If you’re seeking earbuds for a versatile experience, including exercise and casual usage, and prefer something lightweight and suited for on-the-go calls, the JBL Tune Flex would serve you well, especially considering they have a Sweatproof certification and offer low latency for gaming and video. However, if you're looking for headphones that excel in noise isolation and have a much longer battery life for extended listening sessions, the Soundcore Space Q45 would be more suitable, with the added bonus of active noise cancelling and a foldable design for easier travel.

"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."

"The Anker Soundcore Space Q45 is a great pair of active noise canceling (ANC) headphones, and the $150 USD price tag only sweetens the deal. Unlike many mid-tier wireless headphones, the Q45 microphone system rejects quite a bit of background noise, making this a great work headset too."
