Product Description

Product Description

The hf3 is the next generation of the multi-award-winning hf2 headset.

Selecting an Eartip
The eartip that is most comfortable is the likely choice, but it MUST SEAL well in your ear. If you can easily hear others when the volume is off, you don’t have a good seal. Twist it in deeper, or choose another eartip.

When changing eartips make sure the eartip fits securely on the stem of the earphone.

Proper Insertion
Important: Sound quality, full bass response and noise isolation all depend on a good eartip seal in the ear canal. View Earphone Insertion Video

  • Carefully insert the earphone while pulling up and out on the back of the ear.
  • Twist the earphone up into the ear canal while inserting, until outside noise is blocked out.
  • 3-flange eartip: Moistening eases insertion.
  • Foam eartip: Roll down or compress foam eartip before inserting. Hold the eartip in place for about 5 seconds while the foam expands to create a tight seal in the ear canal.
  • Glider eartip: Simply push into ear canal.

They work great at blocking outside noise and sound great too.
Akskydiver
Consequently, I've tried several different in-ear headphones over the past few years - Shure, Etymotic, Klipsch, and the HF3 are the best I've ever heard.

I again contacted Etymotic asking them for assistance ....ZERO response!

I am admittedly a johnny come lately to the iPhone/iPod music movement, one of those oldies who refused to use my iPhone as a music device until just a short while ago, skeptical that real sound could come out of this little thing. Having recently tried listening with the cheapo earphones that came with my iPhone - and being somewhat surprised by the reasonable fidelity I could get with them -- I decided to step up to the very well-reviewed and regarded Etymotics, despite a number of naysayers who complain about the lack of a low end. I cannot say I am unreservedly thrilled with these phones, but having given them some time to warm up - and for me to warm up to them - I have to say they do provide impressive clarity and accuracy, albeit in a cool, glossy sort of way.

I listen mostly to jazz and classical music, with a smattering of rock/pop, and I loathe the boomy muddy bass that comes out of a lot of speakers, subwoofers and even headphones these days. So I'm definitely not looking for exaggerated, thumping bass. However, I definitely am looking for sound with warmth, presence and body. I found the Etymotics phones to be accurate -- perhaps to a fault. The problem is they come up somewhat short in the warmth and body department; although as noted below, you should give them some time to break in before passing judgment on them, because they will richen up some with use, and you may warm up to their sound as well. I also urge you to get a pair of quality foam tips for these phones - for comfort and sound quality, in my book they can't be beat.

Yes, the HF3 seems to deliver sound that is relatively uncolored and 'flat.

I have used Etymotic products for years and I have always rated them 5 stars. I have 2 HF-3 Both in warranty. I recently purchased an iPhone 4s and the microphone amplifies the ambient sound to great distraction. I called Etymotic customer service and they stated that they are aware of the problem and they don't have a solution. Basically told me I had to live with the problem or by someone else's product

This product did not work well with my iPhone. I could not use it to make calls because the recipients all heard an echo when I did (I used my cheap head set and the echo went away). I also could not use these when I was active, like at the gym, doing yard work, etc. because they kept turning on my iPhone "Voice Control". They only block out noise a little better than my other head sets and the sound is only moderately better. This is one of the worst products I have every purchased and I am surprised anyone likes them.

I have have owned 3 different Etymotic headsets and this unit sounds great but is very
fragile.
I lost sound in one of the earphones 1 month after receiving it.
Filed claim with Etymotic and they sent RA and after receiving the unit I shipped they quickly sent a replacement headset.
3 months later I had the same issue with the replacement headset.
I again contacted Etymotic asking them for assistance ....ZERO response!
I waited a week and again filed a claim and again ZERO response.
I can accept Etymotic not replacing the second headset.
But to not respond to a customers request for assistance is not acceptable.
After all the have competition....

These earphones are exactly what they claim to be, accurate and noise isolating.

As reference, I am also a recording musician. I play guitar, bass, piano, and sing. I have recorded and mixed a professional studio album with my band. I also have a home studio and have owned several studio monitors. For those who don't know what studio monitors are, these are "speakers" that give you the clearest, cleanest, most accurate response of your recording. And this exactly what I was looking for when looking for headphones, and I found on these earphones.

At first I was scared that there was no bass response, like many have said, but then I checked their website on the proper way to fit the earphone, and voila! - I had perfect bass response and all frequencies at a flat level, with the needed spacing among each of the frequencies. As others have said, I can hear instruments that I had not yet heard in songs as well as cleaner definition on instruments that I knew existed.

As a recording musician, I strongly recommend these headphones to anyone who is looking for a clear reference earphone.

Before buying this I tried to read if it supports iPhone5 and I did not find any useful info. I took the risk and bought it only to realize that I made a wrong decision. Either the piece sent to me is defect or this model just doesn't support iPhone5. When I connect it to iPhone5 the phone just works as if nothing is connected to it. I can't hear voice from the headset and the mic is not on.
To my surprise after 3 minutes, the headphones started working but the microphone was very sporadic.
One of few bad experiences on amazon!

I have been buying etymotic noise isolating earbuds for years. They are amazing. I can walk around NYC and because my ears are plugged up, I can still hear my music even as a bus or train roars by. Before using etymotics I would have the volume on my iPod/iPhone somewhere around 75%. With these I have the volume around 25%. Because all the background noise is blocked out, you can have the volume that much lower and still hear your music. The high price of these earbuds is well worth the fact that I am saving my hearing. What price can I put on not going deaf? This particular model is great because it has on-wire controls for iPhone, which work great.

The one problem with all etyomic earbuds I have ever had is that the cord is not durable. I've had ER-6i, hf2, and now hf3. For the price these things cost, the ER-6i should still be working. To etyomotics credit, their warranty service is amazing, and they have given me many replacements even after the warranty expired. That being said, the cords should not wear out and break in the first place. Use a really strong and durable cord! You have the technology to make earbuds that are this amazing, but you can't go the extra mile to make a sturdy wire? It's usually the area around the jack that wears out. I'm thinking of getting a very small extension cord. That way the extension cord will wear out, but it can be replaced.
