The Razer Kraken V3 headphones, being over-ear and closed-back, provide a more immersive sound but are bulkier and less portable than the Sennheiser CX300S earbuds. The Krakens are better for gaming and TV due to their good sound and mic quality but are not ideal for exercise or travel due to their size and lack of active noise cancelling. The Sennheiser earbuds are more suited for travel and exercise, given their smaller size, good noise isolation, and light weight, but may not provide the same level of sound quality for gaming or TV. Neither option supports wireless connectivity, so you'll be tethered to your device, and battery life is not a concern. If you're on a tighter budget and prioritize portability and exercise use, the Sennheiser CX300S could be more appropriate, while the Razer Kraken V3 could be the right choice if you're focusing on home gaming and entertainment.

Soundguys
Sam Smart | November 2022
"This Razer Kraken V3 is a great headset for gamers who want comfort, surround sound, and software customization for a reasonable price. It's primarily a headset for PC gamers since THX Spatial audio is only supported on Windows. If you want something more multifaceted for multiple systems, this won't be an ideal headset for you. Luckily, there are plenty of competent Kraken V3 alternatives available to you."

Carroll Moore | April 2019
"Sennheiser offers impressive bang for your buck when it comes to the CX 300S. Built like a tank and sounding surprisingly good for such a budget-minded earphone, the CX 300S out-classes many of its would-be competitors. Functional but beautiful, it’s the perfect in-ear listening solution for anyone who wants to hear everything and look good doing it."
