Soundcore, Anker's audio brand, had never appeared in the RunMorph catalog, despite a broad sports lineup and a strong presence at French retailers. The AeroFit 2 fills that gap: an open-ear design with an adjustable earhook, 42 hours of battery life with the case, and a price that drops under 100 euros once the usual discounts kick in.

The AeroFit 2 is an open-ear earbud with an earhook that adjusts to 4 positions, listed at 129.99 euros but easy to find for 80 to 90 euros at most retailers. It bets on a record 42 hours of battery life with the case, an IP55 rating and bass boosted by BassTurbo technology, while promising to keep you aware of your surroundings on the run. Don't confuse it with the AeroFit 2 Pro, a higher-end model with active noise cancelling that costs more.
Anker and its audio brand Soundcore have ruled the affordable consumer earbud and speaker market for years, yet they were strangely missing from the RunMorph catalog, despite an already broad sports lineup (AeroFit, AeroClip, Sport X20) and heavy coverage in the French press. The AeroFit 2 fills that gap with a clear positioning: an entry-level open-ear model aimed squarely at Shokz OpenFit 2 fans, at a far more aggressive price once the usual discounts apply.
The principle is the same as on other open air-conduction earbuds: a hook holds the earbud above the ear canal without ever blocking it, so you stay fully aware of your surroundings when running on the road or in the city. Soundcore uses an earhook that adjusts to 4 positions instead of a fixed one, a design choice meant to fit a wider range of ear shapes.
| Brand | Soundcore (Anker) |
| Model | AeroFit 2 (not to be confused with the AeroFit 2 Pro, which has active noise cancelling) |
| Model number | A3874 |
| Type | Open-ear with 4-position adjustable earhook |
| Drivers | Racetrack 20 x 11.5 mm, BassTurbo technology |
| Audio codecs | LDAC (Android only), AAC, SBC, Hi-Res Audio certified |
| Bluetooth | 5.4, multipoint (2 devices at once) |
| Battery life | 10 h per charge, 42 h with the case |

| Water resistance | IP55 (dust, sweat, splashes) |
| Weight | 10 g per earbud |
| Microphones | 4 mics with AI-assisted noise reduction |
| Features | Real-time translation (100 languages), 8-band equalizer in the Soundcore app |
| List price | €129.99, street price seen between €79 and €90 |
On Soundcore's official store, the product shows 391 verified reviews, with 86% 5-star ratings and 12% 4-star ratings: a very high aggregate satisfaction score for a sports earbud in this price bracket.
The feature Soundcore pushes hardest is the earhook that adjusts to 4 positions, a different design from the fixed hooks of its direct rivals. The idea is to bring the driver closer to the ear canal to boost bass, a gain the brand puts at up to 7.5 dB compared with a non-adjustable hook. The 20 x 11.5 mm Racetrack drivers, paired with BassTurbo technology, aim to fix the classic weak spot of open-ear designs: bass that often sounds thin.
The LDAC codec, limited to Android devices, delivers better audio transmission than standard SBC on paper, but it's not available on iPhone. Real-time translation in 100 languages is more gimmick than must-have for sports use, but it shows Soundcore's strategy: stack up software features to stand out in a crowded market.

RunMorph's advice: make sure you're ordering the AeroFit 2 and not the AeroFit 2 Pro if you want the best value. The two models look very similar on retailer product pages.
We'll say it plainly rather than gloss over it: at the time of writing, independent testing with hard data on this exact model is limited. Several pages we checked mostly rehash the official product page or marketing visuals instead of documenting original real-world use, so we can't cross-check 3 independent reviews for this model. One reliable data point does exist: the aggregate rating of 391 verified customer reviews on the official store, which is overwhelmingly positive (86% 5 stars). Reviewers specifically mention a good compromise for running compared with regular in-ear earbuds, and praise the sound transparency that keeps them aware of traffic.
One discrepancy is worth flagging rather than smoothing over: the water resistance rating varies between sources. Soundcore's official page and most retailers list IP55, while at least one third-party spec sheet lists IPx4. The manufacturer's spec sheet is the reference here (IP55), but the gap shows that for this kind of spec, you should trust the official product page over aggregated comparison-site listings.
| Criterion | Soundcore AeroFit 2 | JBL Endurance Peak 3 |
|---|---|---|
| Type | Open-ear with earhook | In-ear with Powerhook earhook (sealed) |
| Street price | ~€80-90 | ~€70-90 |
| Battery life | 10 h / 42 h with case | 10 h / 50 h with case |
| Water resistance | IP55 | IP68 |
| Weight | 10 g per earbud | 76 g (earbuds + case) |
| Wireless charging | Yes (Qi) | No |
The choice mostly comes down to the design you want. The JBL is more water resistant and better suited to pouring rain thanks to its IP68 rating, while the Soundcore leaves your ears completely open and adds wireless charging. Neither has a clear edge on battery life or price: the difference comes down to how you'll use them.
The AeroFit 2 is for runners who want full awareness of their surroundings, in the city or on roads open to traffic, without breaking the bank. If you need maximum water resistance for very rainy runs, the JBL Endurance Peak 3 is better equipped with its IP68 rating. With a bigger budget and a more proven open-ear option in real-world testing, the Shokz OpenFit 2 stays a step ahead on independent reviews.
Running with music is good. Running with a structured plan is better. The RunMorph training plans help you shape your sessions, headphones or not.
The Soundcore AeroFit 2 makes a solid entry into the sports segment with strong battery life, a well-designed earhook and an aggressive street price. The brand still lacks independent real-world testing on this exact model, and the IP55 rating falls short of the best in-ear earhook models on the market.
7/10. Good battery life for the money if you prefer open-ear and situational awareness, best kept for runs without heavy rain. Double-check that you're ordering the AeroFit 2 and not the AeroFit 2 Pro before you buy.
