5 out of 5 eggsGreat headphones for a digital piano

Pros: I bought these headphones to use with my high-end Kawai CA95 digital piano. I am very, very pleased with both the sound and comfort of these headphones. I played for 2 hours the first day I got them and truly forgot I was wearing them.
These are an 'open back design' which results in a sound experience that many describe as the sound being more natural and resulting in sound that better represents the spatial sound characteristics of a piano. Conversely, 'closed back' phones tend to make it sound like the sound is coming from 'within your head'. In addition, because my playing environment is generally fairly quiet I like being able to hear any ambient sounds - like being called to dinner - in the room around me.
Acoustically (to my ears), these headphones faithfully reproduce the sound of my digital piano (which in turn is designed to faithfully reproduce the sound of a Kawai acoustic concert grand). This is the first pair of higher-priced 'audiophile' headphones that I have owned, but compared to the budget phones I had been using there is ABSOLUTELY no comparison.
I did quite a bit of research for these, specifically for use with a digital piano, prior to purchase. One source of good information that I found was the Piano World on-line piano forum (a good source for ALL things piano, by the way). I expect I'm not supposed to link to this forum but I would recommend this site for a number of digital pianist' perspective on headphones.
Some have said that the color and trim of the headphones reminds them of the interior of a 1980's German sports sedan. Well, I couldn't afford a car like that in the 80's (or now, for that matter), so I think the color and design is pretty cool and the build quality seems very good.
In many general discussion about headphones, there are usually 'audiophiles' who recommend a separate headphone amplifier. With my piano at least, I see no need, as I only need to turn the volume control to about 1/3 of maximum to match the same sound level of the piano's native speaker system at full volume. In other words, these headphones seem pretty 'efficient' in my use. My piano has 1/4" headphone jacks I don't use the supplied 3.5mm adapter.
Finally, these headphones come with a 10 foot audio cord that allows me to get up and get music from the cabinet next to the piano. If 10 feet is too much length for your usage, the cord can be replaced with a 4.5 foot version available from Sennheiser or other sources - according to what I've read.

5 out of 5 eggsIncredible Sound

Pros: I've had these for 2 years now, and they are still going strong. Excellent soundstage, buy a ModMic and pair them together to make a great headset.

Cons: Doesn't do my laundry.

Other Thoughts: I bought these when they were still $250, it's an even better deal now.

5 out of 5 eggsFantastic

Pros: Sennhesier Quality/Warranty

Comfortable, good looking

Very long cable and 3.5 mm adaptor

Best over the ear headphones (200-300$) I've used in the past 10 years of using them.

Cons: None so far

Other Thoughts: I got these because they were the best reviewed Sennheiser over the ear headphones besides the 650's (But I didn't have an extra 300 to spend.) I picked these up because of the reviews of great quality and users saying they've the same pair for 4+ years with no problems. And I believe them after using them, absolutely best 200$ headphones I've ever had the pleasure of using.

5 out of 5 eggsAwesome headphones

Pros: -Comfortable, as other people pointed out
-Very clear sound. Not much distortion.

Cons: -More expensive than my current speakers + earbuds combined. But it does sound better and worth the cost.

Other Thoughts: Coming from Moray+ earbuds and logitech speakers, this headphone sounds so much better.

5 out of 5 eggsGreat headphones

Pros: Nice sound stage, great clarity. Not so great for bass heavy music, but that doesn't apply to me. These are also extremely comfortable - I can wear them for many hours with no aggravation.

Cons: None, for me. The only cons I can think of are that others around the listener can hear them, which is not a con for me.

4 out of 5 eggsFantastic Mids, sound amazing...

Pros: Look great, sensational sound...very clear mellow range, not boomy or harsh. Extremely comfortable and adaptive to personal sizing. The white color is more an oyster off white color, very rich looking. Build quality is excellent.

Cons: Generous 10" cable is a blessing and a's a lot of cord to be aware of. May not be for some, no problem for myself.

Other Thoughts: Sound awesome in spite of open back design...personally I like being able to hear outside noise, have conversation without taking phones off. They sound amazing!

5 out of 5 eggsUnparalleled

Pros: I have these paired with an ASUS Xonar Essence STX as well, and they are very pleasing to listen to. I see why these can's are advertised as having a more "natural" and "neutral" listening experience. They really shine on acoustic tracks and easily distinguish between the instruments and vocals. Electronica/trance/techno is very nice on these as well.

Just finished a few hours of Planetside 2, these + the xonar was worlds different from my onboard + HD 485 combo. Everything was so clear and these represented the explosions in the distance well.

Cons: Bass is a tad on the low side but that is adjustable if desired.

Other Thoughts: Very good cans for the beginning audiophile. I would argue the best you can get in the sub $500 market.

5 out of 5 eggsYou have to hear it to believe it.

Pros: I paired these with an ASUS Xonar Essence STX with the primary focus being for gaming. I was absolutely floored when I first tried these. With Dolby Headphone, it was like an entirely new world of gaming. The sound quality is of such high fidelity it sounds just like I'm listening to my 5.1 speaker setup on my TV! If you're a gamer looking for that extra immersion, these are worth every penny.

Cons: None

Other Thoughts: The quality of these headphones will make the quality of your sound source painfully obvious, especially when using Dolby Headphone. Make sure you're giving them a high quality source to truly enjoy them.

5 out of 5 eggsGreat Headphones, but get an optional adapter

Pros: The headphones sound terrific and they look great. I listen primarily to Jazz, however I noticed that since I have had these I've gained a greater appreciation for other genres, specifically classical.

They are extremely comfortable to wear for an extended period of time. There is no fatigue after several hours like I got with other headphones.

The other reviews cover the more technical aspects better than I could so I will defer to the audiophiles.

Cons: Here's my biggest suggestion, get an extended adapter, even if it's ten or fifteen dollars extra.

Here's why: Out of the box these headphones will have a 1/4" connector (big plug for stereo systems) and a 1/8" adapter that connects directly to the 1/4" (what your IPhone uses). So if you are connecting this to your laptop or iphone you are adding the equivalent of a solid 3-4 inch lever on a fragile output jack.

This is such a big oversight I was tempted to give the headphones 4 stars. This is the Sennheiser accountants trying to save a couple bucks per headphone by going cheap on the adapter, nothing more. So I would highly recommend any number of extended adapters that don't put so much pressure on the jacks.

Other Thoughts: These are not for listening to music on a metro. They are an open design headphone so while they sound terrific the sound will bleed out.

I'm still waiting for my amplifier to come in. I may update this review after I head them with additional power.
