If you highly value wireless convenience, better portability, and active noise-canceling for a quieter listening experience, especially when exercising or traveling, the JBL Live Flex 3 earbuds would be more suitable despite their higher cost. However, they provide poor performance for TV, video, and gaming due to latency issues. In contrast, if gaming and durability are your top priorities and you prefer a fuller soundstage with over-ear comfort, the Razer Kraken headphones offer excellent mic quality and low latency ideal for this purpose at a more budget-friendly price, but at the expense of portability and with no wireless functionality.

PC Gamer
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."
