For example, instead of the protective grille on the outside of the headphones, here there is only a fabric covering. While somewhat lacking in the high mids and high highs, the overall impression is one of general quality.

There's not a lot out there, but I was able to find enough matches to my query that prompted me to pull the trigger on these. Sound pressure is low compared to closed-back models, but on-par with other open-headphones, and the harmonic distortion is decent. A substantially broken seal will result in less subbass but the bass ‘hump’ will not be affected much.Another thing I immediately noticed was it sounded kind of muffled, like vocals were recessed from the rest of the spectrum. I went between them for a few hours and i'd say its closer than it should be but the HD600's still win.

After putting them on I can say they are a really comfortable pair of headphones, that's where the good things stop.

i dare go too high as i need to check with the rigol oscilloscope if the signal is going to clip or curve of the sine wave goes flat at the top of the voltage level as should be nice curve at the top end . Sennheiser HD 5 model range offers high quality and value in any aspect powered by Sennheiser’s proprietary transducer technology including the “Ergonomic acoustic refinement” (E. Something was missing in the music and although listenable as-is, once you know the correct tonality of music you wish for more. The plot above shows the level differences between the signal (upper trace around 85dB SPL) and the harmonics. Distortion levels in the lowest frequencies are 3 rd harmonic dominated pointing to compression alike distortion.The DT990 also has an emphasis in the lows (U shaped sound) but is lower in frequency so less boomy and not hollow. A few years ago, I could find no fault in these headphones, but tastes and experiences change, I guess.
