The Delightful Onkyo ES-FC300 and ES-HF300 Measurements

Raw frequency response (lower gray traces) shows some variation in low frequency response with positional changes, likely due to difficulty sealing on the measurement head ears as these are not quite full-size, over-ear cans and will have some difficulties in this regard. My feeling after wearing these cans is that this will not be as big a problem as might be represented here. (The dummy's ears are a bit stiffer than human ears and makes sealing a bit more difficult with on-ear style headphones.)

Compensated frequency response plot (upper blue and red traces) show a well extended bass response with an overall warm tilt from 30Hz to 3kHz of about 15dB. Recent developments at Harman research regarding proper target curves for headphones seem to favor this kind of response, albeit with not quite as strong a warm tilt. The little dip at 250Hz does not align with the primary driver resonance hump in the impedance response centered around 50Hz, and seems to me likely caused by ear-pad resonance. Response above 3kHz is a bit herky-jerky, but this is quite normal. While there's a bump at 10kHz it's not the sometimes seen strong peak, which is a very good thing. Treble response above 10kHz does not drop off severely and make for the well balanced treble heard in listening tests. I found these cans pleasantly, but not excessively warm and fairly neutral otherwise. If this curve had 10-15dB less overall warm tilt it might be considered very near ideal.

Impedance plot shows some variation, but it's nice and clean without any fine-grained bumpiness between 1kHz and 5kHz indicating good acoustical engineering in and directly around the driver and diaphragm.

30Hz square wave shows a very typical shape for a warm, punchy sounding headphone. A nice linear wave top after the initial shoulder is a good indication of tight bass response, as is the complete lack of increasing distortion in the lows of the 90dBspl THD+Noise plot.

Lack of a strong overshoot on the initial rising edge of the 300Hz square wave bodes well for a treble response without harshness, but subsequent significant second and third peak, coupled with a somewhat noisy response thereafter might have contributed to the slightly artificial and hazy treble response heard in listening. This can also be seen in the impulse response plot.

THD+Noise response of the 90dBspl traces (blue and red) is a bit high, but not unusual at all for a small, sealed headphone. The 100dBspl traces (yellow and green) are nicely below the 90dBspl plot at all but the lowest frequencies indicate a headphone with very good power handling capabilities. This headphone will remain clean at loud levels.

Isolation plot show a headphone that will do a very good job of keeping outside noise at bay. Broadband attenuation is very good at -16dB.

With a 32 Ohm impedance and 0.032Vrms needed to drive these cans to 90dBspl, these will easily be driven to solid listening levels by portable players and smartphones.

This is an excellent set of measurements for a headphone of this type and price. Onkyo seems to have been well aware of the nuances of headphone design and have done an excellent job with these cans. Big thumbs-up from me!

Nice review Tyll. I have a soft spot for Onkyo gear so it's nice to see that they've entered the headphone market with a typically attractive, well built product that performs exceptionally well for the price.

...I had so little hope at first seeing these cans, but they sure did pull it off. I'm pretty excited about that, having another "power player" in the headphone world is pretty cool.

Hey, what are your opinions on these headphones vs the m50s?

I understand they are around the same price point, even if they are not in the same category.

Tyll Hertsens's picture

I tested them head-to-head as well (sorry I forgot to mention it in the article), I found the Onkyo had a smoother treble. The M50s have always seemed a bit harsh to me. The Onkyo seems quite a bit better in most regards.

The new budget king? Dunno, but it's close to it.

donunus's picture

Are the m50s the newer ones? I hated the old m50s yet I love the newer M50LE silver model. Slightly bright but I found the highs very smooth even though it is balanced towards the bright side.

Tyll Hertsens's picture

....I'm pretty sure.

How is the isolation relative to other portable sealed on ears? is it as isolating as the hd25s? vmoda m80s? noontec zoros? 

 

or were they similar to over ears? if so is it enough for heavy duty train/subway commuters?

MarcoGV's picture

Tom22, the measurement downloads answer sheets on this site answer your question to some extent.  The Onkyo's broadband isolation of -16db is equal to that of the hd25 (at least for some of the measured items) and of the Philips Cityscape Downtown.  It is better than that of the V-Moda M80 (-10), Noontec Zoro (-9), and CAL! (-8).  It is also better than that of the full-size UE6000 (-14) in passive mode---this surprised me.  Equal broadband isolation may not mean equal results in all applications.  For example, the Cityscape Downtown was observed to be better at cutting off speech than the hd25, but not as good in cutting off droning noise.  The measurement sheets include an isolation graph plotting attenuation of external sound vs. frequency that can be used to distinguish a headphone's suitabiity for a particular application.

Where can I access the measurements of the Onkyo iem?

Tyll Hertsens's picture

I'll post them up next time I do an "Monthly (HA!) Update" but I might wait until Joker does a review if he decides to do so. The measurements are very good though.

hello,

has Sennheiser tricked down the cups from the now discontinued Amperiors to a new set of cans?

that would be a good thing.

Lawk's picture

The Amperiors were what? 350 retail? The older HD25 is around 169-199 here. I don't think a 150 usd/eur price bump is warranted even with higher quality aluminum cups.

I think the HD 25 Aluminium at 249 makes more sense.

There are clearance sales out there for the Amperiors though, here sometimes for about 125.....then it is a very good deal.

MarcoGV's picture

Tyll, thank you for the excellent review.  I wonder whether you have compared them with the  Pioneer SE-MJ591.  This is a (very) portable closed on-ear headphone from another mainstream Japanese manufacturer that was very much liked by Sam Tellig in Stereophile and has elicited a wide range of opinions on various sites.

Tyll Hertsens's picture

...but I'll look into getting a pair.

woody's picture

Hi Tyll,

 

I thought Sennheiser had not gotten to release the HD25 aluminum in the US just yet. Did you happen to get a pair of HD25 aluminum already? And since I remembered you said in your review that the Amperior was raelly entry level audiophile vs good Mid-hi, how does the Onkyo compare to the Amperior then, if you have any recollection of it? Thanks.

Tyll it's great to see some new budget cans that sound really great for the price, But will we ever see a higher end closed headphone review? Maybe the Fostex Th-900 and Th-600? I know the new Denon's were a dissapointment but the Fostex's have been praised around the forums. 

Tyll Hertsens's picture

I found the Fostex cans a bit too strident for my tastes. 

See impulse response for somewhat too edgy response.

Any thoughts on the new KEF M500, on-ear too, heard a lot of hype from headfi. Even though it is pretty much twice as expensive as the fc300, any idea how do they compete each other?

Heartstringsnote's picture

How about the KEF M500, Sony MDR-R1, and fc300 in comparison to the Sennheiser Momentum too? :) 

Tyll Hertsens's picture

Trying to get my hands on some.

Regards, Tyll! Could you please put some words here about comparison of sounding of this cans and MDR-1R?

I agree, the prices on Headphones seem to be going up and up and up. I love my instant gradification as much as the next person, but a little self control goes a long way.

I finally purchased a pair of Amperiors (Thank You Blog Site for informing me the Amperiors were to be discontinued). I paid a little less than half retail price.

I am a little concerned with the low price. On the official Sennheiser site they inform you that: "[V]erifying products comes in the form of a smartphone app: all you have to do is scan the security label’s QR code using your smartphone or tablet-PC to open www.qr-sennheiser.com thus starting the authentication process – there is no need to enter the ID."

I feel better.

Next. Not for nothing, but the Onkyo ES-FC300 and ES-HF300 cheated. The main reason to purchase an on-ear headphone is for portability. The Onkyo should sound as good as a "real" on-ear portable headphone - They are about the size of a closed, over ear headphone. They are neither "portabile" nor something I would wear out-of-doors.

Just Saying.

I don't know but the looks remind me a lot of AKG k550. And I'm quite surprised they're not over ears. But then again it might be for some.

Hi Tyll, really need your advice. I've lost my Creative Aurvana Live (CAL!) some times ago, pretty much like it. The sound was very good and suit my taste. For replacement, bought V-MODA M80 in order to get more portable headphone, but quite disappointed with the sound and sold it. I can't describe it but IMO CAL! is more hi-fi than M80.

What do you think about this ONKYO compare to those headphones? Appreciate your suggestion. Thanks.

Tyll Hertsens's picture

I found the Onkyo more open and even in response. The CAL treble is more artificial sounding to my ears.

6 months ago, I might've jumped at the chance for an affordable, highly-reviewed set like this loosely labeled as 'on-ears', but having had terrible fit issues trying out the DT1350, I'm highly suspect of these given the larger cup size.  If the foam isn't ultra-soft and collapsing, then the cup side closest to the face will probably sit on the back of the cheekbone & prevent a good seal.  The DT1350 made me realize how little a small sound premium matters if the user experience is a hassle, or otherwise compromised - took me 20 minutes of nudging & tweaking every time I put them on just to make the fit feel acceptable.

What nearly everybody misses about M-80s is those nice narrow profile cups - so easy to get them on your ears for the intended seal, no matter how your head or ears are shaped.  Until they release an updated version, likely to be my sole on-ear set for years to come.

I agree about the sound, my ES-HF300 sound excellent. I'm selling them, though, as I just can't get comfortable with them. If anybody is interested in buying them, check them out here:

Sorry, my bad. I was looking at the top of the heap. I forgot that they were so cheap :)

Thanks for writing the review of these Tyll. I just got the ES-FC300, and they sound great. While I have not tried them head to head yet with my ATH-M50s, I definitely do like them better. Seems like a more natural overall sonic signature. 

Magnetorheological's picture

Hi Tyll, I saw your excellent review a while back and just recently decided to pull the trigger after I had a chance to audition them while on vacation in Hong Kong. I just received my pair of HF300s a couple days ago, and I love the excellent sound signature especially at the price I got them for!!

Anyway, my question is about the durability of these cables...I admit I am unfamiliar with MMCX connectors, and I am unsure about the durability of them. I noticed that they take quite a bit of force to pull out of the housings(maybe I am doing it wrong?), and I was wondering how long they will last if they were removed/plugged back in with relative frequency.

thanks!

Just got these and these sound really good.  However, if the Sennheiser Momentum, basically an on ear headphone, gets to hand out with the big boys (the circumaural cans) then these surely do.  Someone on the market for an on ear can won't really be into these.  They fit more nicely with the circumaural crowd.

I wanted a headphone in the range of 120 to 150. And I have so many choices including the one not yet mentioned on innerfidelty the Noontec Hammo! I had the zoro and I purchased it thanks to your review and I loved them!! Now its time to get something new and I have the choice of Onkyo, Noontec hammo, Athm50 and DT 1350. Which one would be a decent upgrade to the noontecs because they already are amazing for the price?

briker's picture

Hi, I need a bit help here, you reviewed both headphones how they compare to each other? Regards from Croatia!

lukmancs's picture

Great review Tyll!

I'm still confused, which one is more worth to buy actually? HF300 or FC300? Which one is more durable (the cable)?
I listen to 320 kbps MP3 and FLAC songs, all kind of genres.

Thanks!

These are not Onkyo's first headphones. I still have a pair of Onkyo DP-300 headphones. Still working since 1992. Photo here:

So subsequent Onkyo headphones still use the 300 designation.
