The effect of this filter is described in the K702 page. I swapped out the foam disc in front of the drivers for a different material. The signal doesn’t follow the stimulus in the horizontal plane and quickly drops down. Impedance: 62 Ohms. If you are using a screen reader and are having problems using this website, please call (888) 452-4254 for assistance Looks beautiful, CHANGSTAR: Audiophile Headphone Reviews and Early 90s Style BBS, AKG K701 Frequency Response and CSD Waterfall Plots, Topic: AKG K701 Frequency Response and CSD Waterfall Plots  (Read 17382 times), Re: AKG K701 Frequency Response and CSD Waterfall Plots, https://www.facebook.com/SchrodsonkMuseum, Quote from: shipsupt on June 20, 2013, 09:21:01 PM, Quote from: hans030390 on June 21, 2013, 05:51:37 PM, SimplePortal 2.3.5 © 2008-2012, SimplePortal, Master of Revelatory Bird Calls and Fine Art. S.P.L. Home. The AKG K701 has a foam ring covering the driver. I recently heard about sonarworks reference3 which seems to be the better and more in depth going alternative to arc2 which i am using. There is hardly any difference. SPL is 105 dB at 1 volt into 62 Ohms. If you were interested in purchasing the K702, I wrote about some great choices in my article AKG K701 vs. K702. The fact that it has a long cable suggests it is not intended for portable usage. In terms of sounds, the frequency response is relatively flat without any emphasis on specific frequencies. The AKG K271 is easy to use but doesn’t suffer for its simplicity. Below the frequency response of the K701 (Left, Right) Channel matching is excellent. voltage: 3.5V The impedance of most consumer grade headphones is usually rated at 1mW. I do not use smoothing because some info about sound quality is lost when plots are smoothed. The bright ‘neutral’ signature can be improved by EQ or as described above. 2. highest frequency. AKG K702 is a pair of neutral open-back headphones that is designed for professional studio use. The plots above show the ringing is substantially damped by the thin ply of toilet paper. These pads are really easy to remove. The impedance (SPL sensitivity) of the K701/K702 headphones is rated in relation to 1 Volt, as are most studio grade cans. Home > Headphones comparison > AKG K701 vs Yamaha HPH-200. Now I wonder how the k712 will sound. (website links), Foobar 2000 for Dummies (Part 1) – General Setup, Foobar 2000 for Dummies (Part 2) – Playing DSD – New SACD plugin (0.9.x and 1.x.x Series), power, efficiency, levels, balanced, impedance. Above 100Hz the distortion stays below 1%. AKG K701 vs Yamaha HPH-200. On the left the (very thin) toilet paper single ply and on the right the same but with the foam ring placed on top of it. AKG K702 Box. What’s obvious here is that these pads won’t improve the bass response but rather slightly (2dB) increase the mids and deepen the 4kHz part which makes the sound less ‘forward’ and less bright. It just doesn’t play very loud directly from a  phone and requires quite some volume for the bass to ‘snap’ into the correct level (Fletcher Munson / equal loudness contour curves). current: 56mA are over-accentuated. A filter for the K701 has been re-designed based on the measurements above. Another way of reducing the treble peak is by using a passive in-line filter in the headphone cable. The tonal balance is hardly changed when listening to these headphones with or without glasses. AKG k702 frequency response. The mids are less accentuated when using these pads and ‘mellow out’. The k701 comes with a presentation stand and 6.3mm adapter. To compensate for this the amplifier is cranked up to the same level (9.4dB at 1kHz) as the low impedance amplifier. This is described HERE in more detail. 11 December 2008 Summary. beyerdynamic DT 990 pro VS. AKG K702 Advice. The 3rd harmonic and higher harmonics distortion is below 0.5% in the bass area (40-200Hz) which is decent. Frequency response (tonal balance) is the most sound-determining aspect of headphones. Driver size: ø 40mm from folks on Head-Fi. The step response plot below  (Left, Right)This plot shows the impulse response/clarity is accentuated and peaks out 3dB above the mids. Max. It does not push hard on my head but one does feel a small contact point and the cups have a small tendency to drop a little lower in my case. Unfortunately, it's not available for win7 yet. Some headphones have cable entries on the right. ''I'm a music lover. The flatter the frequency response – the higher the score. The AKG K712 is a direct descendent of the classic K701, using a very similar physical design, but a different driver. The K701 is much more ‘neutral’ but is lacking in the lower bass. 39800Hz. Below an experiments with a disc made of soft 3-ply toilet paper where the plies are cut into discs and the 3 plies are pulled apart to form 3 very thin and fragile discs. Below the CSD of the K701 but with the toilet paper disc added. Yamaha HPH-200 $ 79. The pads are large enough in inner diameter (55mm) and have a nice depth (25mm) so most ears will fit. Below the K701 vs the K7XX. The dip at 4kHz deepens which removes even more of the bright character of the K701. Usage: Home, Studio L and R markings are located on the headband. The only real longevity issue is the elastic bands that aren’t easily replaced by owners. Quand on passe de l’un à l’autre la première sensation est que le AKG … AKG K702. This shows the resonances are effctively damped. Below the tonal balance differences between the old rivals K701, DT880 and HD650. Efficiency: 90dB/1mW (102dB/1V) Material: Leather headband, plastic, memory foam. NO SMOOTHING is applied to the shown plots. The AKG K701 is a an oldie. This makes the bass sound ‘light’ but ‘tight’. I've never heard anything from AKG before. Below the frequency response of the K701 (Left, Right)Channel matching is excellent. Below: Perfect seal, a small seal breach by thin armed (reading) glasses just above the skin, thick armed glasses and a big seal breach.A seal breach isn’t really problematic at all. Beyond 1ms the signal drops gradually and shows the bass roll-off. On the left 40Hz, in the middle a 440Hz square wave and on the right a 100μs wide DC impulse.The bass roll-off is easy to see in the 40Hz squarwave. The clamping force is medium and pleasant but this particular headphone has already been worn for quite some time. vs. vs. 17 facts in comparison. It is a bit bass light but the bass itself sounds excellent and well textured. Don’t think this is very detrimental to the sound. akg k371 frequency response graph. I can't remember. A give away for the left cup is the cable entry as well. Below an aid to help determining the sound character of headphones with relation to the frequency response. I think the dome section of the driver needed bit extra damping. Colour: white or black Frequency response: 10Hz to 39,800 kHz. Collapsible: no The foam isn’t doing much here. This way the plots are overlay-ed and it is easier to show the tonal balance differences.The headphone does not react much to higher output resistances other than in level (9.4dB). What I did was messed with front to get them sounding to my liking. Cable entry: left sided. It sounds a bit too bright and can have a shrill ‘edge’ with some music. Beyond studio uses, closed-back headphones are perfect for casual listening, listening at the office, and commuting. ALL measurements are made with a good SEAL on a flatbed measurement rig. There is only one big downside (which is still a problem with similar looking AKG models) which is the elastic bands loose their elasticity over a few years already. Changing pads usually results in a quite different tonal balance. The treble is over accentuated and has enough ‘air’ but isn’t really ‘smooth’. The K701 is very easy to drive though with its 62Ω impedance. AKG is the first manufacturer in the world to use revolutionary flat-wire technology in headphones, namely the K 701. Below the frequency response measured with and without the foam ring. AKG K701 review These AKGs are beautifully built and feel like they’d survive years of use with ease, but there are more entertaining headphones out there Tested at £250.00. The frequency response +/- 3dB is 30Hz-10kHz. Headphone connector: fixed entry. Max. As the seal of a headphone is of importance some experiments are done to see the effect. AKG Black K361-BT 1/8" (3.5 mm) TRS Connector Circumaural Over-ear, Closed-back, Foldable Studio Headphones with Bluetooth. 300Hz Squarewave Response It was founded in 1947 by Dr. Rudolf Görike and Ernest Plass in Vienna, Austria.It is a part of Harman International Industries, a subsidiary of Samsung Electronics.. Around 2.5kHz there is a little lingering (the small bump in the FR, it seems happy to vibrate at that frequency) but is very low in level. 2. highest frequency. Below the same plot but the mids are overlayed. The headphone feels and is quite sturdy. One difference between AKG K712 Pro vs HD600 is that AKG K712 Pro comes with two cables, instead of one. The foam is just lying on the driver and pressed onto the driver using netting integrated in the pads. Above 18kHz the response drops off quickly but still shows response at least up to 30kHz. Sem categoria The ear cups enclose the ears and offer sufficient horizontal and vertical play so that the headphones fit snugly to the head. type: open back fit: circumaural (over ear) impedance: 250 Ohms frequency response: 5 Hz – 35,000 Hz material: velour ear pads, rugged plastic, metal headband: spring steel, soft cushioning … vs. AKG K712 Pro. They can be replaced but is expensive and not easy to DIY. The cable terminates in a 3 pin 6.3mm TRS jack. 35 points. Since they're completey open air there is no point to mess with the back of the driver for modding. They have two-tone navy blue and silver color scheme and an old-school retro design that will work for some. In days gone by the K701, Beyerdynamic DT880 and Sennheiser HD650 ruled the consumer headphone world and each had/has their own fanbase. The AKG K701 has a ‘bright neutral-ish’ tonal balance. Drum hits etc. The treble is lowered by 1 dB as well so these pads make the sound of the K701 less ‘bright’ and less ‘forward’. The result is a claimed frequency response range of 10 Hz to 39.8 kHz – on a par with headphones costing north of £1,000 including the much-lauded … If you like the crispness of the colour white, you’ll find it hard to avoid the allure of the K701. These headphones do not emphasize any part of the frequency response range; everything is sounding exactly like the source. For the going streetprices (around € 130.-) this is a good and comfortable headphone that can take a beating. Below the step response of the stock K701 and via Kameleon (both with toilet paper mod)The bass response is improved a lot, alsso the ringing and peaking is a lot lower in level. The lower the low-frequency response, the stronger and juicier the bass. The only artifacts of note are the slight differences in lumpiness between 900Hz and 2000Hz, and about 3-4dB lower energy above 10kHz on the Q701. The headband can adjust over a wide range but isn’t padded. The ringing goes on for quite some time and is seen in the entire plot. Frequency response is flat from 10Hz-39.8kHz – well beyond the range of human hearing. Type: On-ear, open Of course this is there for a reason. Only the artificial leather elements are darker in town, in this case a brown shade. The ‘details’ in the music are ‘fake’ due to the 6.5kHz peak. Isolation: low (open headphone) Equipment Forums. (lots of) hair between the headphone and ear or an ear shape that does not allow a proper seal will affect the tonal balance. Below the stock K701 (but with 1 ply of toilet paper) vs driven by the kameleon (also with 1 ply of toilet paper), Bass response is extended and lifted in amplitude, the 2kHz peak is now at the same level as the mids and the 6kHz peak has been lowered to normal levels. Driver type: dynamic Fig. Apparently the pads are different (confirmed) and the drivers are cherry-picked and closely matched (AKG's claim). Below the K7XX vs the K701 but fitted with K7XX (K712) pads. SEGMENTO. Even though the manufacturing of these headphones has brought in a few plastic elem… 1 Shows the frequency response of the AKG Q701 (top) and the AKG K 701 (bottom). Comparison winner. D3 is just too high over 0.1% to 800Hz. The AKG K701 is a sturdy work horse. The shape of your head, bone structure, pad size, pad ‘softness,  (compliance), hair or no hair and or wearing glasses may (drastically) change the frequency response of some headphones, so… your personal experience may differ substantially from these plots. 0 Members and 1 Guest are viewing this topic. But.. no increase in bass nor bass extension. Bi-wired oxygen-free copper cables optimize channel separation. This plot looks quite good below 500Hz. It is only available in white with grey/brown accents. The output resistance of the used source/amplifier has NO practical influence on the sound. Bass extension isn’t great and it starts to audibly roll-off from 100Hz down. Yeah, well, you know, that's just, like, your opinion, man. The cable isn’t thin but also not ‘audiophile thick’ and 3m in length and just mildly microphonic. According to some audiophiles, it may take sometime for the headphones to be broken-in (100 - 300 hours). Some reason akg knows what they're doing with the acoustic material and found it do well to keep the the bass output evened out. To test this the headphone is measured via a low impedance amplifier (0.2Ω) and a high impedance amplifier (120Ω). These pads aren’t cheap though. Then, if you like me care for ergonomics and outstanding comfort, you most probably find that AKG K701 has it. The headphone is light in weight. AKG K701. Below the square-wave response of the K701. Only a very narrow resonance remains. It is often mentioned the K701 is ‘hard to drive’ which is nonsense. The bass response is full, accurate, and tight. Max. Hence, AKG K702 has been praised as an excellent tool for making music. That eventually narrowed the choice down to AKG and the the K601 or K701. The imaging can be adjust slightly by moving the ear pads around your ears. Most single entry headphones have it on the left just like the K701. The white with grey and brown accents differs from that of most other headphones. Didn't sound bad but had had a bite to them which bothered my ears with certain tracks and the vocals sounded bit odd. This is a comfortable headphone that can be tweaked in sound by using different AKG pads. AKG K712 Pro VS. highend Game Headsets - Please Help. 32 points. Below the K701 vs the K612.The K612 (better extended K601) is considered ‘neutral’ with a forward sound and sharpish treble. Aside from the narrow 15kHz resonance (Left channel) and 16 kHz (right channel) the waterfall plot looks quite good. It is bordering on sibilance. Below the plot of the K701 with K7XX pads fitted. Bi-wired oxygen-free copper cables optimize channel separation. For an affordable headphones, AKG K701 and Beyerdynamic DT 1770 Pro are two comparable choices. As the K701 is not a high efficiency headphone this too suggests it is not designed for portable usage. Its supposedly bassier due to the memory foam. The K701 has been around for many years already, just like the DT880 and HD650 and have been surpassed as ‘TOTL’ headphones for these brands but still are good performers. Not an audiophile.''. When it comes to the frequency response spectrum, as long as a pair of headphones is capable of reproducing sound within the 20 Hz – 20,000 Hz audible spectrum, it is considered fine. 99. I think it was a type of felt. Honestly, that's my only complaint with them stock. Sensitivity is 105dB, while power handling is 200mW. These headphones are pretty highly regarded, although they kind of fly under the radar. I've also been experimenting with using a larger foam disc that goes over the felt ring (covers hole in middle as well). As this is a dynamic headphone the frequency response might be amplifier output resistance dependent when certain higher output resistance amplifiers are used. Below the K702 vs the K701 The highest frequency at which device produces audio. A ‘horizontal‘ frequency response curve on the shown frequency response plots on this website thus indicates a perceived ‘flat’ tonal signature. The lower the low-frequency response, the stronger and juicier the bass. Also, because the K701 has less bass/mid-bass/lower-mids the treble/brightness is relatively much more accentuated.
