Sennheiser HD 559 Open Back Around Ear Headphone - Black/Anthracite

Product Information

Below a comparative measurement of the HD559 and its more expensive bigger brother HD599 Bass extension is the same.

As this is a dynamic headphone the frequency response can be amplifier output resistance dependent when certain higher output resistance amplifiers are used.Desire to learn and share knowledge of science required as is 20 years of participation in forums (not all true). While I can't tell if the smoothness I'm hearing in some recordings is just because these headphones are forgiving or if the dac truly makes the difference, I can say that the HD 559 does pick up the improved sound of cymbals that the multibit dac provides. The oval cups give plenty of room for the ear and the pads don't touch the ear at all, giving a really nice feeling of freedom.

I personally don't like leather pads and headbands as they tend to be a magnet for the slightest trace of sebum on your skin or hair (requiring cleaning almost every time you use them) and leather also tends to make your ears get hot after longer periods of use. The construction of these phones is sturdy and has a reassuring 'feel' of German quality, also unlike some phones I have tried, they do not creak or groan as you put them on, remove them or move them about on your head.I do really like these and my experince with them is motly positive but I do have some gripes very minor ones but still important to mention.
