Nu Republic Cyberstud X8

Manufacturer: Nu Republic

The Nu Republic Cyberstud X8 are true wireless in-ear earbuds designed for everyday wireless listening without the hassle of cables or a neckband. They include a travel bag in the box and support use as a headset, making them a practical option for both music and calls. Voice prompts and a mute function are built in, and the earbuds can be controlled directly via an on-device control panel.

On the technical side, the Cyberstud X8 use a 13 mm driver paired with a neodymium magnet and cover a frequency range of 20 Hz to 20,000 Hz.

  • No water resistance rating, making the earbuds unsuitable for use in wet conditions
  • Wireless charging is not supported, requiring a cable for every recharge

Who is this for?

The Cyberstud X8 is a good fit for everyday wireless listeners who prioritize long total battery life, since the combination of 7 hours on the earbuds and 49 hours from the charging case suits full workdays or travel without constant recharging. Users who frequently take calls will appreciate the noise-canceling microphone paired with the mute function and headset capability, making these earbuds practical for remote work or commuting. The included travel bag and USB Type-C charging also appeal to users who want a tidy, low-maintenance setup for on-the-go use.

Who is this NOT for?

Users who require active noise cancellation for focused listening in loud environments, such as open offices, flights, or busy commutes, will find this product lacking, as only passive isolation is available. Those who engage in sports or high-movement activities may find the earbuds less reliable without wingtips and with no water or sweat resistance to speak of. Additionally, audiophiles or users who rely on high-fidelity wireless codecs like LDAC, aptX, or AAC for elevated audio quality will find the connectivity options here too limited for their needs.

Final Verdict
