29's cost, and while they are better, these hold their own very handily. I suggest you apply some small strips of tape over the reflex slots at the top. That will increase the mid-bass response. Other than that, you simply cannot find another pair of under $50 phones that sound this nice. How do I know this? I am a mastering engineer. I am hunting for the titanium set as well, because if these sound that good, I'm very interested in hearing those as well.
Pros: Extremely Flat Response! Excellent range without distortion.
Cons: AT this Price absolutely NONE!
