Activbuds S 250 Review: Real User Experience After 3 Months

Introduction

I've been using the Activbuds S 250 for just over three months now, carrying them through the morning commute, conference calls, midday runs, and long evenings of music and podcasts. I bought these with the intention of finding a practical, everyday pair of true wireless earbuds that could handle commuting noise, keep up during workouts, and still sound good for relaxing at home. What I found was a mostly dependable pair with a few clear strengths and some annoyances that only showed up over time. This review is grounded in my day-to-day experience: setup, comfort, sound, battery, call quality, durability, and how they compare to other earbuds I’ve used recently.

Unboxing and First Impressions

Out of the box, the S 250 feels like a solid mid-range offering. The charging case is compact with a matte finish that resists fingerprints; the earbuds themselves are lightweight and have a semi-matte plastic feel with small glossy accents. Pairing with my phone was straightforward — I opened the case, saw the prompt on my phone, and paired in under a minute. The manufacturer’s app (which I installed the first day) offered firmware updates, an EQ, and some toggles for ANC and transparency modes. I ran the first firmware update the night I got them, which fixed a few early glitches I noticed in call switching.

Fit and Comfort

In my experience, fit is one of the most personal things, and the S 250 did pretty well. The earbuds come with three sizes of silicone tips — small, medium, and large — and the medium tips worked best for me. I found them comfortable for multi-hour sessions and they didn't cause soreness after a full day of use. They sit shallow-to-medium in the ear canal compared to some deep-fit earbuds, which I appreciated because they didn't create that "blocked ear" feeling.

For workouts, I took them on several runs and the fit stayed secure. I did notice that during intense interval sessions with a lot of head movement, I had to re-seat an earbud once or twice, but that was rare. Sweat resistance is advertised and in my rainy run tests they held up fine; I didn’t see any water-related failure after three months.

Sound Quality — Daily Listening and Genres

One thing I appreciated right away was how balanced the sound felt for typical listening — not overly bass-heavy but with enough warmth to make pop and electronic music enjoyable. I tested with a wide range: acoustic singer-songwriter tracks, orchestral pieces, podcasts, and bass-forward electronic music.

What I found was:

• Vocals and midrange are clear and present. Podcasts and dialogue were easy to follow even on noisy buses.
• Bass response is punchy but not overwhelming. Tracks that rely on deep sub-bass will sound tighter than booming.
• Highs are detailed without being harsh, though cymbal-heavy jazz pieces occasionally lost a little sparkle at higher volumes.

The onboard EQ in the app helped me tailor the signature. I preferred a small bass boost for workouts and a flatter profile for long listening sessions. I noticed a modest improvement when switching from SBC to AAC on my phone (my device chose AAC automatically), particularly for clarity in the upper mids.

Active Noise Cancellation (ANC) and Transparency

I used the S 250’s ANC daily on the train and in coffee shops. It’s not flagship-class ANC, but it’s effective for mid-frequency noise like conversation hum and general commuter background noise. What I noticed:

• ANC reduces steady noise (air conditioning, subway rumble) noticeably, making it easier to focus on music or an audiobook.
• It struggles with very loud or sudden noises like train brakes or a loud announcement — those still come through and can be jarring.
• Transparency mode is natural and didn’t add a mechanical echo like I’ve heard on cheaper buds; it’s comfortable for quick conversations without removing an earbud.

After a firmware update in my second month, I felt ANC behavior improved slightly — a small nudge in low-frequency suppression and fewer crackling moments when toggling modes.

Battery Life and Charging

The manufacturer claims a certain run time, but in my real-world usage I got slightly different results. With ANC turned off, I typically got around 6.5–7 hours of continuous playback on a single charge. With ANC on, that dropped to about 4.5–5 hours depending on volume and whether I used calls. The compact case provided about two full extra charges, bringing total real-world day-to-day battery to roughly 20–22 hours before I needed to plug the case in.

Charging the case from empty to full on my USB-C charger took about 90 minutes, and a 15-minute quick charge usually gained enough battery for an hour or two of listening — handy when I forgot to charge overnight. I didn't notice significant battery degradation across the three months; capacity remained consistent for my typical use.

Call Quality and Microphone Performance

Call quality is where many earbuds show their true colors. In quiet indoor calls, callers said I sounded clear and natural. On walks and during commutes, external noise reduced call clarity a bit — wind is the real enemy here. I tested the S 250 in a windy environment and my voice came through as muffled at times; the earbuds' wind reduction algorithm handled light breeze but not gusts.

For daily video calls and quick catch-ups, they were reliable. For long outdoor phone calls in windy conditions, you may notice degradation.

Bluetooth, Connectivity, and Latency

Bluetooth connection was mostly stable with my phone and laptop — I experienced a couple of short dropouts in places with heavy Wi-Fi congestion, but reconnects were automatic and quick. Multipoint support was limited; I could manually switch between devices without too much hassle, but they did not hold simultaneous connections to two devices as seamlessly as some higher-end models I've used.

For video streaming and casual gaming, latency was reasonable. I noticed a slight lip-sync delay in a fast-paced mobile game, but it wasn’t game-breaking. The branded low-latency or game mode in the app reduced perceptible delay when I needed it for short gaming sessions.

Build Quality and Durability

After three months of daily use — handbag drops, pocket living, and a few rainy runs — the S 250 showed only minor cosmetic wear. The case hinge remains solid, and the magnetic earbuds still snap in cleanly. I cleaned the silicone tips periodically; the process is straightforward and the tips are easy to remove and replace.

I did not experience firmware-caused bricking or long-term disconnections. The manufacturer pushed a couple of firmware updates that improved call switching and ANC behavior. Overall I felt the product’s longevity was acceptable for this price range.

Issues and Disappointments

One thing that bothered me was the occasional hiccup in auto-pause when removing one earbud. It worked most of the time, but sometimes playback would continue even after I took an earbud out, requiring a manual pause. Another small annoyance: the capacitive touch controls are sensitive and occasionally misinterpreted gestures (e.g., a single tap registered as a double tap), which I fixed somewhat by switching to physical-press-like taps, but that’s not ideal.

Also, if you’re a heavy traveller who needs top-tier ANC to block aircraft noise or very loud public transit, the S 250 won’t match flagship models. It feels like a thoughtful mid-range ANC implementation rather than a market-leading one.

Pros & Cons

• Pros:
  • Comfortable fit for multi-hour sessions
  • Balanced, pleasant sound signature with useful onboard EQ
  • Effective mid-level ANC for commuting and office noise

Buying Guide: What to Consider Before You Buy

If you’re considering the Activbuds S 250, here are the practical questions I asked myself before buying, and tips I learned from daily use:

1. What will you use them for?

Think about primary use: commuting, workouts, gaming, or calls. I wanted a jack-of-all-trades, and the S 250 fits that role. If you need clinical studio accuracy or the absolute best ANC for plane travel, look higher up the range.

2. Battery life — advertised vs. real world

Look beyond the headline battery claims. Check how many hours you need per day and whether the case offers enough extra charges. In my experience, plan for ~20 hours total between charges for daily portability with ANC on and off.

3. Fit and comfort

Make sure the vendor has a good return window or trial period. I recommend trying different tips and wearing earbuds for a couple of hours at home to check for fatigue. Lightweight, shallow-fit designs like these often suit a wider group of ears.

4. ANC and noise environment

Mid-level ANC like the S 250’s is great for steady background noise, but not a substitute for premium systems on aircraft. Consider whether you need noise-cancelling for office focus or for travel — the S 250 is more the former than the latter.

5. Calls and mic performance

If you take a lot of outdoor calls, check reviews specifically for wind and street noise handling. Indoor call clarity is a safer bet with the S 250; outdoors, expect some trade-offs.

6. App features and firmware support

An app with EQ, low-latency mode, and firmware updates is a plus. I appreciated firmware fixes during my three months; that improved my experience. If ongoing manufacturer support matters, look for brands that update regularly.

7. Connectivity needs

If you need seamless multipoint (two devices simultaneously), confirm the model supports it. For me, occasional manual switching was acceptable. If you expect heavy device switching, prioritize robust multipoint support.

8. Durability and warranty

Check IP ratings if you sweat a lot or plan to use them in wet conditions. Also verify the warranty period and how easy returns are — a good return policy made me comfortable buying and testing these for daily use.

Practical Tips From My Use

• Try all ear tip sizes — finding the right seal improved bass and ANC for me.
• Use the app’s EQ presets as starting points; small adjustments made the biggest difference.
• Keep firmware updated — I saw meaningful improvements after one update.
• For long battery life, keep ANC off when you don’t need it and use quick-charge when pressed for time.
• Clean the mesh and tips regularly to maintain sound clarity and hygiene.

Conclusion

After three months with the Activbuds S 250, my overall takeaway is that these are a dependable, well-rounded pair of true wireless earbuds suited for everyday users. In my experience they strike a good balance: comfortable for long sessions, pleasant sounding across genres, and equipped with a usable ANC that helps in day-to-day commuting and office situations. They aren’t perfect — wind handling and touch-control quirks were recurring annoyances — but the positives outweighed the negatives for my use-case.

If you want mid-range earbuds that handle a bit of everything without demanding constant fiddling, the S 250 is worth considering. If your priorities are best-in-class noise cancellation for frequent flights, or studio-level audio for professional listening, you’ll want to look higher. For my daily routines — calls, music, podcasts, and the occasional workout — the Activbuds S 250 have become my go-to companion.
