OnePlus Buds Pro 3

Manufacturer specification

Sennheiser HD 650

Manufacturer specification · The manual rates 10–41,000 Hz at −10 dB; Sennheiser's UK feature list quotes 12–41,000 Hz without a threshold.

Range endpoints need their stated threshold. They do not describe response flatness or prove better bass, detail or sound quality.

Manufacturer sensitivity and reference

OnePlus Buds Pro 397 ± 3 dB at 1 kHz (Input: -10 dB IEC711)

Sennheiser HD 650103 dB SPL at 1 kHz, 1 V rms

Sources

OnePlus Buds Pro 3

Manufacturer specification · Buds 4 names a 1 mW input but no frequency or test fixture. Buds Pro 3 names 1 kHz and the literal “Input: -10 dB IEC711” notation, without identifying that input in volts or milliwatts. These do not provide sensitivity on the same basis; do not convert or rank them.

Sennheiser HD 650

Manufacturer specification · Rated at 1 kHz with 1 V rms; not directly comparable with dB/mW ratings.

Keep the frequency and voltage or power reference attached. Sensitivity describes output for an input, not sound quality; dB/V and dB/mW are different measures.
