Feature Comparison

Let’s do the ultimate comparison of AKG K712 vs HD650. Here are the main features: 

Design: Both AKG K712 Pro and Sennheiser HD650 are open-backed over-ear headphones with stereo speakers and detachable cables. But the AKG is about 30gms lighter when compared to the Sennheiser. 

Connectivity: Both these headphones are connected via a 3.5mm male connector. The HD650 has a ¼” jack with a 3.5mm adapter. 

Battery: As both of them are connected via wires, there are not dependent on batteries. 

Drivers: For AKG, they say “carefully selected transducers” and we couldn’t find the size of the drivers. They give out more bass and treble than the older AKG models. 

In comparison, the HD650 clearly states that they have neodymium magnets. The effect is in the quality of the sound. 

Sound Quality: The neodymium magnets and the higher frequency response of the HD650 gives crispier trebles, while the K712 Pro’s very low impedance and higher sound pressure level means that the AKG gives louder audio. 

Speaking of sound quality, if you are looking for more professional-quality audio for mixing purpose, AKG K702 would be a great option to consider. In a separate post, we have compared AKG K702 vs HD650 side by side to help you find the right audio gear for your purpose.

Weather Sealing: Neither the K712 Pro nor the HD650 are weather-sealed, unfortunately. This means that while they both give comparable audio, neither can be used in all weather conditions. 

Comfort: While both these headphones fit over-ear, the soft velour and leather headband of the AKG K712 Pro has an upper hand in terms of comfort. It weighs a little less as well, so the contest is kinda given to the AKG.

Price: HD650 is about one hundred dollars cheaper than the competition. This may or may not make a difference in the final verdict. 

Final Verdict- Which One Should You Choose?

The audiophile may choose the HD650’s precision of crispier trebles and bass with the wide-open soundstage over the loudness of the K712 because the former gives you all that you want and more. 

For the music professional, however, the question of  AKG K712 vs HD650 clearly favors the former. These are the reasons: the K712 is super comfortable, with a very low impedance and dynamic open back quality that gives you a wide soundstage that all sound mixing professionals can swim in.
