Model overview based on user reviews
The Sennheiser CX 300 II headphones are praised for their excellent sound quality, particularly in the highs and mids, with a rich bass that can be enhanced with an equalizer. Users appreciate their comfortable fit and effective noise isolation, making them suitable for both indoor and outdoor use. However, there are concerns about the durability of the cable, with several users experiencing issues with the plug and wire contacts over time. The headphones are considered a great value for money, though buyers are advised to ensure they purchase the original product due to the prevalence of counterfeits. Despite some durability issues, many users find them to be a reliable choice for everyday listening.

This is probably one of the best headphones in the world in their price category. There are a lot of positive reviews and for good reason. I listened to a lot of headphones including sony, jbl and even marshall mode eq that cost almost $ 100. Compared to these, they were not even close. And here it’s not even about the pricing policy. The only minus who is going to buy them is the very quality of the cord, it’s too thin at the branching points and the headphones themselves don’t have any thickening from the kink. Therefore, if you pull them with a dope or catch them, they’ll get fucked and it’s really So)) Bass sound quality and vacuum are on top. There are no equal!) Cord quality use Sennheiser CX 300 II less than month |
If you need headphones and don’t have a lot of money, then definitely these -sound is super -design is attractive (as for me) -noise isolation is okay (comfortable to travel in a minibus or bus) -cable length is more than sufficient after 3 years they began to play a little quietly, but it’s not so noticeable  Egor: use Sennheiser CX 300 II more than year |
I would choose a different model, the jack (plug) is disgusting, after a month it began to die. Before this there was the same model, the plug died in the same way, but it lived longer. The sound is not bad, but still not satisfying, the highs/upper mids are too much. Horrible, disgusting plug.  Iosif Kacman: use Sennheiser CX 300 II few months |
