Sony MDR 7506 vs Sennheiser HD 800S

The bass is just right. It may not have the deep sub-bass extension that bass heads crave for, but what is there is fast, tight and punchy. The mids are clear with a hint of warmth, which make vocals and guitars sound very clear and you can easily hear their sonic nuances .
The reproduction of highs is the part that these headphones really shine. They are crystal clear and highly detailed without adding hiss or harshness to the overall sound. Cymbal crashes and pings, for example, are very close to what you would hear if they were played right in front of you.

Despite being sub $100, the MDR 7506 can compete against headphones up to twice the price. These make for great headphones if you are just starting to get serious about your audio and you want a relatively inexpensive yet quality purchase.

The MDR 7506 is built outstandingly well, with high quality materials and with little to no creaks and unnecessary flex. These headphones have been around since 1991, which has given Sony a lot of time to refine the manufacturing process of these cans.

The yokes are collapsible and fold into the headband, reducing the headphones to a much more compact size. Included with each purchase is a synthetic leather pouch for added protection for the headphones when taking them on the go.

These leak very little sound compared to other over-ear headphones. The rear side of the ear cups is fully closed, which effectively minimizes sound leakage. With these, you can fully enjoy your music without disturbing people beside you.

The highs are very clear and revealing, so you will be able to hear even the minute details from the audio that you simply will not be able to pick up with lesser headphones.

The mids are also clear and have nice warmth. They are slightly recessed, yet voices and mid range tones will come out full, so the sound is not lean in any way.

The bass is not boomy but still has enough power for a satisfying thump. Also, due to the bass' tightness and speed, there is no bloat from the lower frequencies.

These headphones sound very immersive. Aside from the highly detailed sound and powerful yet tight bass, the soundstage is very wide, which only a few headphones can match , if any at all.

Despite the massive size of the headphones, Sennheiser was able to keep the weight down by using a special material called Leona, which is very light yet has metal-like toughness.

The HD 800S has one of the widest sound stages of any headphone today. There is excellent separation and you can easily identify where various sounds are coming from and can be very immersive.

These headphones do not make unnecessary creaks or flex when moved or held. Aside from the use of Leona on the ear cups and headband, the size adjuster is made of lightweight metal, with fine yet durable stainless steel mesh covering the drivers.

Out of the box, you get a balanced XLR cable and an unbalanced TRS cable. If you have a balanced headphone amp, then the XLR cable will allow you to maximize your amp's performance with these headphones without the need to buy a different (and expensive) cable.

The ear pads feature high quality memory foam as cushions with the surface being premium quality velours. This material combo is also used on the headband. They feel really soft and conform to the contours of your head. Due to the fabric material, some air can move through the pads, minimizing heat and sweatiness.
