Do you have some questions about headphones? The article below is dated, but it may shed some light... (by Bill K)
Headphones have been around a while, but they originally were only seen in the recording studio or in the home! Now you see them everywhere these days! First walkmans, then discmans, now MP3s, iPods, and iPhones. Computers at work and on the road, and even portable DVD players! As the price of portable electronics has come down, more and more people are re-discovering the detailed sound quality headphones can offer. And, in these economic times, good quality full sized headphones can be your ticket to affordable listening at home. As the owner of a specialty CD store for many years, I wish I could have had a dollar for the number of times I heard a positive comment about their listening experience from someone finishing a session at one of our CD listening stations. I know I still can be amazed at the detail I hear through headphones that eluded me when listening with standard speakers. It is not our goal to sell headphones solely to audiophiles, but rather to introduce the rest of you to the concept of enjoying your music through affordable higher quality headphones.
Headphones are the least expensive way to listen to high quality music reproduction from your musical sound source. You would probably have to spend five to six times as much money on speakers to get close to the equivalent quality of sound you hear through headphones. Unfortunately though, most headphones sold these days are sold in sealed containers at department stores for the cost equivalent of one or two CD's. Or even worse, you are listening to the headphones they gave away with your portable player! Frankly, most of those headphones are lacking in sound quality! Stereo Review's Ken Pohlmann wrote in an article back in the 90's about portable CD players in which he said... "The headphones supplied with CD portables vary widely, and their sound quality is almost always inferior to the signal quality available at the headphone jack"! The same is still true today with most portable players! And don't get us started about the cheap headphones many people have lying on a shelf collecting dust! If you had good headphones, you might be torn between listening to them rather than tinny sounding speakers placed awkwardly in an out of the way corner. We have been selling headphones since 1988. In our quest to become a "Quality" headphone specialist, we have spent much time over the past decade researching and comparing headphones for sound quality, comfort, and price. In our research, we have found some spendy headphones from Sennheiser and AKG consitently garner positive comments from audiophile reviewers. Our favorite audiophile headphone manufacturer,Grado, is consistently highly rated for sound quality by the audio experts, even at some lower price levels! And Ultrasone is a relatively young company, but their goal of making sound quality a feature again is refreshing, (in this day and age, many mass marketing companies have abandoned sound quality for styling and low prices). Another younger company, Equation Audio, has caught our ears. Besides good sound and build quality, they have a detachable cord, (a feature we would like to see more manufacturers utilize as it helps avoid bad connections which can develop when you inevitably accidentally yank on the cord). Given the huge growth in the portable player category, we are now listening to "In-Ear" earphones and are especially happy with some very affordable in-ears from MEElectronics. Our initial goal here is to introduce the masses to high quality music reproduction at budget prices. And what better way to save money than to buy good but affordable headphones rather than good, but expensive speakers. We are always open to reviewing headphones from different manufacturers, but we do urge you to pay Grado some attention. Grado Labs is a small audiophile company dedicated to better sound quality at affordable prices. Though not winning any awards for styling, Grado's price/performance level is unequaled!
Don't Worry Too Much About Specifications: Frequency response specifications listed on most headphone packaging are only helpful for weeding out the cheapest of headphones (under $20). True sound quality comes from the headphones producing the most accurate music reproduction, which is not necessarily from headphones capable of reproducing sounds way above and below the range of human hearing. We have personally heard headphones with a frequency response from 20-20,000 Hz with far better music reproduction quality than a pair of headphones with a 10-30,000 Hz frequency response! Impedance and sound pressure levels matter a bit more depending on what source you are using to drive the headphones. Higher end home headphones, including many Sennheisers, usually need more power to drive them, so hooking them up to a portable CD player just won't do. Grado's, Portables, and IEM's however, sound great connected to most portable players, a standard headphone jack, or a headphone amp.
Circumaural vs. Supra-aural. Circumaural headphones have earcups which totally surround the ear and can be more comfortable than supra-aural headphones which sit directly on the ear. Weight and earpad materials can vary the comfort level. Many of the Sennheiser's and AKG's we review are circumaural and very comfortable. Grado headphones are supra-aural which has been the source of some criticism for their comfort level, (it's also part of the secret behind their great sound quality). I have found however that once the headphones are broken in, they become more comfortable. Also the Grado's are light in weight, and since the headband is a sturdy leather or vinyl covered metal band, they can be bent to conform to your head (try that with the plastic cheapies).
"Open" headphones as opposed to "Closed" or "Sealed" headphones. Open headphones have grills behind the transducers that allow sound to flow in and out. Closed Cans have solid material behind the transducers to avoid sound leakage. Open headphones are often cherished by audiophiles listening at home as they can offer a more natural sound quality than closed Cans are capable of due to the confined sound. But sound leakage of open headphones, both in or out, can be a problem for many uses, (recording purposes, out in public, others in the same room, etc.). So, Closed headphones are often a necessity. Plus, if your musical tastes tend towards the bass heavy, some closed Cans may be more to your liking as some have a punchier bass than that found in many open headphones! Our favorite brand of "Open" headphones for years has been the Grado's. If you tastes are towards acoustical music, or you want to hear every little detail as naturally as possible, check out the Grado's. If your tastes are more towards bass strong music, or your needs require a closed headphone, pay close attention to the Ultrasone headphones. Ultrasone makes some great quality closed Cans that offer fuller and more detailed sound than that heard from many other closed headphone manufacturers.
Portable Headphones. I have purchased a few portable CD players and mp3 players in the last 20 years, and I am continually amazed at the marvel of such neat little machines at affordable prices. One thing that always disappoints though is the cheapie headphones or earbuds that come with such great portable players! In order to keep costs down, virtually all of the companies have shortchanged us with inexpensive headphones or buds that barely do their players justice. While we've had some customers who prefer to connect a Grado SR60i or SR80i to their portables, to be fair, the Grado's are actually mid-sized headphones. Not necessarily portable. True portable headphones are a bit smaller. Sometimes collapsible. But unlike earbuds, portable headphones can create a large, full sized headphone sound. Over the years we've been totally pleased with the Koss PortaPro, (not to be confused with the lesser quality SportaPro). We had been pleased with the Sennheiser PX100, but they replaced it with the spendier PX100-II. More recently, MEElectronics has introduced a good quality portable that has caught our ears. A couple of subcategories of portables are the "StreetStyle" headband, (behind the neck rather than on top of the head), and the "Ear Clip," (no headband, just clips to hold the transducer to the ear). Our favorite Streetstyle is the iGrado and our favorite earclip is the Koss KSC75. Here's a link to more info on Portable Headphones: Portable Headphones
Wireless headphones. Our emphasis with headphones over the years has been "sound quality". We have auditioned quite a few wireless headphones, but more often than not, sound quality wise we are usually disappointed! And reception quality.... don't get us started! Most have been bad! FYI, traditional RF,(Radio Frequency), wireless headphones that have been around for a couple of decades, can sound good at some locations, and bad at others. Depends on what radio waves, electronics, or microwaves that may be around your listening location. So what works fine for one person at their house, may not work for you at yours? Frustrating!!! And in the past there have been some IR, (Infrared), wireless headphones that transmit an anolog signal. Reception could be decent as long as you were short distance line of sight to the transmitter, but sound quality wise, IR didn't have enough bandwidth to transmit a high quality signal. In the mid 2000's we were especially impressed with the transmission quality of the xDream by FreeSystems... which used an IR signal transmitting digital information! Unfortunately the xDream is no longer available. These days, bluetooth technology has garnered momentum by headphone manufacturers mainly marketing for computer uses. Unfortunately, to an audiophile who is used to the quality of "Corded Headphones," Bluetooth is not quite there sound quality wise. And now, we are excited by the new KLEER™ wireless technology. In fact, the Sleek-Audio in-ears we recommend have a wireless option using this technology and we are impressed. And in late 2009, Sennheiser has come out with some headphones using the Kleer technology and we're very happy with them! Here's a link for more information:Wireless Headphones
Noise Reduction Headphones. Sometime in the early 90's, ANR headphones began to be marketed primarily to airplane travelers. ANR refers to “Active Noise Reduction,” (as opposed to Passive Noise Reduction which is just blocking sound with a bulky, closed headphone, or use of earplugs in the ear canal). If you’re in an environment with a steady, low droning sound, (like an airplane engine), ANR headphones can be helpful because they produce an opposite sound wave to the ear which in effect, lessens the loudness of the offending droning noise. The result, the offending noise is reduced and you now have the means to listen to music or movies through headphones at a normal volume, (FYI, turning up volume in headphones to drown outside sounds is not good for the ears). Some points about ANR headphones to remember: -- Random noises are "NOT" reduced! Talking, banging, babies crying, etc..... not reduced by the ANR circuitry. -- Sometimes erroneously called "Noise Cancellation" headphones.... they reduce one offending noise, not cancel! -- $300 ANR headphones, even from self boastful famous audio manufacturers, do not sound as good to an audiophile's ears as does a $79 Grado SR60i. Besides being closed which affects sound quality, the ANR circuitry introduces some hiss. -- If you travel a lot, by all means, spend some money on some good ANR headphones. But if you only travel occasionally, opt for the less expensive ones for traveling and buy some regular headphones for all other uses. Sennheiser makes some very high quality ANR headphones which we are liking and recommending. We are also liking one from an independent company called the PlaneQuiet headphones.-- Or, you may want to consider an IEM, as they can passively block outside noises, (see below).
IEM's, In-Ear-Monitors, In-Ear Earphones, Canal Phones... In-Ears are a tricky product to recommend. So much depends on the fit in the ear for both sound quality reasons and for noise blockage reasons. And everyone's ears are different, so what works for one person, may not work well for another! Plus, some people can't stand sticking the things deep into the ear canal, while others seem to get used to it, and love the intimacy of the sound. Etymotic and Shure kind of led the way in this category. But given the popularity of the iPod, (and other portable players), and the not-so-good earbuds that come with them, IEM's have gained in popularity and many companies are jumping in with me-too products. Even Grado now has some in-ears! Unfortunately, many of the better ones are quite expensive, ($200 and up). Besides Grado, in the $200-$400 price category, Sleek-Audio is a smaller company we have our sights on, (new products due in 2011). In the under $100 category, in the past, we were often disappointed with the sound quality as many companies really held back, (many in the lower price ranges have been lacking in detail or bass).. But now, Grado came out with one for under $100, with which we were quite pleased. NuForce came out with a very good under $50 model. MEElectronics is perhaps our new favorite in-ear brand, as they have come out with multiple in-ear's at prices ranging from $20 to $90 that rival in-ears formerly selling well above the $100 price level! Here's a link to some of the latest in-ear's: In-Ear's Due to the portability factor and the noise blocking factor, I've enjoyed some in-ears for several years now. They sound better to me than earbuds which I don't find fit my ears very well, (and sound inconsistent as a result). And I find besides being super portable, IEM's can block outside sound out quite well so I use them a lot when traveling. And a maybe not so common use... I often use them when going to sleep at night, (which rules out some of the bulkier designs that protrude from the ear). One thing I want to point out. Good IEM's can produce very clear detail. But when it comes to headphone sound, I feel a full sized headphone gives a larger sound and it's hard to compare with an IEM which produces a sound that is totally inside your head. In other words, I'm not gonna give up my Good Cans!
The truth about headphone amplifiers: Not many of you are aware that there even exists such a thing as a headphone amplifier? We get a kick out of listening to a $1000 plus headphone/headphone amp setup! But quite frankly, though the sound quality can be better than a pair of $99 Grado SR80i headphones hooked up to portable CD player.... it is in no way 10 times better! We are now reviewing and selling headphone amps, but until you are a true audiophile with a quest for the best sound possible, don't concern yourself too much. Get some good headphones first. Listen a while. And if you really get into it, then maybe step up? Whether you do want to get an amp does depend on the quality of your sound source and current amplification? For Grado listeners, Grado themselves has some very good headphone amps aimed specifically at driving Grado headphones. For years we've been very pleased with the quality of some headphone amps built by Creek. Their OBH11 is one of the more affordable headphone amps available and the build quality is stellar! More recently a tube headphone amp made in the USA by Bellari has caught our ears. If your main music source is your computer, then you should be interested in several products from NuForce which have combined headphone amps with USB DAC's. Here's a link to some more info on the above products: Headphone Amps A note on portable players: As technology has improved battery life and increased shock resistance, sound quality has suffered a bit. With many of the new players, it is getting increasingly difficult to drive a good pair of headphones. My portable CD and MP3 players do drive the Grado SR80i's OK, (though the volume control is getting nearer to it's upper end limit)! And in fact, we've had dozens of iPod owners go out of their way to tell us they love the SR80i connected up to an iPod! But eventually you might consider as an alternative for high quality playback to connect a headphone amp to the your portable. The Grado RA1 is a fairly expensive battery powered amp that we love connected up to a line-out. But you might hesitate if you're portable player doesn't have a line out, (unfortunately these days, a line-out is an uncommon feature)? BTW, it seems no mp3 players these days have a line out. But we have found there are some third party manufacturers making a line-out for some iPod models. I have been using one with my Classic iPod and have been loving listening through an external headphone amp. And FYI, there are somewhat more affordable alternatives for portable headphone amps available, but most seem to be from very independent sources and are not available through normal commercial sources. (Note: Since we wrote this, NuForce has come out with a portable headphone amp with a built in USB DAC that we have been stocking and are very please with.

The bottom line: It is possible to spend hundreds and even thousands of dollars on headphones. But we feel that some audio boutiques and even some mailorder companies try to squeeze as many dollars out of the consumer as they feel is possible by leading you to believe the more expensive items are staggeringly better. In reality, to the average listener, they are not necessarily all that much better! We often look for the price/performance level that offers close to the highest quality without going overboard on price. If you step up from department store cheapies to a medium priced pair of audiophile headphones, (under $100), such as the Grado SR60i's or SR80i's, you'll be rewarded with a huge improvement in sound quality. If your needs require a closed design, check out the Sennheiser HD280pro or the Ultrasone HFI580. If you really want close to the best sound quality available from any headphone, for around $300 the Grado SR325is and the AKG K701 are worth looking at! Once you’re hooked on the great sound quality you are hearing with your headphones and want to spend more money on music reproduction, you may then want to step up to some great top of the line headphones like the Grado RS1i or GS1000i and maybe even a headphone amp like the Bellari HA540 or a NuForce headphone amp/USB DAC!
