Our Verdict
JBL Tune Flex True Wireless
JBL Tune Buds True Wireless
The JBL Tune Buds True Wireless are better in-ears for most purposes than the JBL Tune Flex True Wireless. While both pairs are equipped with ANC and have similarly flat mid-ranges that represent a variety of audio content well, the Tune Buds have a longer continuous battery life and a better noise isolation performance, making them a better choice for commuting. They also feature multi-device pairing, which is great if you want to connect multiple devices to them while working from home or at the office. However, some users may prefer the Tune Flex's stem design and that they come with both 'open' and 'sealing' ear tips, which allows you to choose between a passively isolating seal and one that lets in some ambient noise.
