If you prioritize sound quality and an expansive soundstage for a more immersive music experience, and don't mind the lack of wireless capabilities, the HifiMan Sundara would be a better choice. Note that they have an open design which doesn't isolate sound well, making them less suitable for noisy environments or when privacy is needed. On the other hand, if you're looking for versatility, including the convenience of wireless listening, and a good option for calls and gaming with low latency and a microphone, the Sennheiser HD 350BT would suit you better. They are also more portable, with a foldable design and lighter weight. Keep in mind the Sennheiser has active controls and a significantly longer battery life for extended use without charging, whereas the Sundara lacks these features due to being wired. The Sundara is priced higher, reflecting its premium positioning in the market. Give Feedback
