This head phone suck compare to my shure scl5($250.in ebay). It look like a cheap head phone. The scl5 is a lot better than hd650 in any frequence. The price is too high for such headphone like this. It should only cost $100.00 at the most.

every thing

I used them everyday since 6 month from now and they are just superb. The only bad thing about them is the cable that somehow always gets stuck on something ha ha ha so strange. As a beginner audiophile they are solid entrance to the audio world.

The Sennheiser HD 650s are a solid pair of headphones for at-home use.

You will never regret purchasing these they are a bargain at twice the price ... Btn Read More

Great sound They took the HD600 and gave it some Bass and an overall smoothness that really makes it shine ; A lot of Audiophile Grade Headphones are accurate but dead and I include the HD600 in that class but the HD650 does well with almost all genres of music and the fact you can take it...

An unusual feature of the Sennheiser HD 650 headphones is that the cables can be unplugged for easy replacement should the conductors ever fracture under physical stress in future years. They are quite thick cables, too, and three metres long, terminating in a 6.5mm plug.

Superb no-compromise sound; Very comfortable to wear; Main plug is 6.5mm; replaceable cable ensures long life

Sensitivity too low for some MP3 players

The Sennheiser HD-650 is an old flagship of the company now replaced by the HD-800s. Though said new flagship is almost triple the price. The HD-650s retail at 499 US Dollars. Like most things, these do go on sale but rarely.

You can tell these hardy Sennheiser veterans mean business. Metal construction gives a vice-like fit on your dome and speaks of their ineffably high-end sonics. You'll need an adaptor to plug them into an iPod; these are built to be part of a nice little home hi-fi set-up.

Sound is flat-out the best here; Across a full gamut of musical styles the HD 650s serve up smooth, subtly conveyed sound, but when you want them to kick out the jams, these metal mothers don some large-style boots.

The open-backed design leaks sound like a sonic sieve, so these are totally unsuitable for wearing on the tube, unless you enjoy "chin music" courtesy of your fellow passengers; Given that they're thus intended for long, immersive home-listening sessions they could also be more comfortable.

A stunning piece of kit that'll bring the very best out of your CD collection

Incredible sound quality whatever you throw at them; great build quality

Pricey; only for hi-fi nuts

Music is a very personal thing, even more than movies, and games for that matter. People can be really particular about their kind of music and more importantly, how natural it sounds to them.

These headphones are probably not for you! They will produce excellent quality sound (one of the very best headphones at any price) but they really need a proper headphone amp and an excellent source to make the most of their potential and most people have never heard of a headphone amp and use mp3s...

Lets you hear your music at it's best

Just be sure your music's best is good enough! Really NEEDS a headphone amp
