If budget is a primary concern, the JBL Tune Flex earbuds could be the right choice as they are significantly less expensive than the Sennheiser Momentum 4 headphones while offering a very good overall sound quality. However, if you prioritize comfort, build quality, and noise isolation, the Sennheiser Momentum 4 may justify their higher price. They also have superior battery life, active noise cancelling for quieter environments, and are optimized for a more immersive audio experience, making them suitable for extended listening sessions, air travel, or focused listening at home. For those who are active, the JBL Tune Flex have a low latency mode and are sweatproof certified, which is ideal for exercise. Both options support wireless use, but if a wired connection is preferable at times, only the Sennheiser offers that flexibility. 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."

"If you're looking for a slightly more affordable set of ANC headphones in comparison to the Bose or Sony offerings: the Sennheiser MOMENTUM 4 Wireless is not a bad way to go. While its ANC is technically behind the other top-tier headphones, its sound quality is ahead of the pack—as is its battery life. Not bad for $350 USD."
