Overview

The SoundPEATS Air4 Pro is a budget true-wireless earbud launched in September 2023. It features adaptive ANC, a 13 mm dynamic driver, Qualcomm QCC3071, multipoint, and aptX Lossless within Snapdragon Sound. The current representative US street price is 69.99 USD (see [2]). SoundPEATS’ US product page lists 26 hours total battery life in the hero copy but the spec table elsewhere shows 40 hours total; we treat 26 hours as the reliable figure and rely on third-party battery tests for single-charge life (see below). [1][2]

Scientific Validity

\[\Large \text{0.4}\]

• ANC (measured): Independent testing reports an A-weighted average cancellation of 9.73 dBA with strongest attenuation below 200 Hz. A per-frequency table (30 Hz–2 kHz) is published alongside methodology, allowing a transparent, numeric comparison. This is modest but credible performance for budget ANC. [2]
• Passive isolation: Average 10.53 dBA A-weighted isolation indicates a shallow seal; high-frequency leakage remains. [2]
• Battery (measured): With ANC on, aptX active, and ~70 % volume, single-charge playback is ~3 h 45 m; aligns with multiple consumer reviews noting ~4 h real-world. [7]
• Specs cross-check: Product pages confirm QCC3071, aptX Adaptive/Lossless, Bluetooth 5.3, IPX4, and 6-mic array; codec and chipset claims are consistent across sources. [1][3]

Takeaway: There are concrete, published numbers for ANC and isolation, and consistent vendor specs for codecs/chipset. The scientific picture is mixed: measurable ANC exists but is not class-leading; isolation and battery per charge are weak.

Technology Level

\[\Large \text{0.6}\]

QCC3071 with Snapdragon Sound and aptX Lossless is modern silicon for budget TWS. Adaptive ANC, multipoint, and a 6-mic beamforming array are standard 2023–2024 features. No distinctive in-house algorithms or novel acoustical architecture are evident beyond Qualcomm’s platform. [1][3]

Cost-Performance

\[\Large \text{1.0}\]

Target price (US): 69.99 USD.
Among options with equal or better user-facing functions and measured performance, we did not find a cheaper product as of the review date:

• EarFun Air Pro 4 (aptX Lossless/LDAC, stronger feature set): 89.99 USD MSRP. [4]
• Anker Soundcore Space A40 (better ANC/battery, LDAC; no aptX Lossless): 99.99 USD official. [5][6]

Because no cheaper equivalent-or-better alternative was identified, CP = 1.0 per rule.

Reliability & Support

\[\Large \text{0.6}\]

Standard 12-month warranty, IPX4 water resistance, and an app with EQ and mode control. Build and case are typical for the class. No long-term failure-rate data is available; firmware cadence is average for budget TWS. [1][3]

Rationality of Design Philosophy

\[\Large \text{0.7}\]

Prioritizing Snapdragon Sound (aptX Lossless) and multipoint at a low price is rational for Android users with compatible phones. The trade-offs are clear: modest ANC magnitude, shallow seal, and short per-charge endurance. The design choices target check-box modernity rather than pushing new acoustic performance boundaries. [1][2][3]

Advice

If you specifically want aptX Lossless on a budget and can live with ~4 hours per charge and modest ANC, Air4 Pro is a sensible buy at 69.99 USD. If you value longer battery life and stronger ANC, consider Soundcore Space A40 (official 99.99 USD) or if you want Lossless and LDAC together with a richer app, EarFun Air Pro 4 (89.99 USD).
