If you prioritize portability and use during exercise, the JBL Live Flex 3 earbuds with their stem design and sweatproof certification may be more suited, and they also have a secure fit for active movement. However, if you're looking for a rich audio experience and you often participate in calls or meetings, the Sennheiser Accentum Plus headphones offer excellent microphone quality and superior comfort for prolonged use. The Sennheiser's also support aptX Adaptive codec for better sound quality over Bluetooth and active noise cancelling for quieter environments, beneficial for air travel. But if you need a longer battery life on a single charge, especially for extended periods away from power sources, the JBL offers that. Choose the Sennheiser's for extensive features and sound quality or the JBL's for an active lifestyle and convenience. Give Feedback
