If sound quality is a priority, particularly for music and videos, the Sennheiser HD 350BT headphones offer superior audio performance. However, for portability, the Soundcore Space A40 earbuds are lighter and come with a case that provides additional battery life. For gamers, the Sennheiser's low-latency feature would be better, but if you're looking for features like active noise canceling and wireless charging, the Space A40 would be the one to choose. The Sennheisers don't have noise canceling but are more comfortable for longer wear, while the Soundcore's stemless design is sweatproof and suitable for exercising. Give Feedback

"Sennheiser nails just nearly everything about the Sennheiser HD 350BT headphones. Sound quality is excellent, and the high-quality Bluetooth codec support is a rarity at this price point. If you don’t care for high-tech features like automatic ear detection, you’ll be delighted with these portable headphones."

Sam Smart | May 2023
"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."
