The Bose QuietComfort Ultra Earbuds offer superior sound quality, active noise cancelling, and are optimized for both Android and Apple devices. They are portable and sweatproof, making them great for exercise, travel, and outdoor use. Their battery life is 6.5 hours, with an additional 21 hours from the case. On the other hand, the Razer Kraken provides a good microphone, virtual surround capabilities, and a durable design suitable for gaming. However, they are wired headphones with less portability and no active noise cancellation. Choose Bose for a premium, versatile wireless experience, or Razer for gaming-focused needs and budget-friendliness. Give Feedback

"Bose put the time in to fix the major issues with the previous earbuds, and the Bose QuietComfort Ultra Earbuds are very befitting of its price point. While you might be tempted to save a few bucks and go with the Bose QuietComfort Earbuds II on sale, fight the urge. There are enough upgrades here to justify the newer model."

"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."
