If portability and convenience are a top priority for you, the Soundcore Space A40 earbuds, with their wireless design and active noise cancellation feature, would be the better choice. However, if your focus is on sound quality and comfort for extended listening sessions, then the Sennheiser HD 400S headphones, known for their superior audio fidelity and comfort, could be more suitable, although they are wired and lack noise cancellation. The Soundcore Space A40 also offers a more feature-rich experience with touch controls and a microphone for calls, which may justify the higher price compared to the Sennheiser HD 400S. Give Feedback

"Sennheiser has done it again. The HD 400S performs well beyond its price range and is one of the better budget model headphones I’ve tried. It has very few bells and whistles and offers a simple means of listening that still delivers amazing clarity and quality. If you need a good first pair of headphones or need something that you can take out of the house, then the HD 400S is definitely for you."

"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."
