Ask Agent About This Product

The biggest complaint about the original QuietComfort Ultra Earbuds? Call quality. People on the other end couldn't always hear you clearly, especially in noisy places. Bose fixed that with SpeechClarity on the 2nd Gen.

What It Actually Does

SpeechClarity is a smart filter for your voice. When you're on a call, the earbuds use AI to figure out what's your voice and what's background noise—then suppress the "everything else."

The tech behind it is impressive: eight microphones working together, plus bone conduction sensors that detect the vibrations of your actual speech. That combination helps the system know with confidence what's you talking versus what's a coffee shop or traffic.

Does It Work?

From user reports? Yes, significantly. People who upgraded specifically for better call quality say the difference is noticeable. Callers hear less background noise, voices come through clearer, and even wind is handled better (though strong wind still causes issues—that's just physics).

If you work from home and take video calls, or you're often on the phone in public spaces, this is a meaningful improvement.

Where It Shines

• Video calls with background noise in your house
• Phone calls at coffee shops or airports
• Walking outside on mildly windy days
• Any situation where the old earbuds made people say "you're breaking up"

Where It Still Struggles

No earbuds handle extreme wind perfectly. If it's really blowing, you're going to have issues regardless of how good the tech is. Also, Bluetooth has bandwidth limitations that affect voice quality on any wireless device.

The Bottom Line

If call quality was the one thing holding you back from the original model, SpeechClarity specifically addresses that complaint. Users who upgraded for this feature generally report it was worth it.
