![]() Given its high efficiency (110dB 1V) and low impedance this is a very viable option. The K812 thus can also be connected to phones and DAPs with a 3.5mm TRS jack. The cable terminates in a 3-pin 3.5mm TRS jack with a scre-on 6.3mm adapter. The cable isn’t thin but also not ‘audiophile thick’ and 3m in length and just mildly microphonic. Just like the Beyerdynamic DT1990 (and DT1770) there is only a 3-pin connector so going balanced is not an option. Partly because of this construction and the fact that the connector does not plug directly into the left cup there is very little microphonics from the cable as it doesn’t rub against clothes and is not directly coupled mechanically.Īs some headphone enthusiasts prefer balanced or 4-wire cables on their headphone it is kind of surprising to see there is no possibility for this, given its price class. The cable thus also does not have to bend. The (excellent but expensive) LEMO 3-pin connector comes straight down from the left ear-cup but is placed more in front of you so the cable drapes in front of you instead of on your shoulder. L and R markings are located on the inside headband on the height adjustment parts.Īnother give-away for identifying the left cup is the cable entry. Not having these elastic bands is a blessing fro longevity as all the AKG headphones using the elastic bands gave up being elastic after a few years already and are not easily replaced by the owner. I guess this is the downside of not having the auto-adjustment elastic bands while adhering to a similar construction of the headband. When it is set to the lowest position and you ‘stretch’ the headphone a bit to take it off the setting changes (with a ratteling sound because it changes a few ‘clicks’).Įvery time I put it on I have to re-adjust the height which is annoying. The headband is cloth covered, it does not push hard on my head. The headband can adjust over a fairly wide range and clicks quite firmly. The reviewed and measured K812 has seen quite a few hours on it already so it isn’t a new version. In 2019 the going price is around € 800.-īoth of these are the AKG Top- Of- The- Line headphones. The AKG K812 is an open dynamic headphone which is quite expensive (MSRP = € 1500.-). The bigger the deviation the stronger the effect.īelow an aid to help determining the sound character of headphones with relation to the frequency response. Deviations in different severities at different frequency bands have an effect on the sound character. A horizontal line shows audible neutral response in the plots on this website. ![]() 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.įrequency response (tonal balance) is the most sound-determining aspect of headphones. This is described HERE in more detail.Ī ‘ horizontal‘ frequency response curve on the shown frequency response plots on this website thus indicates a perceived ‘flat’ tonal signature.ĪLL measurements are made with a good SEAL on a flatbed measurement rig. I do not use smoothing because some info about sound quality is lost when plots are smoothed.Īside from a small correction of the microphone itself also some correction in the lowest frequencies is applied to the plots to compensate for the perceived loss of bass when using headphones. Most measurement sites have some smoothing applied which ‘irons flat’ sharp peaks and ‘wiggles’. NO SMOOTHING is applied to the shown plots. power, efficiency, levels, balanced, impedance.Foobar 2000 for Dummies (Part 2) – Playing DSD – SACD plugin.Foobar 2000 for Dummies (Part 1) – General Setup.Subjectivist, Objectivist or Inbetweenivist ?
