If gaming is your priority, the Razer Kraken with its lower latency and a built-in microphone is ideal for clear in-game communication and timely audio feedback. However, for everyday music listening, the Sennheiser HD 350BT offers superior sound quality and comfort for long sessions with Bluetooth connectivity that the Kraken lacks, but be aware of potential lag when watching videos or playing games due to higher wireless latency. Both have solid build quality, but if you need portability, Sennheiser's foldable design is more travel-friendly. Make your choice based on whether your focus is gaming or audio fidelity and convenience on the go. Give Feedback

Rob Dwiar | March 2019
"Generally the Kraken is a very comfortable headset and there’s nothing that really identifies it as anything else. All in, the Kraken performed exactly as I’d expect a premium, designated gaming headset to perform: performing well in game audio, though not quite with the same quality of those headsets further up the price scale."

"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."
