If you prioritize portability and use during exercise, the JBL Live Flex 3 earbuds are a premium option with sweat and dustproof features, a secure fit for active use, and they're lighter. They offer very good sound for music and are optimized for both Android and Apple devices with additional app control customization. However, they're not ideal for gaming or TV due to poor scores in these areas. Conversely, the Sennheiser HD 250BT headphones offer very good audio quality and are much less expensive, with excellent build quality and very good gaming and TV scores, but they are bulkier, less portable, and not suited for exercise or use in noisy environments. If you're looking for versatile use including gaming and watching TV without breaking the bank, Sennheiser is the better choice. Give Feedback

"As a lightweight, robust audio provider with a long battery life, the Sennheiser HD 250BT offer a lot for their price: very good Bluetooth codecs, an app connection and an extremely understated design. These headphones may not be among the most comfortable, but they deliver adequate sound – without overdriving or distortion."
