The HyperX Cloud II is a gaming-focused headset with a closed-back design, providing good sound isolation, and it comes with a boom microphone that's detachable. They are wired, which eliminates latency concerns for gaming and TV. This makes them well-suited for immersive gaming experiences and calls where microphone quality is important. The Sennheiser HD 350BT, on the other hand, is a wireless option with Bluetooth support, including AptX Low Latency, offering greater freedom of movement and convenience for listening to music or podcasts on the go. However, they might not be as suitable for activities that require low latency, like gaming or watching videos. The Sennheisers also have an integrated microphone, which is less conspicuous than a boom mic but might not offer the same voice quality. The choice depends on whether you prioritize wireless convenience and music listening (Sennheiser) or gaming performance with a superior mic (HyperX). Give Feedback

"Sennheiser nails just nearly everything about the Sennheiser HD 350BT headphones. Sound quality is excellent, and the high-quality Bluetooth codec support is a rarity at this price point. If you don’t care for high-tech features like automatic ear detection, you’ll be delighted with these portable headphones."
