Summary: I am not an audiophile, but I purchased a good pair of ear phones a few years ago and I can't go back to phones with poor sound quality. That said, the MDR-D777lp was my first foray into the ear cup design after years of sticking with the in-ear phones. These headphones are comfortable to a point- after about an hour of usage, the cups may begin to irritate your ears.
Summary: I bought these for $20 and have been using them for a while now (about 4-5 months). Sound quality is solid. Everything from the bass to the highs is crystal clear. The headphones cancel out external noises pretty well and it's nice that they can fold up. Now for the cons. The chord is short, which can restrict your movement depending on your setup. Now if this was the only problem, I'd easily give it 5 stars since at $20 it'd be a bargain.
Summary: For the price I payed (25$), I got way more then I expected. Of course, compare this to the Bose series, which I also tried, Bose wins hands down, they also come with a minimum retail value of roughly 5 times this for their cheapest model. My sources for comparison are the Bose Quiet-Comfort an Apple/Ipod headphones.
Summary: I bought these mainly because they were only $25 and they had a very high list price. Because of this I assumed they would be mostly high quality but were selling cheaply because of build issues. After trying them out, I would say they are worth maybe $35 but definitely not their list price. My first impressions are that they look very nice. In the pictures they look silver and black, but in person they definitely are more of a grayish, platinum color.
Summary: Quick Review Pros: Good clean quality Portable, look cool Only $30-$40 on amazon cons: Bright sound Hard clamp on the head, can become uncomfortable and even cause headaches after 20-30 minutes. So-so build quality, may break easily. Definitely worth $30, probably not more than $60, due to the discomfort. The triports sound slightly better and are much more comfy.
Summary: Alas, we get what we pay for (when we're lucky). These are fine as $20 headphones to give the kids, but the $100 list price is truly a joke! I'm a collector of moderately priced cans, and after comparing these to my Sony MDR-V6s and MDR-V600s, and Sennheiser HD-202s, PX-100s, EH-150s, HD-477s, and HD-280s, I'd say they are closest to the HD-202s in sound character.
Summary: These things won't be winning any huge awards, but they are a great set of cans for a very low price-point. They have extremely crisp highs, and they are much more efficient than my other headphones. (The same volume setting on both headphones, these are louder) They do a great job at noise-cancellation, even though the audio bladder switch on the side does nearly nothing.
Summary: Wife has some bose headphones. I thought I would save a few bucks and try these. Yes, they are a great deal, they sound fine but they are no comparison to her bose. So if you looking for something that is fine but not worry about them getting broken or stolen. They will do.
