Xiaomi has laid claim to a debut for the advanced LHDC 5.0 codec in TWS earphones with its new Buds 4. They are also rated for "intelligent" active noise cancellation (ANC), Independent Spatial Audio and up to 30 hours of battery life. They are available to order from now, albeit in China only, at a lower starting price than their Pro counterparts.

The Xiaomi Buds 4 have launched as the vanilla variant of their series; however, they have a surprisingly large amount in common with the pre-existing Pros. This includes an AirPod-like design; Bluetooth 5.3; their maker's Independent Spatial Audio; an IP54 ingress-protection rating and a Hi-Res Audio Wireless certification.

Then again, the Buds 4 are semi-in-ear, which means they lack optional ear-tips. Xiaomi asserts that their design and "balance" will keep them in the wearer's ear nonetheless. They also still support ANC, albeit with no mention of the 48dB exclusion rating of their Pro siblings.

However, they have launched with a newer form of LHDC (5.0, or LHDC V) compared to the higher-end earbuds. Xiaomi notes that this codec is capable of delivering "6x" CD quality with a sampling rate of up to 192kHz.

The Buds 4 are also rated for "HiFi Quality" sound thanks to their 11mm drivers augmented with a graphene diaphragm and a "dual-magnet" system for potentially enhanced bass.

The new Xiaomi Buds can last for an estimated 6 hours between charges, or find up to 24 more in their battery case, which supports USB type-C but not wireless charging.

Both buds and case are finished in two-tone choices of Moon Shadow Black, Salt Lake White or Wilderness Green, available at 699 yuan (~US$100) through channels such as Xiaomi's own Chinese web-store from now.
