After weeks of intensive testing, I’m ready to share my in-depth review of the OnePlus Buds 3 (E509A) in Metallic Gray. These earbuds promise a compelling combination of deep bass, effective active noise cancellation (ANC), and impressive battery life. But do they deliver on these promises? Let’s dive in.

The OnePlus Buds 3 boasts several notable features. The dual dynamic drivers – a 10.4mm woofer and a 6mm tweeter – are designed to provide a balanced sound profile with punchy bass. OnePlus’s BassWave technology further enhances the low-end, while OnePlus Audio ID 2.0 allows for personalized audio tuning based on your hearing profile. Adaptive noise cancellation promises to effectively block out ambient noise, and AI Clear Call technology aims to improve call clarity, even in noisy environments. The earbuds also offer a claimed 44 hours of total battery life with the charging case.

Sound quality is generally excellent. The bass is indeed deep and impactful, without overwhelming the mids and highs. The separation between instruments is good, and the overall soundstage is surprisingly spacious for in-ear earbuds. OnePlus Audio ID 2.0 is a nice touch, allowing for a truly customized listening experience. The ANC is effective at reducing low-frequency sounds like engine noise and airplane hum, though higher-frequency sounds, like human voices, still penetrate somewhat. Call quality is consistently clear, even in moderately noisy environments. The 44-hour battery life claim holds true in my testing, which is impressive. Comfort is good for extended listening sessions; I wore them for several hours at a time without discomfort.

Pros:

• Excellent sound quality with deep bass
• Effective active noise cancellation
• Impressive battery life (44 hours)
• Comfortable fit
• Personalized audio tuning with OnePlus Audio ID 2.0
• Good call quality

Cons:

• ANC struggles with higher-frequency noises
• Touch controls could be more responsive

The OnePlus Buds 3 (E509A) offer a compelling package of features and performance. The sound quality, battery life, and ANC are all strong points. While the ANC isn’t perfect, it’s still effective enough for everyday use. The minor drawbacks, such as slightly less responsive touch controls, are easily overlooked considering the overall value proposition. If you’re looking for a pair of wireless earbuds with excellent sound, long battery life, and effective noise cancellation, the OnePlus Buds 3 are a solid choice. I highly recommend them.
