Pro Solid noise isolation
Once you pick the eartips that best fit you, the isolation is solid overall with double flange eartips offering the best isolation followed by other foam eartips and then silicon eartips.
Pro Built to last you a long time
IE80 earbuds use high-quality kevlar-reinforced cables with a thick rubber strain relief and the earpiece shells have brushed metal plating. A strong connector holds detachable cables in place. Additional strain reliefis added by the L-shaped plug. These earphones are built to last and if there are any issues with them, there's a 2 year warranty.
Pro Comfortable for extended periods of time
IE80 earbuds aren't fatiguing and stay in your ear confidently. While they're designed to be worn over-ear, under-ear cable routing works as well. They're also low profile enough that you can lie on your side with them.
Pro If something happens to the cable, you can replace it rather than buy a new pair
Replacement cables are around $20.
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.
Cons
Con Replacement cables are expensive as well
If you need to replace the cables, they retail for about $20.
Con Rather expensive
While these are among the cheapest audiophile-grade earphones, they're still priced at $250. It's a serious investment. And for many, just not worth it.
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.
