Great earphones
Bought these as a gift for someone predominantly using them for gaming - says they are much better than other purpose built gaming earbuds and headsets they have used previously. I looked around for a while at a decent pair of wired earbuds and settled on these as well priced, not breaking the bank, and having decent standards. Would buy again - they aren't going to be the best earbuds in the world for any audiophiles but for most purposes they are a great option.

Need to be tweaked if you listen to electric guitar based music
These headphones are good, but you are going to need to make some adjustments on your equaliser for them to sound correct if you listen to guitar based music. The bass and high end are turned up too much so the mid range is lost. They feel like they've been designed out of the box for dance music. It's a fairly simple fix. Just slightly boost the mid ranges on your equaliser and slightly turn down the bass and high frequency and it will get tracks sounding as they are supposed to.

Quite expensive for not being the best quality. But anti tangle which is always good

Don't buy
Not a very good product. Silicon buds come off very easily and pods are made of two separate cups that also easily come apart. Definitely not worth the money.

Poor quality, ear piece split in half, stopped working
These broke apart at the ear piece, just separated into 2 pieces. Less than a year old and not used often. Very disappointed, money down the drain

Tengo poco con ellos y no han pasado por la prueba del tiempo, entonces no puedo hablar de esa parte. En cuanto a audio, suenan muy claro, reproducen todos los sonidos con nitidez, le falta un poco de cuerpo/punch al bajo pero siguen reproduciendo correctamente esos sonidos. Se compartan bien en diferentes géneros, a diferencia de otros audífonos que priorizan bajos sobre otros elementos y terminan por ser "especializados" para música electrónica básica, descuidando la experiencia de escuchar otro tipo de música. En cuanto a relación calidad-precio, los compré por la marca, no tengo suficientes comparativas con audífonos de la misma gama para hablar de este factor, pero están bonitos y tienen mejor feel que otros más baratos. Los recomiendo aunque podría haber mejores opciones, sólo que no las conozco.

They sound good but are very uncomfortable for sleeping. I use ear buds to sleep to drown out the annoying snoring coming from my husband's side of the bed. I thought I would try out these Senheiser CX 300S ear buds because they were not too much more than the JBL T290 ear buds I was replacing (for the third time in 4 months making them much cheaper if they actually lasted). I paid $16.99 for each pair of the JBL's and the Senheisers were like $35 so it seemed like a good choice. They do seem durable with a metal casing (which is probably why they are uncomfortable for sleeping). They do sound a little richer than the JBL's which would have made them so much better for sleeping. I am keeping them to wear for streaming or to listen to music during the day.

Bester Kopfhörer den ich jemals hatte als kabelgebunden. Ist eben Sennheiser

Bonjour, J'ai acheté ces écouteurs Sennheiser CX 300S pour une écoute filaire donc et j'en suis pleinnement satisfait : bonne qualité d'écoute, attention à bien choisir la bonne taille d'embouts silicone et de bien enfoncer l'embout dans l'oreille : sinon mauvaise qualité de son et pas bien isolé des bruits extérieurs.

Amazing earbuds. The sound portfolio is excellent and I would highly recommend getting a pair of these.
