SonoFlow-Pro HQ51
With 40mm diamond-like carbon drivers tuned by Grammy winner Luca and LDAC for Hi-Res wireless audio, these headphones deliver detailed sound and up to 100 hours of battery life. Hybrid QuietMax noise cancellation and a lightweight 246-gram design ensure all-day comfort and solid quieting on the go. Best for commuters and students who prioritize marathon battery life and high-resolution sound for music and gaming, but less suited for frequent call handling.
