On the fundamentals, these two earbuds are well-matched: both offer active noise cancellation, passive noise reduction, and an identical low-end floor of 20 Hz. The shared ANC and passive isolation combination means neither product is compromising on noise management at this price tier.
The divergence emerges in two notable areas. The Soundpeats C30 pairs a slightly larger 12 mm driver (vs. the R60i′s 11 mm) with a dramatically extended high-frequency ceiling of 40,000 Hz, compared to the R60i′s standard 20,000 Hz. The larger driver can theoretically move more air for a fuller low-end, and the extended frequency range — often marketed as ″hi-res audio″ — matters for listeners using high-resolution audio sources, though human hearing rarely exceeds 20 kHz in practice. The Anker Soundcore R60i, on the other hand, supports spatial audio, which the C30 lacks entirely. Spatial audio creates a simulated three-dimensional soundstage — a tangible, perceptible enhancement for movies, gaming, and certain music genres.
The edge here depends on listening priorities. The C30 is better positioned for audiophile-leaning users who value extended frequency response and a larger driver, while the R60i offers a more immersive, dimensionally richer experience through spatial audio support. Neither has a universal advantage, but for everyday mixed-use listening, spatial audio tends to have a broader real-world impact than an ultrasonic frequency extension most ears cannot detect.
