Summary: The praise that has been heaped upon the Sennheiser HD650 headphone is something that probably every headphone OEM envies. The HD-650 is nearly a decade old and yet is still viewed by many as a top tier dynamic, worthy flagship, and is the benchmark that many measure price to performance ratio...
Pros: Smooth Presentation, a linear, stout sound at louder volumes.
Cons: build quality is meh! Overall sound is too recessed and lacks weight
Summary: Review Equipment:
Amplifier: Matrix M-stage (Audio-gd SUN v2 HDAM)
DAC: Matrix ASRC Cube DAC, Valab NOS DAC (v2.6)
Other headphones: AKG K702, ATH-ES7, Beyerdynamic DT770, Sennheiser HD555
Great packaging. The HD650 came in a hard box lined with tons of foam padding on the inside.
Summary: My first Sennheiser was the HD555, which was a real gem for its price bracket, and then when it broke, I replaced it with the HD600. I immediately exchanged it for the HD650 as I found the HD600 to sound so similar to the HD555 (just a little bit more treble mainly) that the price difference wasn't...
Pros: Smooth, non-fatiguing sound, comfortable, well-balanced sonic signature
Cons: Sub-bass could be deeper, treble could be slightly more airy
Summary: This is my second round with these "holy grail" of headphones. First time around I was just laughing at it's meager power capability. The sound was good, but not mind blowing. Zero sub bass control, with ok bass.impact. I got the Hifiman 400i and couldn't be any happier.
Summary: The Sennheiser HD650 truly offers an incredible experience and once you listen to it for a while, there’s little doubt left as to why they are so popular. The Sennheiser HD650 are pricey, without a doubt and they’re not value-for-money, either.
