The Ugreen HiTune Max5c feature an over-ear fit and a foldable design, making them reasonably convenient to store and transport, though no travel bag is included. They weigh 260 g and come with a 1-metre detachable cable, giving users the option to switch between wired and wireless use. The headphones have a closed-back construction with stereo speakers, but carry no water resistance rating and the cable is not tangle-free.
The Ugreen HiTune Max5c are equipped with 40 mm driver units and cover a frequency range of 20 Hz to 40,000 Hz, with an impedance of 32 Ohms. They support both active noise cancellation and passive noise reduction, giving users two layers of sound isolation, and also feature spatial audio support. The drivers do not use a neodymium magnet.
The Ugreen HiTune Max5c house a 600 mAh rechargeable battery that delivers up to 75 hours of playback, or 45 hours when active noise cancellation is enabled. The battery is not removable and wireless charging is not supported, but the headphones charge fully in just 1.5 hours via USB-C. A battery level indicator is also included, so users can keep track of remaining charge at a glance.
The Ugreen HiTune Max5c support both wireless and wired connectivity, using Bluetooth 5.4 with a maximum range of 10 metres and an audio latency of 60 ms. Codec support covers LDAC and AAC, while aptX, aptX Adaptive, aptX HD, aptX Low Latency, aptX Lossless, and LDHC are not supported. Fast pairing and NFC pairing are also absent, so connections are established through the standard Bluetooth pairing process.
The Ugreen HiTune Max5c can be used as a headset and feature a 5-microphone array with noise cancellation and a mute function, making them suitable for calls and voice communication. Controls are handled via an on-device panel, with no in-line control option on the cable. Ambient sound mode is included for environmental awareness, though the headphones lack in/on-ear detection for automatic playback pausing. Multipoint connectivity supports simultaneous pairing with up to two devices, and the headphones come with a 2-year warranty.
