Onkyo ES-HF300(S) On-Ear Headphones, Silver

General Information

Take the famed Onkyo sound on the road with our ES HF300 On Ear Headphones. Passion for music is reflected in the aluminum driver housing, its shape referencing the volume control on our iconic audio components. The single arm design creates a clean, elegant profile accentuated with brushed and burnished aluminum. Soft leatherette ear pads and headband make for comfortable listening, but that's just the beginning: two 40 mm (19/16) titanium drivers, dual chambers for optimized bass, and rigid construction combine to present a wonderfully clear stereo image. These headphones handle everything from Mendelssohn to metal, with deep reaching bass and a detailed mid range testament to the long hours spent tuning the drivers to perfection. Adding further value is the audiophile grade copper cable, which provides almost perfect conductivity for superior sound quality. Protected by transparent elastomeric to insulate against touch noise, the one piece cable has gold plated connections and is the perfect length for travel. Details such as the flat folding design and detachable cable make it easier to enjoy component quality audio everywhere you go.

Pros: Aesthetics, Build Quality, Price, Balance, Subbass
Cons: Lower mids Recession, Bass Emphasis, Pad Size and Depth
This was an impulse purchase.  Not that it was hyped much (trust me, it isn’t), I just wanted to buy an on ear headphone, and these sort of showed up.  They’re relatively new so I wondered if they’d be a diamond in the rough among some pretty stiff competition (V-Moda  M80, UE6000, Martin Logan Mikros 90, ATH M50, ATH WS99, MDR -1R, and many many more).
Build Quality, Aesthetics, Comfort, Gripes:
First off I’d rate the build quality as very good.   I don’t see any structural flaws.  The cup themselves I believe are aluminum, and the core of the headband is also a really strong metal.  There is some plastic in the construction, but don’t expect that Beats type plastic or that MDR 1r type plastic.  It’s is much much much more sturdy, and it yields no structural weaknesses.  It also helps lessen the weight of these.  Also, the plastic is rubberized, meaning it has a thin layer of rubber as an exoskeleton, giving it a more high quality feel. I’ve tested the build quality by stretching the headband beyond its elastic limit and they didn’t break (the headband was basically a straight line at that point).  In addition, factoring in the price ($170 USD) you’ve got a fantastically built headphone.
These headphones look stylish, and even more stylish around the neck.  I’ve gotten a lot of compliments if that helps.  The stealth black works well, but I could do with a little more contrast.  The cable really is the only source of contrast in color.
The comfort is about average.  They are more comfortable than the average on ear, but a little less comfortable than it’s over ear competitors.  The pads are larger than the Momentums (basically an on ear), but a tiny bit smaller than the WS99.  They aren’t uncomfortable for me, but I can see some people experiencing discomfort.  The pads aren’t the softest (not memory foam), but to be honest that isn’t much of an issue.
The cable doesn’t have an IOS controller.  This means absolutely nothing to be, but be warned.  Also, the cables are detachable, but it’s really hard to pull the cables out of the ear cups.  I also experience a slight channel imbalance favoring the right ear slightly, but this isn’t a problem since you can easily adjust the channel balance on just about any device.  One more gripe: a good seal is easy to maintain (you can talk and do all the backflips you want once the pads adjust to your head), but can take a few seconds to achieve.  Good thing is I have worn these in literally 4 degree weather (and while it was snowing like crazy) and maintaining a seal isn’t difficult.  I have an average sized head with ears that stick out slightly more than average and I experience no problems.  You may experience problems at first but they will most likely go away after good use.
First let me describe the sound signature, starting from the left of the frequency graph: the bass.  The bass extends quite low with great weight and authority.  Yes the bass is emphasized, but definitely not to bass head levels.  They have a tiny bit more low bass impact than the Momentum, and a bit less than the ATH WS99.  Anyway, the sub bass extension really is something that makes these headphones stand out.  You’ll hear sub bass notes you haven’t heard before if you listen to cans like the Momentum or MDR 1R.  Now my only problem with the bass is that it’s a bit above neutral, and I prefer a flatter response since I don’t really listen to much bass heavy music.
That being said, I’m not sure I’d call these warm sounding headphones.  I associate warmth less with simply bass than with mids to lower mids presence, accompanied with a mid to upper bass boost.  These sound more dynamic, more exciting then something like the Momentum, MDR 1R, UE6000, ATH WS99, or ATH ESW9a that sounds warm and laid back.  Moreover, I can sense a dip in the lower mids, but just a small one.  It removes a little bit of the warmth from the vocals and replaces it with a more airy, more spacious vocal presence.  As a result, compared to mid centric headphones like the MDR 1R, ATH WS99 (kind of mid centric), and Martin Logan Mikros 90, the vocals can sound only a tiny bit hollow.  The dip isn’t huge, but it’s noticeable.
Ah the treble.  This is something I like about these.  The treble is not offensive, neither is it conservative.  It isn’t crazy detailed like the Mikros 90 (*******!), but it has presence, lending to a fantastic balance, and beautiful female vocals.As for the soundstage, I’d rate it at slightly above average.  It’s a small step behind the class leading M500, or MDR 1R, but a step above the Momentum.
To sum up:  I haven’t liked a headphone like I’ve liked this one in a very long time.  For instance: I like the M500.  It’s got good sound, an awkward but interesting soundstage, and awkward fit (clamp is too light), and only OK isolation.  They are also a little creaky, at least for me.  I like the Momentum, but I can’t get a good seal, the sound is only OK, and they cost a little too much.  The B&W P7 is something I really liked both sound wise and looks wise, but there was nothing that stood out about it, especially at a price of $400.  I’m really liking the Martin Logan Mikros 90 right now, but I haven’t had them for long enough.  These headphones don’t really do anything wrong in any compartment, whether its build, aesthetics, sound, or comfort, and they actually do some /things that make them stand out, like for instance it’s sub bass, or its female vocals.  Look, I’m not saying these aren’t without their flaws, all I’m saying is I haven’t found them yet.
Used: Sansa Clip Zip, my Home Reciever, Shiitt MAgni, iPod Tough 4g, iPad 2, Samsung Galaxy Player 5, Fiio E6.

I'm in Japan and I heard these 2 days ago. Was looking for Bass cans and bought the 57mm JVC's but I will go back and buy these for more general listening. They are OUTSTANDING cans....WHY......WHY WHY  WHY are these not being raved about when other lesser cans are?? I had zero knowledge of these until 2 days ago.
Great low end and overall sound
These really are phenomenal! Punch WAY WAY above their weight. I agree with Hawaiibadboy. I just cannot fathom why these are not getting more raves. The bass is a tiiiny bit boosted and looser than orthos, but the treble and detail is spot-on.

Pros: Sound quality, good isolation, great modern looks, sturdy build quality, good value performance
Cons: Ergonomic niggles, uncomfortable for me
Onkyo's entry into the headphone game
After selling my V-Moda M80s due to discomfort and trading my Shure se215s due to finding ergonomic issues with IEMs in general, my search for a portable headphone continued. As a subscriber to Innerfidelity, I opened youtube one day to see Tyll's new review of the ES-FC300 and ES-HF300 headphones from Onkyo. Portables! I knew Tyll typically only reviews things he likes, so I gave it a watch. He sure seemed impressed with them! And they looked like they were much closer to circumaural headphones, maybe they'd be much more comfortable for me than the past on ears I've tried? I bought the HF version that day and waited for delivery. Here is what I found.
Aesthetics and Build Quality

These Onkyos really are gorgeous, from the packaging to the finish, really beautiful. I of course opted for the HF version due to aesthetics alone, any supposed performance improvement would simply be a bonus. The ES-HF300 comes is all black, a combination of pleather, rubberised plastic and brushed aluminium. I'm a big fan of this. I've always been a sucker for brushed alu, and I love that the plastic is rubberised for pleasing the user's fingers and eyes. I would say however that the pleather is slightly disappointing. It's by no means what I'd call bad quality pleather, but I've certainly had nicer, and at this price point I think it could be better. It's soft (which is the most important thing), but it has a noticeably more plastic feel to it than others, and the texture seems quite fake. V-Moda's pleather on the M80 and Denon's pleather on my D2000's are both softer and more convincing of being leather. Still, it's a hell of a lot better than the Ultrasone rubbish. 
Another small disappointment is the chrome finish on the cable. I was disappointed to discover that the chrome on the jack and plugs are indeed plastic, rather than metal. There's something about chrome plastic that seems super cheap to me, cheaper even than the lower priced FC version's cable that is coloured red (on the black version). I am nitpicking, though. The HF300 definitely feels and looks like a premium headphone of it's price range, niggles aside. Especially with the HF cable, which with it's transparent, silver finish looks really appealing.
Build quality is very solid, nipping at the heels of V-Moda, I daresay. Aluminium brings strength to the key areas that need it, such as the cups and the joint connection to the headband, as well as the core of the headband. Many people consider plastic a bit of a dirty word when it comes to build quality, but this headphone demonstates plastic done right. It's a great weight saver, but it's also thick and solid. I have no reservations about predicting a very good durability reputation for this headphone. The cable, whilst being somewhat thin (not overly so, about what you'd want for a portable), is quite pliable but seems strong. I don't have any complaints about the build. 
Sound quality
The most important aspect of any headphone, and to quote Tyl on this; "Boy, this headphones deliver!". They really do.
The bass is quite warm, approaching basshead levels but not quite. It's tight, solid, impactful and articulate, with good extension. Punch is very satisfying with a pleasing decay. The Onkyo's bass is in downright good taste in comparison to a lot of it's more mainstream competitors. Average consumers would benefit to becoming accustomed to a bass response like this. The mid range is similarly strong, retaining great presence with vocals of both the male and female variety. I love a bass to mid-range balance like this, it's great that there are now affordable headphone around where you don't have to choose between bass or mids. The ES-HF300 give you both. The treble is also well behaved, too. It's the least forward section of the sound to my ears, but not what I'd call rolled off to the point of being detrimental. It's never harsh but allows those high end details to come through well. 
With that said, I do feel that this is the area where the performance really reminds you that you're using a medium sized, sealed portable. The treble seems to highlight the more closed in soundstage, which is really part of the natural limitation of the headphone design. Make no mistake, for what it is, it's more spacious that you might expect. Just don't expect the imagine performance to rival full sized headphones, especially those of the open variety. Everything taken into consideration, I'd say it outperforms the V-Moda M80. It's a nice little step up from it, and at the same price, it's more than welcome that it can best an already awesome sounding competitor. I'd describe the presentation as very similar, just with the nuts and bolts tightened up a bit. 
Ergonomics and Comfort
Unfortunately, just like the M80, this is the area that lets the headphone down for me. 
Starting with ergonomics, I mentioned that the bass levels were warm but approaching basshead levels. This is true, however that is how they sound when you can achieve an optimal seal. Achieving this is honestly going to be somewhat impossible for some people with ears that stick out too much.. It's really down to ear shape and size, so buying blind is going to have a bit of luck involved. I have average sized ears, and I can achieve a proper seal without much difficulty. However, it's not the type of headphone that you can get a good seal (and appropriate performance) no matter how you wear it.
In terms of size I would say they're about as large as I personally think 'portable' headphones can go. I can wear them around my neck without them getting in the way too much, but only just. Much bigger and they'd be too intrusive to my chin. They isolate well, too, which is a nice bonus. One other niggle for me is that the cables are actually very awkward to remove from the earcups. They need a good hard yank to get them out, but the area you have to pull on the cable is quite small and provides little grip. I also don't find that a dual entry cable is really the best for portable application, a single sided cable is better for being out and about, in my opinion.
As for comfort, this is the real issue of the headphone for me. Whilst I do think it's outright more comfortable than the M80, it's still well under what I consider to be truly comfortable. Anything over an hour of use and I really need to take them off, which quite frankly just isn't good enough for me. I'm constantly distracted by the comfort, fiddling with them and readjusting them in a vain attempt to make them comfortable. It's quite unfortunate. The PX100 is still the only on ear headphone I've found comfortable, whilst all these more expensive on ears have failed miserably. Frustrating, indeed. Luckily comfort is subjective, so I'm sure many other users will have a good experience. It's just not that way for me.
As for my search for my portable headphone, I've honestly grown frustrated with the entire thing. It seems every portable solution seems to have some kind of enormous flaw that ruins it. This made me look back fondly to the Sennheiser PX100, which I was so very happy with. Sure, it didn't look as nice as the others, didn't really isolate at all and it was technically inferior. However, it had a very pleasurable sound signature and performance level for the (little) money, it was highly portable and built well, and was very comfortable! I think I've realised I need to take things back to basics. I experienced more listening satisfaction due to the package as a whole with the PX100 than any of these more expensive portable solutions. I've decided my next stop in portable audio will be the PX100ii. A PX100 with improved looks, build, ergonomics and sound? Count me in. Unfortunately, the ES-HF300 has been an almost identical (but fast-tracked) experience to the M80 for me. Comfort ruined it, and it's unfortunately got to go. A shame. I'll the say the same thing as I did about the M80. It's hard for me to have to get rid of it because I love the sound, looks and build. If you find this headphone comfortable, then I'm truly jealous. 
I really have no reason to believe I'd find any of those comfortable. I haven't heard much about the on ear momentums, but the HD25s and DT1350s do not at all have good reputations for comfort. 
What separates the PX100 from those other on ears is that they're way lighter, have less clamp force, and are small enough that I can avoid having to have them sit on the top half of my ear at all. That's why they're comfortable.
Yeah...I own the older version of the 1350 and have no issues with their comfort...supposedly the pads on the new 1350s improve the comfort but probably not to the level you need.
That said, the HD238s really are comfortable and don't clamp like the M80s or DT1350s...looks like their sound signature is pretty close to the PX100s as well on paper.
One other thought, the Phiaton 320s...even more comfortable than the HD238s...fairly neutral sound though.  I own these and every time I pull them out, I end up listening for multiple hours with them...'list' for $199 currently $82 on Amazon.
I own a pair of these, with the cheaper cord. I have no issue with comfort and I have a huge head and can wear them for hours. I find them sounding amazingly close to my Sony MDR-1R.
