Overall these are well designed and build headphones that provide comfort. You can use them for mixing, recording, and practicing longer sections.

They come with three detachable cables, including 1.2 meters long straight, 1.2 m coiled, and 3-meter straight cable. All cables end with a standard 3.5mm jack and extra adapter.

Sony MDR 7506 Review

Good: 40-millimeter drivers provide clear and accurate sound. These are ideal pairs of headphones for monitoring and studio work because of 63-ohm impedance and 10 Hertz to 20-kilohertz frequency response. They have excellent design and build quality as well.

Bad: The cable is not detachable, and if you want to replace it, you need to open ear cups, which is not the best option.

Design & Build Quality: They come in black color, and the overall design is good, and the build quality is impressive.

Sony MDR 7506 is lightweight than average headphones because they weigh only 8 ounces. You can also fold them and take them anywhere.

The headband is thick and has a soft padding that provides excellent comfort. The headband is also adjustable and provides a good clamping force that will not lose from the head in sudden movements.

Ear cups have a closed-back, over-ear design and are made of plastic. Earpads of MDR 7506 are soft and comfortable, but if you have huge ears, ear pads will press your ears slightly. If you listen to music at a high volume for a long time, then you may feel warm.

These are wired headphones, so you’ll get a 9.8 feet long cord that terminates on a 3.5mm jack. Also, you’ll get a 6.5mm adapter. The cable is not detachable; it is fixed.

Overall the build quality and design of sony MDR 7506 are excellent, and they fit on the head and ears very well.

Sound Quality: The sound quality of the sony MDR 7506 is good and has no flaws. They offer excellent sound, especially for studio works. 40-millimeter drivers drive them very well. You’ll find very few headphones that deliver non-overwhelming and accurate sound at a lower price, and MDR 7506 is one of them. 

They have 10 Hertz to 20-kilohertz frequency response. In simple English, lows, mids, and treble are very clean and not harsh.

The impedance of sony MDR 7506 is 63 Ohms, which offers very detailed sound. But to achieve remarkable sound on lower power devices, make sure you connect an amp that produces excellent power. On mobile devices, you may not get the sound that these pairs can provide because of low power, but these are great for studio works.

Sound Isolation: They are doing a pretty excellent job in sound isolation. Even at the lower volume, you’ll not listen to external noises. They also do a good job blocking sound leakage. At 70 to 80% volume, they didn’t leak any amount of sound, but if you increase at full, they leak a small amount of sound.

Connectivity: You can only connect them using an audio cable.

Bottom line: Sony MDR 7506 offers a beautiful and balanced sound since 1991, and for every studio, these are the ideal pair of headphones. They are durable and comfortable for extended use. The only thing they need to improve is a cable that is strong but not detachable. Overall these are good pairs of headphones available under $100.
