Product Description

From the Manufacturer

The DT 660 is a closed headphone that attenuates ambient noise effectively--and no sound from the headphone will leak, interrupting those around you. It's a great way for the audiophile to create their own private listening experience. The DT 660 features a sophisticated sound with a detailed reproduction of the deepest bass and brilliant highs. The 90° swiveling ear-cups and softer yet sturdy materials for the headband and the ear pads ensure outstanding levels of comfort. The fold-away design makes it easy to store and transport.

Featuring a closed-back design for private listening in public environments

Closed Design for Increased Noise Isolation with Swiveling Earcups

The DT 660 features a closed-back design for private listening in public environments. Ideal for portable devices, the DT 660 delivers the German quality of an audiophile headphone that's just as good for your media player, music-playing smartphone, or laptop as it is for virtual surround sound listening on your demanding home stereo equipment. Anywhere you need high-resolution audio performance, the DT 660 delivers with immersive, isolated sound and wearable comfort.

Easily folds into a compact form to carry in your backpack, suitcase, or bag

The ultra-soft earcups are ideal for extended periods of wear, so you can enjoy an entire concert (or two) in complete comfort. An adjustable headband lets you achieve the perfect fit, and the earcups swivel a full 90 degrees for listening and positioning convenience.

Dynamic Transducer for Increased Fidelity and Performance

Without exception, beyerdynamic manufactures the dynamic transducer systems that go into their headphones in-house. From the magnet and diaphragm to the careful wiring and circuitry, beyerdynamic controls quality at all levels of manufacturing, ensuring superior engineering in their headphones down to the smallest detail.

An extremely strong neodymium magnet system offers the DT 660 highly detailed sound reproduction quality, is mechanically very robust, and needs only a small amount of operating voltage which increases efficiency. This increased efficiency also leaves the DT 660 with greater power reserves for dynamic, undistorted sound that especially compensates well for low-spec mobile devices such as portable media players that often can't perform at the same level as dedicated home equipment. The extremely lightweight 32 Ohm voice coil provides transparency and increased impulse fidelity.

Fold-Away Design

The convenient folding earcup design of the DT 660 helps it take up less space while on the move, easily folding into a compact form to carry in your backpack, suitcase, or bag.

Sound quality is great. I use these with my Ipod and Sony mp3 Players, I just needed a booster to get the volume I like Now the sound quality is REALLY great.I have several high end headphone sets,Bose,Sennheiser etc. These are studio quality for a great price. For sure well worth the cost.

4.0 out of 5 stars Great set of cans after some burn-in!, February 5, 2010

By 

Kool Aid "mgm2000on" (Huntsville, Alabama) - See all my reviews

This review is from: beyerdynamic DT 660 Premium Headphones (Electronics)

Well, let me start by saying that I was choosing between two sets of cans. It was either the Sennheiser HD280 or the Beyerdynamic DT660s that which I purchased. With that said, if I had a set of HD280's to demo, I could have possibly chose those, else I would have been purchasing based only on reviews. But, I actually got to demo the DT660s.

At first listen (out of the box) the DT660s sounded good, but they seemed a little lame in the low frequency department and the mid-range and highs were screaming in comparison. However I read that they require a bit of burn-in prior to them reaching their potential. After the first night and about 14 hours of burn-in, I gave them a listen. Not much difference, but they had woken up a bit and sounded much better. The sound was a bit warmer and the bass was present. I've now clocked about 160 plus hours of burn-in and listening time and the sound is fantastic. I'm very pleased with the progress. The tones are very even with good low frequencies, buttermilk mid-range, and silky highs. They also provide a pretty good soundstage for closed cans. Beyer pulled off the all time caper with that feature. They started out a bit harsh, but now they've settled in pefectly. These headphones aren't for the intense bass seekers in my opinion. They're well balanced and provide an honest presentation, i.e., if it was recorded that way, you'll hear it that way. However, they'll cater more towards the jazz, classical, and acoustic audience in my opinion. They do the bass catered genres (hip-hop, R&B, techno) quite well, but I don't think that is where they shine. I've blessed them with some Wynton Marsalis, Hampton Hawes, Lee Ritenour, and Grover Washington Jr. for jazz, The London Symphony Orchestra (Classical) and some Canton Jones (Christian Hip Hop/R&B sound) and they've performed very well and with great accuracy. I can only expect them to get better.

As always, I only listen to tracks at 320kbps or better (lossless format) to get the best sound out of my components that I can. I've used these on my Ipod (direct) as well as with a Boostaroo Amp. These are 32 Ohm impedance cans, so they did do well on the Ipod direct, but the Boostaroo brings them out much better.

These phones also isolate sound from the outside, and keeps your music in very well.

Comfort may be an issue for some because these are large phones and a bit on the tight side for me, but overall, the longest I've worn them is for about two hours before taking a break. They apply a little more pressure to my upper jaw (right below my temples and beneath my ear lobes) than I would prefer (not painful, just annoying), but at least the padding is soft and I'm used to the feel now. If they were perfect in the comfort arena, I'd give them a 5 star rating.

I've tried some of the higher-end Beyerdynamic headphones, like the DT 880, and they do sound amazing. They're certainly better than these 660s, but they're also quite a bit more expensive. For me, these headphones are the right combination of sound quality and price. It was also important to me that these are closed-back, as I need to use them in situations where I want minimal sound leaking into my surroundings. Despite their size, they also feel very light on my head.

I have compared these extensively to a couple other different headphones. First, the Sennheiser HD 280 are much tighter-fitting and are therefore much better at ambient sound attenuation, although the sound quality of the Sennheisers probably isn't as good. Second, I bought these Beyerdynamics at the same time as a pair of Sony V6s. For the price (<$100), these Sony headphones are amazing. They're very comfortable (especially with the upgraded Beyerdynamic ear pads), compact, and sound very natural. I use my 660 for home listening, and my V6 at my desk at work where things get tossed around a bit more.

Finally, I should point out that I bought these 660s for about $135, which looks like a great deal considering the current price. If you're already thinking of paying in the neighborhood of $200 for these, then you should consider laying out a bit more for either the DT 770 (also closed-back) or DT 880 (open-back) models.
