If you want a true active noise cancelling earbud with a low-latency ambient sound passthrough you can toggle with a tap, choose Samsung Galaxy Buds2; if you need marathon battery life, a bigger driver and app-based EQ control in a splash-resistant shell, choose XIAOMI Redmi Buds 6.
• Samsung Galaxy Buds2 — biggest strength: A complete two-way awareness system. Active Noise Cancellation shuts the world out, and a low-latency Ambient Sound mode lets it back in, all on a 10% smaller, lighter body with 3 microphones for calls.
• Samsung Galaxy Buds2 — biggest trade-off: It's listed as the International Version with no warranty and sold as a renewed unit, so you're buying a professionally inspected pre-owned product rather than a factory-sealed retail box.
• XIAOMI Redmi Buds 6 — biggest strength: Endurance and tuning flexibility. Up to 30 hours total with the case, a 14.2 mm dynamic driver, five EQ modes through the Xiaomi Earphone App and IPX4 splash resistance.
• XIAOMI Redmi Buds 6 — biggest trade-off: Its noise story is built around call clarity (2-mic beamforming with a DNN ENC algorithm and wind-noise filtering), not around blocking out your surroundings for music.
• Pick Samsung Galaxy Buds2 if you want ambient sound mode as a daily feature — hearing announcements, traffic or a barista while your music keeps playing.
• Pick XIAOMI Redmi Buds 6 if you want long listening sessions, deeper bass and app-controlled sound on a tighter budget.
The Galaxy Buds2 is the more complete "awareness" earbud of these two. Samsung pairs Active Noise Cancellation with a low-latency Ambient Sound mode, which means you can flip between shutting the world out and letting it back in without pulling the buds from your ears. That toggle is the whole point of this comparison, and it's the feature Samsung built the marketing around. The ambient mode is described as low latency, which matters in practice: when someone speaks to you, you want their voice to arrive now, not half a second after their lips move.
Physically, these are the smaller pick. Samsung says the Buds2 are 10% smaller and lighter than the Galaxy Buds+ — each bud is around 5 g — with a rounded, low-profile in-ear shape in a Graphite finish. For long wear, that lightness plus a rounded tip is the difference between "I forgot I had these in" and "I'm counting the minutes until I can take these out." The spec sheet lists a 7.5-hour average battery life per charge and 20 hours with the carrying case, a 2.5-hour charge time, Bluetooth 5.0, a 10-metre range, 16-ohm impedance, a dynamic driver and a 20 Hz–20,000 Hz frequency range.
Where it may not fit: this listing is the International Version, sold as a renewed product with a 90-day limited warranty and no manufacturer warranty. If you want a brand-new sealed box with full coverage, that's a real consideration. Also, the touch controls are convenient but demand a light touch — no physical buttons here.
Buy it if you want noise cancelling plus a genuine ambient sound mode, a compact fit and call clarity from 3 microphones. Skip it if you'd rather avoid renewed stock and want the longest possible battery.
The Redmi Buds 6 plays a different game: stamina, bass and app control. Xiaomi rates the single-charge life at up to 6 hours, stretching to 30 hours with the charging case — and the case itself carries a 475 mAh battery with a 2-hour charge time. That's the standout number here. For commuters, students or anyone who resents charging a case every other day, 30 hours is the spec that actually changes your routine.
The audio hardware is bigger too. A 14.2 mm dynamic driver, described with a better low-frequency response and higher sound pressure level, tuned by the Xiaomi Acoustic Laboratory, plus five EQ settings you switch in the Xiaomi Earphone App. If you like shaping your sound — more bass on the train, flatter for podcasts — that flexibility is genuinely useful. Bluetooth 5.4, a 10-metre range, 16-ohm impedance, 106 dB sensitivity, a 20 Hz–20,000 Hz range and 49 ms latency round out the wireless side.
Buy it if you want long battery life, big-driver bass, EQ control and splash resistance. Skip it if the ambient sound toggle is your top priority.
Side-by-Side: Which Should You Choose?
• Best for ambient sound mode → Samsung Galaxy Buds2. It's the only one of the two with a dedicated, low-latency Ambient Sound mode alongside Active Noise Cancellation.
• Best for battery life → XIAOMI Redmi Buds 6. Up to 30 hours with the case versus 20 hours on the Buds2.
• Best for bass and sound shaping → XIAOMI Redmi Buds 6. A 14.2 mm driver and five app EQ modes beat a single tuning.
• Best for a light, low-profile fit → Samsung Galaxy Buds2. Roughly 5 g per bud and a body 10% smaller and lighter than the Galaxy Buds+.
• Best for calls in windy places → XIAOMI Redmi Buds 6. Its mic design targets wind noise up to 4 m/s; the Buds2 leans on 3 microphones with noise reduction for voice clarity.
• Best for working out in light rain → XIAOMI Redmi Buds 6, thanks to IPX4 splash resistance.
• Best for a sealed, warrantied purchase → XIAOMI Redmi Buds 6, with a 1-year manufacturer warranty versus 90 days on the renewed Buds2.
• Best for lower latency on Bluetooth → XIAOMI Redmi Buds 6 lists 49 ms audio latency with Bluetooth 5.4, against Bluetooth 5.0 on the Buds2.
For the specific question of ambient sound, I'd buy the Samsung Galaxy Buds2. A dedicated low-latency Ambient Sound mode sitting next to Active Noise Cancellation is exactly what this feature is for, and the smaller, lighter fit makes it comfortable to keep in all day. The renewed, International Version listing and shorter warranty are the honest downsides. If ambient awareness isn't your priority and you want maximum battery, bigger bass and app EQ instead, I'd point you to the XIAOMI Redmi Buds 6. Check the current price on Amazon for both before deciding — the value gap swings the answer for a lot of buyers.
FAQ
what is ambient mode on earbuds
Ambient mode is a setting that uses the earbuds' microphones to pipe outside sound into your ears while you're listening to audio. It lets you hear traffic, announcements or a conversation without removing the buds. On the Galaxy Buds2 it's paired with Active Noise Cancellation, so you can switch between blocking the world out and letting it in.
It's the same idea under a different name: external microphones capture surrounding sound and play it through the drivers in real time. Samsung describes the Galaxy Buds2's version as low latency, which keeps voices in sync with what you see. The Redmi Buds 6 focuses its microphone processing on call clarity instead.
what is ambient mode in earbuds
Ambient mode is essentially a transparency feature — you stay aware of your surroundings without pausing your music. It's most useful when walking, cycling or ordering coffee. In my opinion, the Galaxy Buds2 is the stronger choice of these two for that specific use, since it's the one with a dedicated Ambient Sound mode.
The Redmi Buds 6. Xiaomi rates it at up to 6 hours per charge and 30 hours with the case, while the Galaxy Buds2 lists 7.5 hours per charge and 20 hours with its case. Per single charge the Buds2 lasts longer; across a full case cycle the Redmi Buds 6 wins.
