Csasan: 64 of 186 negative reviews (34%) point at the same thing — Other issues. “écouteurs 100% des bons sons 👌”
Soundcore: 19 of 65 negative reviews (29%) point at the same thing — Sound quality. “sound using teams is terrible. do not recommend for office use.”
The platform score hides this. At 4.4 vs 4.4, one should spend its budget on Other, the other on Sound — spend it the wrong way and the next generation stays at 4.4.

"Other" shows up in only 12 of Soundcore's complaints (18%), and "Sound" in only 36 of Csasan's (19%). The two products fail at different links — the improvement budget should not go to the same place.
Only 0 of Csasan's 4 3★ reviews mention "Other" (keyword tagging, auxiliary) — mid-rating users have not been burned by it yet; once they are, they go straight to 1-2★. Fixing this moves the rating more than polishing what is already "okay".
False-advertising / not-as-described wording appears in 1-2★ reviews (Csasan 5, Soundcore 3). This is the cheapest fix of all — revising the copy alone can move the needle. Typical wording: "and last but not least, the sound is good, but it's not excellent (as advertised)."

Typical Positive Review:
| Strength | Mentions | Ratio | Type | Quote |
|---|---|---|---|---|
| Sound Quality | 42 | 13.1% | feature | The sound quality is amazing for the price point — clear audio, strong bass, and loud volume without sounding distorted. |
| Value for Money | 38 | 11.8% | value | For $40 these are a steal! Makes no sense to me to spend 7x the money for something that works so well. |
| Active Noise Cancelling | 35 | 10.9% | feature | The real-time adaptive noise cancelling works shockingly well for this price tier. Office chatter fades. HVAC and jet engine hums disappear. |
| Battery Life | 28 | 8.7% | feature | The battery life is exceptional and I think it beats out my pair of P2i earbuds. I wear the P31i's for hours, listening to music at the highest volume and they haven't died once. |
| Comfortable Fit | 25 | 7.8% | experience | They're the most comfortable buds I have ever worn, beating out the more expensive ones by a lot! |
| App Features & Customization | 24 | 7.5% | feature | The app is really what sets these above everything else. It does a fit test, then runs an EQ test so that the sound is tailored specifically to your hearing. |
| Easy Setup & Connectivity | 20 | 6.2% | experience | These connected easily, without any hassle, and both earbuds worked exactly as they should from the start. |
| Call Quality | 16 | 5% | feature | Call clarity was excellent and this is something I am very picky about due to having worked on crisis calls for many years in the past. |
| Secure Fit / Stay in Ears | 15 | 4.7% | experience | They stay in my ears perfectly. The Moondrop falls off my ears all the time. |
| Translation Feature | 12 | 3.7% | feature | The AI translation was 98% accurate, missing only one or two words but still quite good. |
| Durability & Build Quality | 11 | 3.4% | feature | I dropped the left one and it went straight to the bottom of the pool. A few hours later it's dry and to my surprise, it works. 10/10 on these. |
| Multipoint Connection | 9 | 2.8% | feature | The fact that it connects simultaneously to your PC and phone is just so convenient. |
| Waterproof / IP Rating | 8 | 2.5% | feature | They are waterproof and the language translation is a fun perk that actually works. |
| Hearing Test / Personalization | 7 | 2.2% | feature | The very best thing about these is that they have a hearing test that then accommodates for any hearing issues! My left ear has hearing loss, and I finally have ear phones that make up for that! |
| Transparency Mode | 7 | 2.2% | feature | The 'transparency' mode lets you talk to others without having to remove the buds. |
| Touch Controls | 6 | 1.9% | feature | The earbud touch controls don't start to do crazy things when all you need to do is adjust the fit. |
| Design & Style | 6 | 1.9% | experience | The carrying case feels solid and the overall design looks clean and premium. |
| Brand Reliability | 5 | 1.6% | experience | I'm a huge fan of Soundcore products. I've never owned a Soundcore product that I haven't liked. |
| Wind Noise Reduction | 4 | 1.2% | feature | Very good adaptive noise cancelling with wind noise blocking. |
| Customer Service | 3 | 0.9% | service | One of the earbuds seemed to have issues once or twice, but when I contacted the company, they completely took care of me! |

| • Technological advances in smartphone-based translation could make dedicated earbuds obsolete for casual users. |
| • Quality control issues, such as earbuds failing within months, erode trust in the entire product category. |

Note: Actual return rate is typically higher than review mention rate (many users return without leaving reviews); the above is a conservative lower bound. The reason breakdown uses return mentions with a stated reason as its denominator, which differs from the return-mention count on the left (one mention may carry several reasons). Estimated monthly loss uses the unrounded return ratio.
