If you prefer wireless convenience, the JBL Live Flex 3 earbuds are a better choice, especially for exercise, as they are sweatproof, have a secure fit, and offer very good sound quality along with active noise cancelling. They also have a smart charging case with an LED touch display for easy controls. However, if audio quality is your top priority and you're mostly listening in quiet environments or at home, the Sennheiser HD600 headphones, while larger and wired, provide excellent sound quality and a very good soundstage for an immersive experience, but they lack low-latency features making them less suitable for gaming and TV. The Sennheiser headphones are also not ideal for calls, as their mic quality is poor, while the JBL earbuds perform better in that area. Give Feedback
