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 Bluetooth connectivity minimizes the hassle of wires
Connectivity with source devices is via Bluetooth, so in place of a full headphone cable is a flexible, soft and short cord made of rubber material that keeps the earpieces connected. You won't have to deal with a long and dangling cable.
Pro Full mids, punchy bass, and smooth highs
The highs are not the most detailed, but they are clear and do give an airy feel to the music. The mids are full and forward so vocals will definitely sound great.
Bass is hit or miss though, depending on how well these headphones seal in your ear. If there is a good seal then bass is punchy and tight though not very powerful. Otherwise, it is likely that the bass will sound a bit on the thin side.
Pro The included case doubles as an armband
The case can be converted into an armband by reversing it inside out. This is very useful as you can use the arm band to store your smartphone while on a run, along with some essentials like your keys or some cash.
Pro Fits nice and snug in the ears
The ear tips are made out of a soft and flexible material that is comfortable and supports the weight of the earpieces quite well. This is enhanced by the wing tips that further help to keep the headphones in place.
Pro Earbud design allows ambient sound in
The design does not create a thorough seal in your ears, which can be a good thing as this will allow you to maintain awareness of what's around you.
Pro Good battery life
The BackBeat Fit can last up to 8 hours of playback from a full charge.
Pro Sweat resistant
A sweat resistant coating is applied to the interior parts, so splashes of liquid aren't likely to cause damage.
Pro On-earpiece buttons allow basic smartphone/music player function control
Each of the earpieces have a single button. Different combinations of presses will allow you to pause/play tracks, answer/end calls, adjust volume and do other functions which can be convenient.
Pro Built in microphone has a decent sound
The audio from the microphone is not amazing, but it is quite clear with no distortion so it should be good for most conversations.
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 Flopping earpiece cord can be annoying
When you start moving, it is likely that the short but fairly chunky cord connecting both earpieces will flop up and down. This can come into contact with your skin which can be distracting, and can even cause skin irritation.
Con Noise leakage can be distracting
While these headphones allow you stay aware of your surroundings, this also means that a lot of environmental sound will get in the way of your music. If you want to zone-in on your audio while running or working out then these may not be the best ones for you.
