If top-notch sound quality is your priority and you prefer an open-back design that provides a more natural and spacious soundstage, you should consider the Focal Elex, but keep in mind that it lacks wireless connectivity and noise isolation, making it less versatile for commuting or noisy environments. However, the Sennheiser HD 350BT offers a closed-back design with better noise isolation and wireless convenience, which makes it suitable for on-the-go use, and also features a longer battery life and integrated microphone, making it more practical for calls and meetings. Consider the Focal Elex if prioritizing high-fidelity audio in quiet settings, or the Sennheiser HD 350BT if needing versatility with good sound quality. Give Feedback
