    • Excellent sound. Excellent sound isolation--for those with medium to small ear canals. READ UPDATE AT THE BOTTOM
These earphones replace a pair of Etymotic Research ER5 earphones I used for nine years before one earphone quit. The price of those ER5 earphones was comparable to what I paid for these HF5 earphones. Because my old Etymotic Research earphones performed so well, I had high expectations of these HF5 earphones. I’m not disappointed. I find the HF5 sound isolation and audio quality are excellent. I don't miss the ER5s at all. I consider sound isolation to be essential to audio quality. To my mind, if you have other noise bleeding in, it doesn’t much matter how good your earphones are. I spent a lot of time researching earphones when I bought my first pair of Etymotic Research earphones. Those rated high on audio quality and no one else could claim the sound isolation they had. They delivered on the promise. When it was time to buy new earphones, I did the same research and got the same result: no one else makes earphones with both excellent audio and excellent sound isolation. With all noise shut out, these HF5s make me feel as though I’m in the studio with the band. Every rustle and breath comes through. You hear the guitarist’s shirt brush against his guitar. I point this out not as examples of distraction from the music but to show how completely these earphones deliver every bit of sound in a recording. If the artist didn’t want those sounds in the recording, the engineer would have removed them. When I listen on these earphones, I hear everything. The HF5 earphones also create a huge sonic space. You feel as though you’re in a vast empty room with just you and the music. They place each instrument separately in that space--when the music is produced that way. It’s complicated, and I don’t understand how it works, but some producers pull all the sound together into one stream, others maintain or create separation between the instruments and voices. Any pretty-good earphones with good fidelity in bass, midrange, and high end will do for music that’s pushed together into a wall of sound, as much pop music is. But many indie, folk, blues, jazz, classical, and other specialized recordings often use this separation in space to bring you into the middle of the sound. You feel as though you are there, with the music spread around you, just as it would be if you were right there during the performance. The intimacy of this experience has an almost emotional quality. These earphones deliver that experience. Etymotic Research promises more than 40 dB of noise reduction. That’s a lot. By comparison, the best foam earplugs, when inserted deeply into your ears, reduce noise by 32 dB. That’s plenty to save your hearing, but not as good as these earphones. I use foam earplugs often. The company’s claim is true: these earphones keep out more noise than the best foam earplugs I can find. I’m an artist working with steel. I use power tools in a small, concrete-walled studio. The noise is truly deafening. It’s loud enough to be annoying even with foam earplugs. However, I put in my Etymotic Research earphones and listen to acoustic music at medium to low volume while I use a power grinder on steel . Another example: When I use the lawnmower (a quieter machine than the power tools I use), I barely notice the mower. Time will tell whether these new earphones are as durable as the last ones, but I expect they’ll do as well or better. The old ones had ordinary wires, but these have Kevlar reinforced wires. These HF5 wires are also springy so they don’t tangle easily. The earphones themselves are made of metal and stick out of your ear a little so they’re pretty easy to remove. Because of the seal necessary to keep out noise, Etymotic Research earphones are a little difficult to pull out. The long body of the HF5s helps with that by giving you something to grip. Not very many things I’ve bought over the years have given me as much satisfaction as my Etymotic Research earphones. If sound quality matters to you and you listen to music anywhere but in your living room, I highly recommend these HF5 earphones. UPDATE--CAUTION IF YOU HAVE WIDE EAR CANALS Fit on these earphones is not as good as with the earlier ones. None of the silicone tips fit snugly for more than a few minutes. For me, noise isolation isn't much better than non-sealing earbuds. The memory foam tips work well, but only two or three times per pair, then they are squished and not strong enough to maintain a seal. Noise isolation is crucial and an important reason I bought these to replace earlier ER earphones. THE PROBLEM IS PARTICULAR TO SIZE, NOT A GENERAL ISSUE WITH THE EARPHONES. I'm average height and weight, but apparently my ear canals are large: consider the size of yours when buying. I now need to buy custom tips which will nearly double the cost. I'm in my fifties and have lost a little high-frequency hearing, so I can't comment authoritatively on the sound, which means I can't confirm the value for cost, now that I have to get after-market tips. ER is a reliable brand and I still recommend their products. However, sound isolation now depends on the size of your ear canals. If you have large ones, you may want to look elsewhere, I'm afraid. ... show more

    • Well made and very clear sound, but insufficient bass at low volumes
I really, really wanted to love these earphones, but regrettably, I am returning them. I like to listen to music all day while working, and my new eyeglasses have thick temples which end up giving me a headache from pressing the glasses into the sides of my head, even with "gentle" headphones. (I am alternating between AKG K240 Studio's and Grado SR60's for wired use, and LG Tone+ HBS-730 for wireless/Bluetooth use.) I read all the great reviews on these HF5s and decided to give them a try because I wanted a comfy pair of wired headphones. They look really great, and I was pleased to see that they come with FOUR different options for installation: standard triple flange rubber (the ones that are already on them when you receive them), large triple flange rubber (for people with a larger ear canal opening like myself), cylindrical memory foam (which also work very well for me, and would probably fit a lot of people since they are quite compressible), and half-round squishy/tacky rubber (which also fit me well.) The standard flanges were too small for my ear, since they inserted easily all the way in with no resistance, and didn't block the ambient sound from the room at all. All of the other three had incredible isolation, almost completely blocking out all ambient sound, and all three were also extremely comfortable. I could easily wear any of them all day long without any discomfort. So why return them? I was expecting a relatively "flat" full spectrum response, and these phones accentuated the mids and highs too much for my taste, with much too little bass until I turned the volume up considerably. They are extremely sensitive - I was still able to clearly hear the music with Windows Media Player on 100 and my PC hardware volume setting on ZERO. I wanted to listen at a volume setting of 5 or 6 (out of 50), which is loud enough to hear the music comfortably while drowning out all normal ambient noise, but not quite loud enough to prevent hearing a bomb or fire alarm going off. But at this moderate volume, the bass was almost non-existent. Turning the volume up to 15 or 20 makes a good improvement in the bass, and once I turned it up to 30 or so, it sounded really, really fantastic. But that is starting to approach the point of being loud enough to cause ringing or long term hearing loss, which I definitely don't want. I initially thought that maybe the issue was just the crappy DAC in my PC, so I plugged them directly into my Oppo BD-105 and listened to some good quality CD's. The Oppo has one of the best DACs available. No change - still no bass. Next I tested listening to a the same portion of the same CD on the HF5s, the AKGs and the Grados, and it was definitely clear that the HF5s were lacking a lot of bass at low volumes. I realize other reviewers have said that this probably means the phones are simply not inserted fully. In order to try to confirm that this was not the case, I did another round of testing with all four earpiece types, inserting each of them as far as they would go using the proper insertion technique. (For example, to insert into the left ear, reach around behind your head with your right hand and pull upward and rearward on the top of your ear, then insert the plug with the left hand.) There was nothing I could do to get the bass to sound anywhere close to what it was with the AKGs or the Grados. Like I said, I really wanted to love these, and I was so excited to get them. But since they needed a higher volume level in order to start sounding good, I chose to return them. I did test them with the volume all the way up to 50 (the full max) on the PC, and tested with the volume up to 100 on the Oppo player. In both cases, the sound remain clear, crisp, clean, and EXTREMELY GOOD, with no noticeable distortion or overdrive. In this sense, the HF5s even exceeded any reasonable expectations for earphones, and for someone who really likes to listen to their music LOUD, I think you would be extremely pleased and impressed with these. I did notice there were a lot of negative reviews centered around durability. I was mildly concerned about that before ordering, but bought them anyway because of the manufacturer's two year warranty. I had planned to keep my receipt, and figured that even if they died after 2 years and a day, it would be worth it to have great sound for $65 per year. Well, after seeing them, I have to think that the people who had durability issues simply must have been abusing or mishandling them. I found them to be extremely sturdily constructed, and I am sure that if I had kept them, they would have lasted many years, as long as I remembered to unplug them every time before standing up and walking away. The cord length is fine for use with the PC, but was barely long enough when sitting on my easy chair next to the home stereo, so I was planning to buy a coiled extension cord for use with the stereo as an added insurance policy. (Something like this one: http://www.amazon.com/kenable-COILED-6-35mm-Stereo-Extension/dp/B0098B1T34/ref=pd_sim_sbs_e_5?ie=UTF8&refRID=10VJWTVXD7N7F2G5PEJ7 ) Bonus tip: I have seen lots of people out on the street and in restaurants and offices "twirling" their headphone cables, mindlessly spinning them around their index finger as a nervous habit. This always amazes me - they seem oblivious to the fact that there are hair-thin copper wires inside those cables, and the laws of physics DO apply - metal will eventually fatigue and fracture if you keep bending it hundreds of times. So folks, treat your earpieces with due care, and they should last a long time! Background info: I am a former professional musician, have worked as a sound engineer (operating the mixing board at live concerts and assisting the engineer in a recording studio), and so I am perhaps more "fussy" about good quality sound than most people might be. Lastly: I should point out that for wireless listening with Bluetooth-capable devices, the LG Tone+ HBS-730 is really hard to beat. I have not personally heard anything better yet. Complete full spectrum audio with tons of bass, and it's even a cell phone headset with a mic. I won't devolve into a review of the HBS-730 here, but I'll just say that it is a bit temperamental in maintaining its connection to the cellphone. The mic audio often drops out for no reason, which is super annoying. But for listening to music from the PC or cellphone, the audio is great, and if you don't need something with a wire to plug in, that's the one I'd recommend. ... show more
