How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the best ambient sound mode earbuds for everyday awareness and calls, choose JBL Tour Pro+ TWS; if you need workout earbuds that lock into your ears and survive sweat and rain, choose Anker soundcore Sport X20.
• JBL Tour Pro+ TWS — biggest strength: Smart Ambient technology with Adaptive Noise Cancelling, so you can stay alert to the world around you or hear a conversation clearly at the touch of a button (or through the JBL app).
• JBL Tour Pro+ TWS — biggest trade-off: It is a lifestyle design, not a rugged one. There is no waterproof or dustproof rating in the spec sheet, so heavy sweat and rain are a real concern.
• Anker soundcore Sport X20 — biggest strength: Adjustable ear hooks with up to 30 degrees of rotation and 4mm of extension, plus an IP68 waterproof, sweatproof and dustproof build.
• Anker soundcore Sport X20 — biggest trade-off: Its ambient story is thinner. The specs emphasize noise cancelling and focus, not a named transparency mode for staying aware of your surroundings.
• Who each pick is for: JBL for commuters, office workers and call-heavy users who want ambient sound mode and voice control; Sport X20 for gym-goers, runners and anyone whose earbuds fall out.
The JBL Tour Pro+ TWS is built around one idea: keep you connected to your music without cutting you off from the world. That is where Smart Ambient Technology comes in. Flip it on with a button press or through the JBL app, and you can hear a colleague at your desk, a platform announcement, or a barista calling your name without pulling an earbud out. Paired with Adaptive Noise Cancelling that uses internal and external mics, this is one of the more complete awareness setups you can get in a true wireless pair. For anyone asking what ambient mode on earbuds actually does, this is the answer in practice — it pipes the outside world back in on purpose.
Sound is handled by 6.8mm dynamic drivers tuned for JBL Pro Sound, which the brand describes as rich, punchy bass up through thrilling top notes. Calls get real attention too: two outer beamforming microphones plus a third to cut wind and background noise, with an array designed for voice clarity in loud places. Battery runs up to 32 hours total with the case, which holds three extra power-ups, and the case itself supports Qi-compatible wireless charging. A quick charge gets you back to an hour of playtime in minutes. You also get hands-free "Hey Google" and Amazon Alexa, voice prompts in multiple languages, Bluetooth 5 with roughly 10 meters of range, and a kit that includes five sizes of ear tips and two sizes of stabilizers.
Buy it if you live in a mix of environments — trains, open offices, streets, cafés — and you want to control how much of that world you hear. It suits adults who take calls and want a voice assistant on tap.
Skip it if your main use is hard training. There is no IP rating listed here, and the rounded-tip in-ear shape with silicone enclosures is a comfort-first design, not a grip-first one. For heavy sweat, look at the other pair.
The Sport X20 attacks a different problem: earbuds that stay put and survive punishment. Its defining feature is the ear hook system — hooks that rotate up to 30 degrees and extend 4mm so you can dial in the position for your own ear shape. If standard tips slide out mid-run, that adjustability is the fix.
Durability is the other headline. The cavity design and soundcore's SweatGuard technology create a sealed interior, and the whole thing carries an IP68 rating: waterproof, sweatproof and dustproof. That is a genuinely rugged spec for a wireless earbud, and it means rain, sweat and gym grime are covered.
Audio leans toward motivation rather than neutrality. BassUp technology drives 11mm dynamic drivers — noticeably larger than the JBL's 6.8mm — with a 20Hz to 20KHz frequency range and 10 ohm impedance. Noise cancelling is both manual and adaptive, aimed at turning loud gyms into quiet zones by blocking clanging weights and background noise. Controls are touch-based with volume control on the earbud itself. Battery is strong in its own way: 12 hours on a single charge in normal mode, 48 hours with the case, dropping to 7 hours per charge and 28 total with ANC on, plus fast charging. Bluetooth 5 keeps the connection wireless, and the package includes a cable, charging case and eartips. Warranty runs 18 months.
Buy it if your earbuds are training gear. Runners, lifters, cyclists and anyone who has lost a bud to a treadmill will appreciate the hooks and the IP68 shell.
Skip it if ambient awareness and voice assistants are your priority. The spec sheet here is about blocking sound and staying locked in, not about letting the world back in.
• Best for ambient sound mode → JBL Tour Pro+ TWS. Smart Ambient is a named, app-controlled feature for hearing your surroundings on demand.
• Best for calls in noisy places → JBL Tour Pro+ TWS. Two beamforming outer mics plus a third for wind reduction, with hands-free Google and Alexa.

• Best for awareness-first commuting → JBL Tour Pro+ TWS. Adaptive ANC plus transparency is exactly the commute toolkit.
In my opinion, the JBL Tour Pro+ TWS is the better buy for most people, because ambient sound mode is the feature you will use every single day — on a train, at a desk, in a shop — while a rugged shell only matters if you genuinely train hard. The JBL pairs adaptive noise cancelling with real transparency, strong call mics and wireless charging, which covers the daily grind well. That said, if you are buying earbuds to sweat in, I would take the Anker soundcore Sport X20 without hesitation — the hooks and IP68 rating are the right tools for that job. Two different jobs, two different winners.
what is ambient mode on earbuds
Ambient mode lets outside sound into your earbuds through the microphones, so you can hear traffic, announcements or a person talking without removing them. On the JBL Tour Pro+ TWS this is called Smart Ambient and can be toggled by button or in the JBL app.

It is the same idea under a different name: a transparency setting that mixes the real world into your audio instead of blocking it. It pairs with noise cancelling — one mode shuts the world out, the other lets it back in.
what is ambient mode in earbuds
Ambient mode is your awareness switch. Instead of pausing music and pulling a bud out, you activate it and hold a conversation or listen for your stop. The JBL Tour Pro+ TWS offers exactly this via Smart Ambient; the Anker soundcore Sport X20 focuses its specs on adaptive noise cancelling and fit instead.
No. If your earbuds never meet sweat or rain, the JBL Tour Pro+ TWS's comfort-first design and ambient features matter more. The Anker soundcore Sport X20's IP68 rating is what you pay attention to when workouts and weather are part of the plan.
