The Focal Bathys excel in sound quality, are versatile with both wireless and wired options, have active noise canceling for quiet listening, and have more modern features like app customization and a decent battery life for portable usage. They are ideal if you prioritize noise isolation, high-quality audio for various media, and the flexibility of wireless use despite their higher price. In contrast, the Sennheiser HD600 headphones, while not wireless, offer impressive sound quality for their price, better suitability for quiet environments due to their open-back design, and are a strong choice if you mostly listen to music at home or in studios where isolation isn’t a concern. They lack modern features like a built-in mic and active noise canceling, but their durability and sound quality make them a classic choice for audiophiles on a budget. Give Feedback
