The HD650’s earcups are wider than the P7’s, making them more comfortable in my opinion. The P7’s get uncomfortable after about an hour or so, leading me to make adjustments. With the HD6xx (600 & 650), I hardly ever have to make an adjustment. They are just ridiculously comfortable, and live up to every bit of hype.
The P7’s have a mic for taking calls while the HD650’s do not.
The P7’s have an iPhone control while the 650’s do not.
Frequency Response. The 650’s is 10-39.5kHz, while the P7’s go from 10-20kHz.
Sensitivity. 103 dB for the HD650 vs. 111dB for the P7.
Impedance.What is Headphone Impedance? The HD650 has an impedance of 300 Ohms and will need a separate amplifier to reach it’s full potential. I wouldn’t advise purchasing them without an amp in mind already. The sound will be much too quiet and not very enjoyable. How to choose a headphone amp! If I were to make a recommendation, I would go with the Schiit Magni/Modi to start, or substitute the Magni for the Vali. It seems to do better with 650. The Magni is a great entry level solid state amp that pairs extremely well with the 600, while the Vali is a phenomenal tube amp hybird that pairs well with the 650. Tube amp vs. Solid state.
Weight. The HD650 is 9.2 oz vs. 11.23 for the P7.
Chord Length. 120″ for the 650 vs. 52″ for the P7.
Adapter. The HD650 comes with an 1/4″ adapter included, while the P7 does not.
Volume Control. The P7’s have a volume control while the HD650’s do not.
Material. The 650’s are made of plastic and some titanium, while the P7’s have elements of Aluminum, leather, and stainless steel.
Sound. Both are on the warmer side, but the HD650 is much more detailed and articulate than the P7. The bass on the P7’s is a little over blown at times, while the 650’s is smoother and more detailed. While the mid-range on the 650’s is it’s bread and butter, the P7’s mids are a little questionable. It can become a bit lost at times, as if there’s this thin layer of mud covering the sound.
If you’re in need of an open back, extremely comfortable headphone with some added bass emphasis, and you’re willing to spend the money on an amp, the 650 is the solution for sure.
If you’re looking for my top recommendation overall, and more of a snappier, detailed sound, the HD600 is the best headphone on the market in terms of immediate price to performance ratio. Interested in learning why?
