stemmed earbuds with a dynamic driver that perform well for music, gaming, and exercise, the JBL Tune Flex would suit you well, but the mic quality is poor. The Soundcore Space A40, also with a dynamic driver, boasts excellent noise isolation and has a longer battery life with wireless charging, making them ideal for air travel; however, they are not the best option for gaming or watching TV. Both have app customization, but if you value mic quality or will be making calls often, the Soundcore's mic is also rated as fair. Choose the JBL Tune Flex for a versatile experience or the Soundcore Space A40 for quieter environments and longer usage without charging. Give Feedback

"JBL is offering a similar design and arguably better resolution than the more expensive AirPods 3rd Generation. Add to that a comfortable and versatile fit, an equalizer and pretty decent ANC, and you’ve got a quality wireless earphone. I would have loved longer battery life and more crystal calls, but for the price, you can’t complain. A solid deal overall."

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."
