Verdict

The Phiaton 900 Legacy Plus is a high-performance over-ear wireless headphone featuring advanced digital hybrid active noise cancellation (ANC) and custom 40mm double-layer drivers that support aptX HD, aptX Adaptive, and AAC codecs for 24-bit high-resolution audio. Key characteristics include Bluetooth 5.1 with multipoint connection, smart play/pause sensors, and intuitive touch controls housed within an elegant carbon fiber pattern shell. The headphones boast an impressive 43-hour battery life with ANC enabled, supported by a quick-charge feature that provides 4 hours of playback from a 10-minute charge, alongside CVC dual microphones for clear call quality. Main pros include its best-in-class battery longevity, effective noise reduction up to 98%, and a lightweight 256g foldable design that prioritizes comfort with memory foam earpads. Available cons noted by some users include occasional bass boominess that can crowd the midrange and a frame that may feel bulky or uncomfortable for those with larger ears or glasses during extended listening sessions.
