iQOO TWS 1i

Manufacturer: iQOO

The iQOO TWS 1i are true wireless in-ear earbuds designed for everyday use without the hassle of cables. They carry an IP54 ingress protection rating, making them resistant to sweat and light moisture, which suits active listening sessions well. A carrying case is included along with voice prompts and a find-device feature, rounding out a practical set of conveniences for daily use.

Connectivity is handled through Bluetooth 5.3 with a maximum range of 10 meters and an audio latency of 55 ms, while USB Type-C handles wired charging with fast charging support. The earbuds deliver up to 10 hours of playback on their 49 mAh cells, and the 513 mAh charging case extends total listening time to 35 hours. Sound is driven by a 10 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz, and a noise-canceling microphone is built in for calls, complemented by passive noise isolation.

Pros
  • Total battery life of 35 hours between the earbuds and charging case makes extended use practical without frequent recharging
  • Fast charging support helps reduce downtime when the battery runs low
  • IP54 rating provides reliable sweat resistance, making the earbuds suitable for workouts
  • A find-device feature adds a useful safeguard against misplacing the earbuds
  • Includes a travel bag for convenient storage and portability
  • Noise-canceling microphone helps deliver clearer voice quality during calls
Cons
  • No active noise cancellation, so audio isolation depends entirely on the physical in-ear seal
  • Wireless charging is not supported, requiring a cable every time the case needs a top-up
  • No fast pairing or NFC pairing, which adds a small friction to the initial setup process
  • None of the high-quality audio codecs such as LDAC, LDHC, AAC, or any aptX variant are supported
  • In/on-ear detection is absent, meaning playback does not pause automatically when an earbud is removed
Who is this for?

These earbuds are a practical fit for users who lead an active lifestyle, as the IP54 sweat resistance makes them dependable during workouts or outdoor use. The 35-hour total battery life between the earbuds and case suits those who need consistent listening throughout a busy day without worrying about recharging frequently. Users who regularly take calls on the go will also benefit from the noise-canceling microphone and mute function, which together support clear and manageable voice communication.

Who is this NOT for?

Users who prioritize deep immersive listening will find the absence of active noise cancellation limiting, as audio isolation relies solely on the physical in-ear seal. Audiophiles or those who demand high-resolution audio streaming will be underserved, given that none of the advanced codecs such as LDAC, LDHC, or any aptX variant are supported. Additionally, those who prefer a hands-free, seamless setup experience may find the lack of fast pairing and NFC pairing a minor but recurring inconvenience.
