Itel S9 Ultra specifications and in-depth review

Itel S9 Ultra

Manufacturer: Itel

The Itel S9 Ultra are true wireless earbuds designed for everyday use without the hassle of cables. They carry an IPX5 water resistance rating, making them reasonably durable against sweat and light splashes. The case includes a travel bag and supports USB Type-C charging, while fast charging support means less time waiting between listening sessions.

On the technical side, the S9 Ultra uses a 10 mm driver unit with a frequency response spanning 20 Hz to 20,000 Hz and passive noise reduction for basic sound isolation. Bluetooth 5.3 handles wireless connectivity up to 10 meters. The earbuds carry a 28 mAh battery for up to 6 hours of playback, backed by a 400 mAh charging case that extends total usage to around 24 hours. A noise-canceling microphone, mute function, voice prompts, and on-device controls round out the feature set, and the product comes with a one-year warranty.

Pros
  • IPX5 water resistance makes the earbuds suitable for use during workouts or in light rain
  • Bluetooth 5.3 provides a relatively stable and modern wireless connection
  • The 400 mAh charging case extends total listening time to 24 hours, reducing how often the case itself needs recharging
  • Fast charging support helps reduce downtime between uses
  • A noise-canceling microphone improves call clarity by filtering out background noise
  • A travel bag is included in the box, offering a convenient way to carry and store the earbuds
Cons
  • No active noise cancellation, so listening in loud environments depends entirely on passive isolation
  • The 10-meter Bluetooth range is limited compared to what many users might expect for wireless earbuds
  • No advanced audio codecs such as LDAC, aptX, or AAC are supported, restricting high-quality audio streaming options
  • Wireless charging is not supported, requiring a wired connection every time the case needs to be charged
  • There is no find device feature, making it harder to locate misplaced earbuds
  • In-ear detection for automatic playback pause is absent, requiring manual interaction to pause audio
Who is this for?

The Itel S9 Ultra is a good fit for everyday listeners who want a cable-free, truly wireless experience without the complexity of advanced audio settings. Its IPX5 water resistance makes it practical for gym sessions, commutes, or outdoor use where exposure to sweat and light moisture is likely. The included noise-canceling microphone and headset capability also suit users who frequently take calls on the go, while the 24-hour total battery life with the case works well for those who need reliable all-day usage without constant recharging.

Who is this NOT for?

Users who prioritize high-fidelity audio will find this model limiting, as it lacks support for advanced codecs such as LDAC, aptX, or AAC, which are typically needed for higher-quality wireless audio streaming. It is also not well suited for use in consistently loud or noisy environments, since there is no active noise cancellation and only passive isolation is available. Additionally, those who rely on smart convenience features such as automatic ear detection, ambient sound passthrough, or a find device function will find those capabilities absent here.
