Years ago Sony released MDR 7506 Professional Large Diaphragm Headphones designed Specially for Recording & Mixing Engineers who needs to focus on any Noise & Distortions in the Recording & Mixing process. Obviously the Bass is toned down with mid and upper mid-range tonal balance enhanced for clarity…. Subsequently MDR V6 made available with certain enhancements to handle more Frequency Range in the Low as well as Higher frequency range.

Conceptually both Both Sony MDR 7506 & MDR V6 have the overall same Sony sound signature. The build including 40 mm drivers backed up by Neodymium magnets, these over ear type designs are almost similar.

Both Sony MDR 7506 & MDR V6 headphones are preferred by Live DJ’s due to the fact that the prominent mid-range tones helps to focus them on quality suppressing down the crowd noise and environment disturbances.

• Impedance
  Both of these headphones have the same impedance, which means they both require the same amount of power to produce a certain volume level.
• Frequency Response
  The Sony MDR V6 can deliver a larger frequency range of pitches with a lower bass and higher treble output. Although human ears can only hear around 20 Hz – 20 kHz, purpose of giving this extra range is purely assist the Expert Sound Engineers.

Lets have a look at Technical specs & features comparison of Sony MDR 7506 & MDR V6, appropriate colors being used to show the differentiation.
