Verdict

The Bang & Olufsen Beoplay H9i is a luxury wireless over-ear headphone featuring 40mm electrodynamic drivers with a frequency range of 20 Hz to 22,000 Hz and Bluetooth 4.2 connectivity. Known for its premium build quality, it utilizes cowhide leather on the headband, soft lambskin with memory foam for the ear pads, and anodized aluminum for the frame. Main characteristics include advanced hybrid active noise cancellation (ANC), a proximity sensor for automatic play/pause, and a 23-hour battery life (reduced to 18 hours with ANC and Bluetooth active). Key pros include its exceptional design, effective transparency mode, and a refined sound signature with a dedicated bass port for powerful yet controlled low-end. However, some users note cons such as intermittent proximity sensor performance, a touch interface that can be finicky to master, and a high retail price compared to competitors.
