If you're looking for better overall sound quality, the Soundcore Space A40 earbuds have a slight edge. However, for phone calls and meetings, the Sennheiser 450BT headphones offer better microphone quality, which may be important if communication clarity is a priority. For gaming and watching TV, the Sennheiser 450BT is superior thanks to their low latency feature, providing a more in-sync audio experience. Both offer active noise cancelling for uninterrupted listening, but for long battery life and the convenience of wireless charging, the Soundcore Space A40 stands out. The Sennheisers are foldable for portability, whereas the Soundcores, being earbuds, are naturally more compact. Lastly, if exercising with your audio gear is important, the Soundcore earbuds are both sweatproof and offer a more secure fit during physical activity. Give Feedback

"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise canceling is good and sound quality is great—quite rare at this price point. Like any product, this headset isn’t without its faults."

"The Anker Soundcore Space A40 is an excellent deal if you want affordable noise canceling earbuds with great sound. The baseline frequency response is enjoyable, and the many EQ presets to choose from plus the ability to customize your sound profile makes it good for pretty much anyone. The noise canceling is quite good, and the many ear tips to choose from ensure a good fit for the noise canceling and isolation to do its job."
