If you're looking for wireless convenience and exercise suitability, the JBL Tune Flex with its Low Latency Mode, sweatproof certification, and active noise cancellation would be ideal. For gaming and calls, these may also be better due to their low latency and fair call quality. However, if you favor open-back design for a more natural sound and don't mind a wired connection, the Koss Porta Pro is a classic choice that excels in music listening and comfort, but lacks features such as sweatproofing and active noise cancellation, making them less suitable for exercise or noisy environments. Keep in mind that the JBL Tune Flex has app-based customization options which the Koss Porta Pro lacks, and the latter’s on-ear design can be less isolating than the in-ear JBL Tune Flex.

"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."

"It’s clear to see why these have been such a popular choice amongst listeners for nearly four decades. It’s a charming pair of headphones that delivers a truly enjoyable listening experience and one that I think punches well above its weight."
