Pros
Pro Extremely detailed highs, warm and clear mids with tight and accurate bass
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.
Pro Highly detailed sound with one of the widest soundstages
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.
Pro Relatively lightweight
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.
Pro Very wide sound stage
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.
Pro Solid build quality
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.
Pro Comes with two high quality cables
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.
Pro Really comfortable to wear
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.
Pro Headphone cable is removable
You can just pull out the cable as needed, allowing you to easily store the headphones without the hassle of dangling cables. Also, this feature means that the cable is easily replaceable should it get damaged.
Pro Large ear pads are comfortable
The large ear cups go over the ear instead of sit on them, so no pressure is applied onto the ears. The ear pads on the other hand feature really soft and thick memory foam as well as high quality velour material on the pads' surface. These feel really soft on the sides of the head, and allows some air to circulate around the ears, minimizing heat.
Pro Pressure on the head is significantly minimized
A hammock design is used for the headband. Instead of one single headband piece, this has a two-piece design. The top, solid part is what holds the ear cups together while the lower piece is primarily made out of leather and mesh. This softer and more flexible part is what comes into contact with the head, which results in substantially improved comfort over conventional headband designs.
Pro Wide sound stage can result in an immersive audio experience
The wide soundstage heightens the feeling of immersion in in-game audio. The top-notch positional audio allows gamers to easily identify sound sources, like the movement of nearby players or the direction that bullets are coming from.
Pro Fun sound signature with powerful bass and crisp, detailed treble
The bass is really powerful yet also tight. The highs are boosted so audio details are quite prominent. The mids, while not as up front as the bass and the highs, are clear and present.
In-game sound effects will come as clear and detailed, while explosions, gunshots and similar sound effects are really powerful, making these really fun sounding gaming or movie headphones.
Cons
Con A decent amp is needed to power these properly
These headphones are quite power hungry and will not produce optimal sound or volume when plugged directly to your phone or laptop. You will need to invest in a separate, fairly powerful amp to get the best sound out of these.
Con Leaks a lot of sound
Only a very fine mesh piece covers the large headphone drivers from the outside. These are basically mini speakers so others can easily hear what you are listening to.
Con Can be picky with DACs/amps
Your choice of amp and DAC can have a noticeable effect on the sound of the HD 800S. You may need to do extra research as to which audio equipment can bring out the best sound from these.
Con Highs can be too harsh
High pitched sound effects can be more pronounced and can be quite fatiguing to those sensitive to treble.
Con These leak a lot of sound
The large ear cups go over the ear instead of sit on them, so no pressure is applied onto the ears. The ear pads on the other hand feature really soft and thick memory foam as well as high quality velour material on the pads' surface. These feel really soft on the sides of the head, and allows some air to circulate around the ears, minimizing heat.
Con Bulky and quite heavy
These are fairly large because of the sizeable ear cups and 2 piece headband design. Also, these are on the heavy side so if you prefer light weight headphones, these might not work for you.
