I'm usually a sound-first guy, but when it comes to evaluating headphones, comfort is a very close second. So even when I love the sound of a headphone, if they start to hurt my ears after a half an hour, that's a deal-breaker.

That's why I'm happy to report on a remarkably comfortable and great-sounding headphone, the MrSpeakers' Mad Dog. That's an odd name for a headphone maker, but MrSpeakers' Dan Clark started out as a speaker designer. Now he extensively modifies Fostex T50RP headphones, a headphone that I've never cared for. Clark transforms … Read more

I'm a lucky guy, I've heard most of the world's very best headphones: Sennheiser's HD 800 and their legendary Orpheus, the Audeze LCD 2 and 3, the Stax SR-007 ($2,600), SR-009 ($5,200), and now I'm spending quality time with Hifiman's flagship HE-6 planar magnetic headphones. I've long admired Hifiman's designs, starting with their very first model, the HE-5 back in 2009. The HE-6 looks nearly identical to Hifiman's current HE-4, HE-400, HE-5LE, and HE-500 headphones, but the HE-6 is heavier (502 grams), and it feels like it's built … Read more

Head-Fi is a national headphone club, and I went to the local meeting in Babylon, N.Y., last Saturday.

The vibe was friendly, and it was great to hear Head-Fi members' home-built gear, but there were a few surprises popping up from the headphone and electronics manufacturers in attendance.

Logitech Ultimate Ears' Personal Reference Monitor in-ear headphones feature a new twist on custom-molded-to-your-ears headphone design. Lots of brands now make custom in-ear headphones, and Logitech's have been among my favorites for years, but the upcoming Personal Reference Monitor takes the personalization to the next level. Once your ear canals' &… Read more

Most headphones have tiny dynamic drivers, basically miniaturized versions of the drivers used in box speakers. The Audeze LCD-2 features a completely different technology: it uses thin-film planar magnetic drivers. I first checked out the Audeze LCD-2 headphones last year and absolutely loved them. The company redesigned the drivers to produce even better sound, made the earpads thicker, and now covers the headband in real leather. I found the sound improvements of the revised model significant enough to warrant a new review.

The styling is bulky and retro, but the quality feel of the LCD-2 is more than skin deep; … Read more

I cover a wide range of headphones on this blog, everything from the $40 Deos earbuds to the state-of-the-art Woo Audio WES headphone amplifier ($4,500) and Stax SR-007Mk2 headphones ($2,410). I've written about a lot of great headphones priced between those two extremes.

The common thread to all of the headphones I cover here is they all have excellent sound quality, but if there's one thing I know about the audio business, it's that most people don't prioritize sound quality, even when a better sounding product fits within their budget. With headphones, most buyers … Read more

I've never heard anything quite like the Audeze LCD-2 before. This headphone somehow produces extraordinary clarity, openness, and articulation, but without exaggerated detail or annoyingly overdone treble. The Audeze LCD-2 is a game changer; no wonder it's getting raves from the online high-end mavens at Head-Fi. Audeze's co-founders, Alex Rosson and Sankar Thiagasamudram, are onto something.

The headphones feel great in your hands. Build quality is robust, but the design is nowhere as sleek as Sennheiser's high-end headphones. The LCD-2's impedance is 50 ohms, and the maximum power handling is a remarkable 15 watts, which corresponds to a superloud 133 decibel output! You'd be hard pressed to blow this headphone up by playing it too loud. The LCD-2's tonal balance is noticeably warm, but I never felt it was smearing detail or lacking in resolution. It also sounds great at quiet listening levels. Sure, one of the advantages of headphones is you can play music as loud as you want, but it's still nice to have the option of listening low, without losing detail or presence.

The LCD-2's unusual technology (planar magnetic, or orthodynamic) is currently only used by one other headphone manufacturer, Hifiman, and I raved about its HE-5 headphones last year. The LCD-2's huge headphone drivers (6.17 square inches each) are many times the area of any dynamic headphone I know of. Audeze's very large drivers project sound over most of your outer ears, and that may be the reason why the LCD-2 sounds more speakerlike than other headphones. It weighs a rather hefty 19.4 ounces (550 grams), but I found it comfortable over very long listening sessions. The LCD-2 is handmade in the U.S., with real lambskin leather-covered earpads, and real Caribbean rosewood earcups.

The LCD-2's headphone cable is detachable, via very secure mini-XLR plugs, and is therefore user replaceable. I opted for a Chain Mail 8, an audiophile upgrade cable from ALO. It seemed to enhance everything about the LCD-2's sound, which was awfully good with the stock cable.

The LCD-2's big drivers make bass, oh boy, do they make bass. If you really want to hear amazing bass, you have to get "Kodo: The Heartbeat Drummers of Japan" CD. The drums' big sound is beyond the abilities of most headphones, but here, over the LCD-2, the drumbeats were clear and powerful. Not the sort of flabby, thick, or overdone bass you get from DJ headphones, no, I'm talking about pitch-accurate, highly defined bass that also digs deeper into the very low bass regions than other full-size 'phones.… Read more

I've probably listened to and reviewed a thousand speakers, and truth be told, the majority of them never sound like live music. They sound like speakers.

The "problem" with box speakers is that you're always aware the sound is coming out of a box, but Magnepan speakers don't have a box. And they don't have dome tweeters or cone midrange or woofer drivers, either. Magnepan technology is radically different than what you find on box speakers, so the 1.7's sound "floats" free of the speakers themselves.

The new Magnepan 1.7 ($1,995 per pair) looks a lot like the model it replaces, the 1.6, which was regarded by many of the world's high-end audio critics, including me, as one of the greatest less-than-$2,000 speakers on the market. The 1.6 stayed in the line for more than 10 years, and I have every reason to believe the 1.7 will be a standard bearer for just as long. And speaking of value, Magnepan also offers a factory-direct $599 (per pair) panel speaker, the MMG. The technology isn't as advanced as the 1.7's, but it's miles ahead of any other $599 speaker I can think of.

The 1.7 panel is 64.5 inches high, 19.25 wide, and just 2 inches thick. Magnepan builds all of its speakers in White Bear Lake, Minn., and almost all the 1.7's parts that aren't fabricated in-house are sourced from U.S. suppliers. I reviewed the 1.7 for Tone Audio magazine, where you can read the complete review.

The 1.7's technology is unprecedented for Magnepan; the speaker is the company's first "full-range ribbon" design. It's also worth noting that what makes a well setup pair of 1.7s so special isn't just something that only dyed-in-the-wool audiophiles would notice; pretty much anyone with ears will immediately grasp what's going on. Their box-free sound is astonishing.… Read more

Every year product life cycles in the consumer marketplace grow ever shorter and we see ever faster turnover in cameras, phones computers, and so on. On the audio side, the latest and greatest receivers become yesterday's news faster than you can say "HDMI 1.4." It seems like no receiver can stay current for more than a year or so.

Speaker companies show a little more restraint and "refresh" their lines every few years, but even then new models rarely demonstrate actual performance improvements over the previous generations' models. Speaker manufacturer Magnepan doesn't play by those rules; it invests years of development in each of its models before introducing a new speaker. It has to sound better--a lot better--than the outgoing model before it's released to the world.

And not just in the opinion of the designers. New-model Magnepans undergo extensive "blind" listening tests with a wide range of audiophile and non-audiophile listeners (the listeners don't know whether they're hearing the old or new model). The new speaker must consistently score better than the old model before it goes into production.

When I first heard the Magneplanar 1.6 back in 2008 I said it was the best under-$2,000 speaker on the market. Incredibly enough it was 10 years old at the time! The Magneplanar 1.6 has stayed in production for 12 years, but now it's about to be replaced with the new Magneplanar 1.7.

Magnepan, based in White Bear Lake, Minn., builds nothing but panel (boxless) speakers. Not only that, Magnepan designs forgo conventional dome tweeters and cone-type woofers. As I pointed out in my August 14, 2008, blog that's why the company's Magneplanar 1.6 speaker mostly avoids sounding like a speaker. The speaker earned the top position in my Top 10 greatest audiophile speakers blog earlier this year.

The new Magneplanar 1.7 is also a flat-panel design, 64.5 inches tall and a mere 2 inches thick! The new speaker looks a little more contemporary, thanks to its aluminum, wrap-around edge molding. The old model was a two-way design, with a 48-inch-tall aluminum ribbon tweeter and a 442-square-inch mid/bass panel. The Magneplanar 1.7 is a three-way design, with a woofer, tweeter, and super-tweeter. The super-tweeter comes in around 10,000 hertz and is said to produce wider dispersion and better-resolved treble than the Magneplanar 1.6 did.

The other big difference is the Magneplanar 1.7 is a "full-range" ribbon design.… Read more

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. … Read more
