If you're looking for headphones that are ideal for listening to music with a broad soundstage, the Koss Porta Pro would suit you, but their open design means they're not good for noisy environments as they provide minimal noise isolation. They're not wireless, which makes them less convenient for on-the-go use compared to the Soundcore Space A40, which offers great portability, a stable Bluetooth connection, and active noise cancelling to block out ambient sounds. The Soundcore earbuds are also more suitable for air travel and have features like wireless charging and app-based equalizer settings. However, their sound quality for music is slightly less immersive compared to the Koss Porta Pro. The Koss is less expensive, but if the added features of the Soundcore are vital to you, they might be worth the higher price. Give Feedback

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."
