The 1More Sonoflow are over-ear headphones with good noise isolation, better battery life, and support for the LDAC codec, which is great for high-quality audio streaming; they're also suitable for air travel due to their noise isolation and comfort. On the other hand, the Grado GT220 are more portable stemless earbuds, provide a slightly better overall sound quality, and have wireless charging, making them convenient for charging on the go. If cost is a significant factor for you, the 1More Sonoflow is the less expensive choice, but if you prefer a more premium sound and the convenience of wireless charging, the Grado GT220 might justify the extra cost.

"The SonoFlow is cheap and fun, without going too far into being overly warm or annoyingly grating, or sharp sounding. The ANC features are lovely with strong app integration and excellent battery life."
