Sony MDR-CD780

So, you should know already if you have the ears of Prince Charles, do not bother to buy this headphone.
The atria are small. The soundproofing is average even though it is closed. I bought this headphone on ebay in Germany and it cost me only 34.01 euros including postage. And I must say at this price it is good. But then, its price is 100 euros public and, I must say that knows quite expensive.

I confess that I find it difficult to rate these headphones as my reference Beyerdynamic DT770 PRO is (250 ohm), pro studio headphones.

While the listing of this headphone is as follows:

Comfort: 4 / 10 (I do not have big ears, but the positioning is poor)
Sound quality: 7 / 10 (10 to 25,000 hz theoretically!)
Construction: 6 / 10 (All plastoche)
General Use: 8 / 10 (Stereo, TV, MP3 player)
Small detail, an MP3 player is not bad at all, but there is a small problem, the cable 4 meters)
Real value for money: 4 / 10
Overall rating: 6 / 10

As for models, I use the following headphones: Beyerdynamic (my favorite brand) DT 150, DT 770 Pro and the collector DT 770 pro 2005 edition limited to 250 copies worldwide as well as quite a few others, but I Again, the reference to me what are the Beyerdynamic headphones mentioned above.

In conclusion, with the experience and for the price I paid, it's a great headphone, but at a price of 100 euros, then I say no, too expensive for the overall quality of this headphone that I call Hi-Fi headphones.

There are three for me type of headphones.

1: studio headphones (pro), they are not very numerous, the two brands differ Beyerdynamic and Sony MDR 7509 are famous.

I can see fans of the Sennheiser I argue that there are HD 250 Linear or even the HD 265, yes, but what little comparont be, the two range from 8 to 10 Hz at low frequencies, c is not bad, but ..... I personally own the first city and it's good no more.

In addition, a headphone for me must be able to reproduce studio audio spectrum ranging from 5 to 35,000 hertz.

2: Hi-Fi headphones (high fidelity) they range from 10 to 25,000 hertz.
3: stereo headphones, they will them from 20 to 20,000 hertz.

Below its frequency is the brol, anything.

Well, that's up to you for that price, there's more. But keep in mind that a headphone superb quality usually costs except "good deal on ebay" between 125 and 220 euros or even more.
