The HifiMan Sundara will provide you with superior overall sound quality, outstanding soundstage for an immersive experience, and high comfort for extended listening. However, they lack a built-in microphone and controls, and are not wireless, making them less versatile for activities like calls or exercising. Their open-back design also means they won't isolate noise well, so they're not ideal for noisy environments or air travel. On the other hand, the Sennheiser 450BT offers good sound quality with convenient features like wireless connectivity, active noise cancelling, foldability for portability, and a substantial battery life. The Sennheiser is more suitable for varied use, including travel, exercise, and video, and it's also more affordable. Give Feedback
