If you're focused on budget and exercise use, the JBL Live Flex 3 is a solid choice with good noise isolation and features like the Smart Charging Case. However, if sound quality for gaming and TV is a priority and you'd like higher-end features such as aptX Lossless codec, the Sennheiser Momentum True Wireless 4 offers excellent gaming audio and active noise cancelling. Keep in mind, the JBL has better battery life, is sweatproof, and optimized for exercise, while the Sennheiser is known for its Snapdragon Sound Technology and Bluetooth LE support, making it a more versatile pair for different uses.

What HiFi
Andy Madden | January 2024
"It’s fair to say our brief time with the Sennheiser Momentum True Wireless 4 was a generally positive one. Comfort levels seem similar to what we have experienced before and the general flavour of sound was to our liking although we need to get a pair in to test and put up against the big rivals at the money from Bose and Sony. It could be an interesting contest."
