Pros
Pro Great sound for the price
An overall balanced sound with slightly emphasized bass. It's not thumping bass, but it's not anemic either and it doesn't bleed into other ranges. Mids and highs are clear with no sibilance. There's close to no distortion in any of the frequencies. Even the soundstage is fair for the price--while it's still rather cramped, the instruments are separated out enough for them to not sound like they're all coming from the same place. It's a sound quality that's typically present in earphones that are in twice as expensive.
Pro Very comfortable for everyday/casual use
The earbuds are light and small with an angled nozzle, fitting most ears comfortably. It's comfortable to wear both over and under-ear.
Pro Will last you a long time
V1S earphones have a metal housing, strong rubber wires and a durable rubber stress relief to make sure that the earbuds last. However, they aren't water resistant.
Pro Good noise isolation
The IE 800s allow some ambient sound to pass, but not enough to be bothersome.
Pro No bass distortion at any volume
Precisely engineered pressure vents behind a single dynamic driver leave no opportunity for distortion to occur.
Pro Ear tips provide a good seal
The ear tips are a step up from the common silicone ear tips on the market today. The part that comes into contact with your ear is made out of soft, flexible, high quality silicone. The inside canal of the ear tips however is made out of a firmer plastic material, with a metal mesh in the middle.
This combination allows the ear tips to create a very good seal when worn, reducing sound leakage/bleed while also ensuring optimal sound delivery.
Pro Fantastic listening experience
Sennheiser is known for audiophile gear, and these earphones qualify. Their frequency response, dynamic range, and clarity of definition do justice to their price tag.
Pro Good durability with scratch resistance
Instead of using metal or plastic in the construction of the earpieces, Sennheiser has used a special ceramic material on the IE 800 which is scratch resistant. This helps to keep the weight of the in-ears down, yet can still withstand use and abuse pretty well.
The cable on the other hand is very high quality and covered with Kevlar reinforcement for added durability.
Pro Oxygen-free, kevlar-reinforced copper cable
Wrapped and sealed in an oxygen-free environment, these cables are immune to corrosion so long as their tough kevlar shielding remains intact.
Cons
Con They don't handle water or sweat well
They aren't sweat or water resistant.
Con Not a good option to use for exercising.
Along with not being sweat-resistant, they tend to slightly move around in your ear regardless of chosen eartips. This can be distracting.
Con Some cable noise is present
Cable movement will result in unwanted audio signal that can interfere with the listening experience on lower volumes.
Con The L-shaped plug can put stress on the cord
Con Cable noise
Touching the cable or rubbing it against clothing makes a rustling sound that transmits into the earpiece.
Con Y-split connection can pull down the earpieces
The detachable cable after the Y-Split cable adds a bit of weight to the earpieces. This can pull them down and cause them to dislodge at times.
Con Does not come with an in-line microphone/remote
While not really a CON, this omission can make or break your purchase decision for these headphones. Sennheiser offers an add-on cable which features the mic and remote, but is quite expensive.
Con Headphone cable is not completely removable
While the headphone cable can be attached/detached via a 2.5mm connection from the Y-split down, the cable cannot be removed from the earpieces themselves. This can make replacing the fixed cables very difficult and potentially expensive.
