From the Manufacturer
Etymotic Research HF5--High Clarity, Great Fit, and Maximum Noise IsolationMade by Etymotic Research, the people who created in-ear earphones, the HF5 delivers Etymotic's world-renowned sound quality in a pair of comfortable, convenient earphones. The HF5 provides a near-perfect music experience.
The HF5 works with all MP3 players and iPod models, as well as the iPhone and any other device that operates with a 3.5 mm stereo plug. The HF5 can be worn with the cables in front or in back of the head, and the cable slider can be adjusted by moving it up or down for a snug fit.
The HF5 comes in black, Ruby, and Cobalt to match your style
Amazing response accuracy means unmatched crystal-clear sound
Designing the HF5: Etymotic Research Focuses on Noise Isolation and Response AccuracyKeeping Things Quiet with 35+ dB Noise Isolation
The special 3-flanged earpieces that come with the HF5 provide 35 dB noise isolation or more (depending on the eartip used), making it one of the highest-rated products on the market for both active and passive noise-canceling headphones. With 35 dB of isolation, you won't need to turn the music up as loud to hear every nuance of your favorite artists, saving your hearing and preventing "ear fatigue". Once you obtain a proper seal in the ear, watch the world disappear, leaving you with your favorite music reproduced with remarkable clarity.
How Etymotic Research Measures Response Accuracy
The accuracy score is perhaps the single most important tool for earphone design. A perfect recording of a live performance played through earphones with 100% accuracy would produce the same sound at the eardrum as the live performance. A complicating factor is that the acoustic resonance and horn effects of the ear change a flat signal entering the open ear to an eardrum signal with the approximate frequency characteristic of the target curve. A perfect earphone will create that same frequency characteristic at the eardrum.
Hitting the "Target Curve"
Target curves on Etymotic Research graphs indicate 100% accuracy: The open ear diffuse-field response of the KEMAR® mannequin modified to compensate for the high frequency boost added to high-quality recordings. This modification (approximately 5 dB at 10 kHz) is necessary to avoid earphones sounding too bright on commercial recordings. Commercial recordings have a high-frequency boost that compensates for the high frequency roll-off in studio monitor loudspeakers and high-quality stereo loudspeakers and earphones.
Earphone response is measured on a KEMAR® manikin that has the same acoustic properties as the average head and ear. 25-band accuracy scores are calculated by summing the difference between the earphone response and the target response in each 1.3 -octave band from 50 Hz to 12.5 kHz.
In the 1970s, Consumers Union used an "Accuracy Score" to rate loudspeakers. Consumer Reports reported that it was possible to predict listeners' loudspeaker ratings within 8% from a calculation based on one-third-octave frequency response measurements converted to loudness in sones. The average error in loudness from a perfect system, subtracted from 100%, gives the accuracy score. Etymotic Research extended this 21-band calculation to a 25-band calculation and routinely uses the 25-band accuracy score in all earphone designs.
Other in-the-ear earphone manufacturers do not report accuracy scores, but Etymotic Research has tested all competitive products. The accuracy scores of Etymotic Research earphones are higher than those of most loudspeakers, and well above all competitive earphones, except electrostatic headphones that cost thousands of dollars.
What Critics Are Saying
"They're cool looking (with the right tips, they look like sci-fi laser pistols), have little to no cable movement noise and reproduce sound in a way that is both perfectly clear and highly enjoyable. Everything about these gives the impression of quality, from the brushed aluminum finish to the way that music suddenly sounds distinctly layered in a way that it didn't before, and that it doesn't on many similarly priced units. [...] The tighter seal that these offer to most people is conducive to better listening, and the isolation properties are superb. You can't hear anything else with these guys in. Every manufacturer should have something like this." --John Herman, Gizmodo.com

The ER-4 delivered like no other earphones, with not only the sound quality, but the noise reduction. As someone once said "It's the closest thing there is to injecting the music right into your brain." I completely agree. It took some getting used to 'listening' to the bass as opposed to feeling it, but now these are irreplaceable.
I have bought several pair of the ER-4's due to damage, losing them, etc. And it was time to replace my current pair. I decided to get Etymotics newest model, the HF5. I didn't expect a huge improvement over the ER-4's, but I was wrong.
At first I felt like the earphones didn't fit as well as the ER-4's. But then I realized that these actually go DEEPER into your ears than the ER-4's. And once I got them in there... WOW! The sound was actually so much bigger and brighter than the ER-4's. The ER-4's were great, but the HF5's is like watching High Definition Television compared to regular TV. The highs are brighter and the bass is bigger.
The only thing I wasn't happy with, at first, is the cord. They seem to have switched back to the more grabby rubbery style cord as opposed to the smoother plastic. While the rubbery feels nicer, I was worried it would grab onto my clothes too much. That hasn't been a problem so far.
They could have also included a few extra filters.Read more ›
I bought these headphones thinking that I would now have the best of both worlds: the sound of the ER-4Ps with a better design. I was wrong. The design of the Hf5 headphone itself is better than the ER-4P, but the sound of the Hf5 does not match the ER-4P. To my ears, the ER-4P and Hf5 are very similar at the low end (neither is particularly strong in bass). However, at the mid-range and especially the high end, the ER-4Ps have more detail and clarity between different instruments and vocals. The Hf5 tends to sound more muddy IN COMPARISON to the ER-4Ps and the high end of the Hf5 has more roll off than the ER-4Ps (i.e., the highs on the Hf5 won't go as high as they do on the ER-4P). Vocals and mid-range on the ER-4P sound so much better than the Hf5 that I wonder whether I had a bad set of Hf5s.
Looking at Amazon's prices, the ER-4Ps are only $20 more than the Hf5. If you are spending that much money on headphones, the ER-4Ps are a better deal.
This is not to say that the Hf5s are a bad set of headphones. To the contrary, I found them to compare very favorably to the Q-Jays. The Q-Jays had better low end (bass) than the Hf5, but the Hf5 was better than the Q-Jays on the high end and the Hf5 seemed to have a better soundstage (more clarity and detail). The Q-Jays are smaller and fit better than the Hf5; HF5 are slightly better than the Q-Jays at blocking external noises.Read more ›
They are not perfect, and, for instance, I would say that the overall sound quality and comfort (in a quiet environment) is still better with my Sennheiser 595's, but they are definitely the best in-ear headphones I have tried by a landslide. Some care is required for proper insertion into your ears. They have a helpful video on their website showing how to properly insert the various included tips into your ears to ensure a proper seal--which, if you don't have a proper seal, you will be disappointed because the noise isolation will be severely diminished and the bass response drops considerably.Read more ›
