The Audiophiliac

I've recently reviewed most of the contenders for the world's best headphones: the Audio Technica ATH-W5000, Denon AH-D7000, Sennheiser HD 800, Grado PS-1000, Ultrasone Edition 8, and the best headphones I've heard so far, the Stax electrostatic SR-007Mk2. I listened to the Stax with the Woo Audio WES headphone amplifier. If you want and can afford the best, go for the Stax-Woo combination.

But now I have yet another headphone to check out, and this one is a very different-sounding design. Oh, and it's less than half the price of the least expensive of those models!

It's called the Hifiman HE-5, and it uses planar-magnetic drivers to create sound. A planar magnetic driver is a large, flat Mylar diaphragm, coated with superthin aluminum, suspended between rows of slender bar magnets. The HE-5's diaphragm is therefore driven over its entire area, which dramatically reduces distortion; conventional dynamic headphone drivers are "driven" by a voice coil on the outer edge of the diaphragm, so the inner portion is more likely to distort.

The HE-5's driver is similar to the Stax electrostatic 'phones in that way, but the HE-5 doesn't use the bias charging scheme that all electrostatic headphones use, which also means the HE-5 can be used with standard headphone amplifiers. The Stax cannot.

The HE-5 is incredibly detailed sounding, but at the same time it's very smooth and laid back. Swapping between the HE-5 and the Sennheiser HD 800--considered by many to be the world's best dynamic headphone--the two headphones are opposites. The HD 800 is brighter, crisper, with more apparent treble detail; the HE-5 is softer, warmer, and more natural-sounding.

The Grado PS-1000 headphone

The Grado PS-1000, Sennheiser HD 800, and Ultrasone Edition 8 full-size headphones all sound amazing. They're all expensive to buy, but if you listen to headphones with your hi-fi or computer, they might be worth the investment. Which one is right for you?

That depends. First, they sound very different from each other. To get the full scoop, read my CNET reviews of the Grado PS-1000, Sennheiser HD 800, and Ultrasone Edition 8 headphones.

My personal favorite was the Grado, as it was the most exciting to listen to. It seemed to bring out details more, and its dynamic impact was simply more visceral than the other two headphones. It worked well enough with my iPod, sounded acceptable with my Onkyo TX-SR805 receiver, and best with my Woo Audio WA6 Special Edition headphone amplifier.

The Ultrasone Edition 8

Which reminds me, if you're going to spend big bucks on a headphone, check out dedicated headphone amplifiers. I've blogged about Woo's amps many times, and they offer models starting at $470. I will try to get around to covering other brands soon.

The Ultrasone was the bass champ of the three headphones. If you love bass and you want to feel it, check out the Edition 8. As I said in the review, it gets closer to the full sound of a large floor-standing speaker than the other headphones. It's also the most iPod/MP3 player-compatible deluxe headphone I've heard. I couldn't believe how good it made my iPod sound.

If you have ears, prepare to open them now.

I've just reviewed a bunch of contenders for the world's best full-size, over-the-ear headphone: Audio Technica ATH-W5000, Denon AH-D7000, Grado PS-1000, Sennheiser HD 800, Stax SR-007Mk2, and Ultrasone Edition 8 headphones--and all boast higher MSRPs than the JH Audio JH 13 Pro in-ear headphone.

Sure, full-size headphones can be used with iPods and MP3 players with varying degrees of success, but they're a lot more of a hassle to lug around than the JH 13 Pro. Honestly, I prefer the sound and comfort of over-the-ear models compared with in-ear headphones. Then again, the JH 13 Pro is a very different type of in-ear design, it uses six drivers--two woofers, two midranges, and two tweeters--to lower distortion compared with other in-ear designs. It's a difference I can hear.

The JH 13 Pro's resolution of fine detail is extraordinary, drums sound more realistic than I've heard from any other type of headphone. The JH 13 Pro is "fast," cymbals' shimmer and sparkle the way they do in real life, and when a drummer whacks his sticks against the drums' metal rims, the sound is more realistic. Dynamic oomph and slam are the best I've heard from an in-ear headphone.

The JH 13 Pro's bass goes deeper than any in-ear headphone to date, but it's the way these headphones decode palpable bass textures that's highly addictive. Electric, acoustic, and keyboard basses sound more different from each other with the JH 13 Pro. Switching over to Monster's excellent new Turbine Pro Gold in-ear headphone ($299) is startling, the Turbines sound mushy and muddled by comparison. The Monster has more mid-bass fullness, which some listeners may prefer. I do not.

The JH 13 Pro's midrange clarity is radically better than any in-ear 'phones I've used to date. Its bass, midrange, and treble are better balanced and accurate than what I'm used to from in-ear designs.

Germany has the high-end headphone market covered, as Beyer Dynamic, Sennheiser, and Ultrasone are all headquartered there.

Ultrasone is the newcomer of the group, but it's hardly new. It was founded in 1991 in Tutzing, close to the Alps in southern Germany. The headphones are manufactured in the U.S., Germany, Austria, and Taiwan.

Ultrasone has just announced a new flagship model, the HFI-2400 ($329). It features Ultrasone's S-Logic technology that promises to create "natural surround sound" by reducing pressure on the eardrum up to 40 percent. The new headphone also features ULE-technology that reduces electro-magnetic radiation by 98 percent compared with conventional headphones.

The HFI-2400 is a foldable, open-backed design that delivers a wide soundstage to the listener. The headphone comes with a removable 10-foot cable, a velvet carrying bag, and an Ultrasone demonstration CD. The HFI-2400 will be available in late October or early November.

Headphone lovers of the world unite! We now have our own wiki, Wikiphonia.

Headphones are hugely popular now, but they were around long before "i" and "Pod" ever got together. The history is long and deep, and Wikiphonia is a fantastic resource for anyone who wants to know more about headphone technology and related information.

Headphone geeks are a breed apart from audiophiles as I know them, but they're an even more intense bunch. One of the great things about headphonia is you can get in pretty deep without a big investment. Hard-core types like to build their own headphone amplifiers.

Wikiphonia has an entry that covers 1970s era USSR copies of Western headphone technologies and designs, "The copying was done out in the open, probably and correctly, they figured no one would start a conflict with a superpower over a few headphone patents."

For me, it all started with Sennheiser's HD 414. Its bright yellow earpads were super cool, and the sound was awesome. Back in the early 1970s it was a really big deal, a giant leap better than anything I'd ever heard. You can read all about it on Wikiphonia.

Lucky me, I've reviewed most of the world's very best headphones, including the Audio Technica ATH-W5000, Denon AH-D7000, and Sennheiser HD 800. But now there's something even better: the Woo Audio WES headphone amplifier ($4,500) and Stax SR-007Mk2 headphone ($2,410). The complete review can be found on the Home Entertainment Web site.

Yeah, it's a lot of dough, but the Woo/Stax combo creams the other contenders for world's best headphone sound, and the pair goes for less than the price of a world class, high-end camera, like the Canon EOS-1Ds Mark III. The camera's great now, but in a couple of years it'll be hopelessly out of date. Great audio is simply a better long-term investment.

Stax headphones use a very different operating principle than dynamic headphones (pretty much every headphone from lowly earbuds to full-size headphones are dynamic designs). Stax has been making electrostatic headphones since 1960 in Japan, and the company's current flagship model, the SR-007Mk2, is what I'm using with the Woo WES amplifier. The Stax is a big and comfy design.

The Woo WES is an all-triode tube drive, fully balanced design; the prototype unit I'm reviewing has a total of 10 tubes (four EL34 power tubes, four 6SL7 drive tubes, and two 5AR4 rectifier tubes), but production models will have 11 tubes. It works with Stax and Sennheiser electrostatic headphones only. The machined, all-metal dual chassis is beautifully crafted.

The WES, like all Woo amps, was designed by Wei Wu, and handcrafted in Woo Audio's factory in New York City. Each WES will be built to order over a four-day period; it's slated for release in October 2009. The preintroduction price is $4,500, and full retail is expected to be $4,990. Woo prices start at $470 for the WA 3. All Woo Audio electronics are sold direct from the factory, the waiting list is three to four weeks.

A look inside reveals no circuit boards; all wiring will be "point to point." That's a very expensive way to manufacture amplifiers, but Woo Audio thinks point-to-point wiring makes for better-sounding amps. The amp also features handmade inductors, and even the machined cone feet are designed specifically for the WES.

The clarity of the Woo/Stax combo with acoustic jazz mimics the way live, unamplified music sounds in a good concert hall or club. The Woo/Stax is the closest thing to being there I've heard to date.

On Thursday night in Manhattan, Mr. Monster himself, Noel Lee, introduced a handful of journalists to his new top-on-the-line in-ear headphones, the Turbine Pro.

I'm a huge fan of Monster's original Turbine at $150. It's easily my pick for the best bang-for-the-buck in-ear. But the new Turbine Pro at $250, due out next month, is better. The Turbine remains in the line.

I was listening to a hand-built prototype Turbine Pro (the builder must have really tiny hands) and I have to say, the new baby has even greater clarity, more accurate bass, and sweeter treble. It's a more refined sound. Not that the standard Turbine is a slouch in those departments, but the Pro is just better in every area.

Lee also demonstrated his newly designed ear tips, which were extremely comfortable and provided improved isolation from external noise.

The headphone's technical details weren't disclosed. So for now I can't really say why the new ones are better. More to come on that.

Let's face it, headphones always sound like headphones--that is--they never really sound like speakers.

Headphones "squirt" sound directly into your ears, but the new AKG K 702's much-larger-than-average earcups allow the drivers to be placed farther away from your ears, so the sound seems less direct. This headphone was designed for recording engineers and studio use, and the sound quality is right up there with some of the best headphones ever made. Priced at $540, it's not cheap, but it's not at all out of line for what you get. This blog is a preview of my upcoming full CNET review.

I found the K 702's expansive sound hugely appealing; that's why it sounds less like a headphone and more like speakers in a room. Not the same as, but less headphone-like than most.

The AKG K 702 is, in fact, the professional version of the consumer K 701 model that came out a couple of years ago. That one received raves from the audiophile press, including me, so naturally I had even higher hopes for the K 702, but it's essentially the same design as the K 701. The K 702 is matte dark blue (looks black to me) instead of gloss white and features a detachable cable.

Thanks to the way the K 702's real leather/metal wire headband distributes the weight of the 'phones evenly across your head, and those large, extra soft velour covered cushions, you can wear these headphones for hours at a time and they'll remain nice and comfy. Build quality, durability, fit and finish are all first rate.

I've made the point in previous blogs, but to get the best sound from high-end headphones plug them into a high-quality headphone amplifier. Sure, the K 702 sounded fine plugged into my Onkyo SR-TX 805 AV receiver, but the headphone was sweeter and prettier sounding with my Woo Audio WA6 SE tube amp ($1,050). Then again, the K 702's sound over my ancient 15GB iPod wasn't too shabby.

Sure, most AV receivers have "good enough" built-in headphone amplifiers, which are fine for occasional listening.

But if you regularly listen to a decent set of headphones over your home theater system or computer, I recommend moving up to a high-quality headphone amplifier, like Benchmark's DAC1 USB ($1,275).

AV receivers' headphone amps, even on $1,000+ models either sound anemic, with little or no bass, or they're muffled sounding things. Whenever I review high-end headphones, I always plug them into an iPod, AV receiver, and a dedicated headphone amplifier, just to see how they perform in different contexts. But headphones always do their best when plugged into a good headphone amp.

Benchmark is one of the few manufacturers of professional audio gear that has consistently wowed audiophiles. The company offers a range of headphone amplifiers, and I reviewed the Benchmark DAC1 USB when I tested the Denon AH-D5000, Grado GS-1000, and Ultrasone Edition 9 luxury headphones for Home Entertainment magazine.
