Verdict

The Phaz P4 is a wireless over-ear headphone featuring 40mm neodymium drivers designed to deliver a balanced frequency range of approximately 18Hz to 22,000Hz. A standout characteristic is its 1600mAh rechargeable battery, which supports active noise cancellation (ANC) and includes a unique integrated power bank feature for charging mobile devices via a USB port. Its lightweight carbon fibre construction, memory foam ear pads, and foldable design provide significant portability and comfort. Main pros include the ability to share audio through dual 3.5mm jacks, high-capacity battery life, and a detachable cable for improved durability. However, potential cons include a lack of modern high-definition Bluetooth codecs like aptX or LDAC in older versions, and a build that may feel stiff compared to all-metal alternatives.
