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 Neutral and detailed sound
Treble is quite detailed, but lacks a bit of sparkle on the highest frequencies as they are rolled off. The mids are just right, not too forward and not too rich. The bass has good presence and punch, but is not very powerful.
Pro Very good passive noise isolation
Its closed back design along with the fairly thick, leather-surfaced earpads are very effective at keeping the music in and the ambient noise out. This is very useful in tracking situations, and will also help you focus on the audio even when in a busy, noisy place.
Pro Fairly comfortable on the head
The headband and ear cups have fairly thick padding to ease the pressure on the head. These are covered with leather material so they feel smooth.
Pro Sounds great even without an amp
A headphone amp is not required in order for these to pump up good volume and sound details, so these can work well off of portable devices. There is a noticeable improvement in sound quality and volume when used with a proper amp though.
Pro Build is solid and feels durable
A combination of high quality plastics and metal are used for these so there is minimal flex and rattles. The headphone joints and yoke also have smooth movement, which make these feel premium when held.
Pro Cables are easily replaceable
The cables can easily be detached, with 3.5mm jacks as ear cup connectors. This makes looking for new/replacement cables very easy.
Pro Can be used for taking calls
Stock cable has an in-line microphone. Not only is this convenient for taking calls while listening to music, but the mic's sound quality is good, with voices sounding clear, full and with good volume.
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 Headphones may feel warm and sweaty quickly
While the leather surfaces feel soft and smooth on the skin, they also trap heat very well. You may feel the warmth building up quickly around the ears and on the head. This can also be an issue if you sweat a lot.
Con Ear pad openings are quite small
If you have large ears then the small ear cup opening may be a problem. They may feel tight around the ears, or even sit on your ears instead of go over them, which you may find to be less than ideal.
Con Weight is on the heavy side
The use of metal and quality plastics on the headphone construction, as well as the magnets in the drivers contribute to a hefty weight. While this is not a problem to wear for short periods, you may feel some head or neck strain when using the headphones for hours. This also makes the headphones an extra challenge to bring on the go.
