M800 Wireless Review: Real User Experience After 3 Months

I've been using the M800 Wireless earbuds as my daily driver for music, calls, and workouts for the last three months. I bought a retail unit with no special discounts and used them across commuting, remote work calls, running, and streaming shows. This review is my honest, hands-on account: what I liked, what frustrated me, and how the M800 stacks up against alternatives I own or tested alongside it.

Why I bought the M800 Wireless

I was looking for a set of true wireless earbuds that balanced solid sound, reliable Bluetooth connectivity for both laptop and phone, and decent active noise cancellation (ANC) without costing a premium. I also wanted something comfortable enough to wear for long work sessions and with a case that charged quickly between uses. After seeing a few mixed-but-promising write-ups, I decided to try the M800 to see if it could replace the pair I was using at the time.

Initial impressions and build quality

Out of the box the M800 felt lightweight and minimal. The case has a matte plastic finish that's resistant to fingerprints, but you can tell it's not metal — which is fine by me because it keeps the weight down. The hinge on my unit feels a bit thinner than I'd prefer; it works perfectly now, but I worry it might be the first part to wear over years of use.

The earbuds themselves are about 6–7 grams each, with a rounded stem that tucks into the ear. The silicone tips provided a comfortable seal for my ears, and the package included three sizes so I could test for the best fit. I noticed right away that the M800's shape leans toward comfort over aggressive isolation: in a crowded subway the ANC helps, but the passive seal is not as "in-ear locked" as some other models I’ve tried.

Setup and daily use

Pairing with my smartphone was straightforward. The M800 uses Bluetooth 5.3 and supports AAC and aptX; my phone connected with AAC by default, and my laptop picked up aptX when supported. Multipoint pairing worked reliably: I had them connected to my phone and laptop simultaneously, and switching audio between devices was generally seamless. There were a couple of moments where the left bud briefly dropped connection when walking through heavy interference (cafés with many devices), but reconnecting happened within a couple of seconds without manual intervention.

Touch controls are on the stem and are sensitive. I prefer tactile buttons because I often adjust volume while jogging, and the M800’s touch surface registered accidental taps when I adjusted the fit. You can customize the controls through the companion app (more on that below), which helped reduce accidental skips after I remapped single taps to track controls instead of play/pause.

Sound quality: what I heard

In my experience the M800 favors a warm, slightly bass-forward presentation out of the box. That suited the genres I listen to most — indie, electronic, and podcasts — but I noticed some smoothing of midrange detail when I listened to acoustic or vocal-centric tracks. There’s a pleasing punch to tracks with heavy low-end, but if you want pinpoint instrument separation in classical recordings or audiophile mixes, the M800 doesn’t quite reach that level.

The soundstage surprised me: while true wireless in-ear devices are never as spacious as over-ear headphones, the M800 creates a decent sense of air. Vocals sit a bit behind the bass compared to neutral earbuds, which gives music a relaxed vibe rather than a clinical one. Using the app's EQ, I could dial back the bass and bring the mids forward for clearer vocals when I wanted to focus on dialogue or podcasts.

Latency was good for watching videos. With aptX on my laptop I didn't notice lip-sync issues when streaming shows or video calls. For competitive gaming, however, there was still a slight delay compared to wired headsets. If low-latency gaming is your priority, these aren’t the ideal pick.

Active Noise Cancellation (ANC) and transparency

The M800's ANC is what I'd call competent but not market-leading. In a noisy café or on a bus, ANC reduced the rumble and mid-frequency noise effectively — enough to lower volume needs and reduce fatigue. It didn't completely erase sharp, high-frequency sounds like sudden sirens or nearby chatter. I appreciated the "ambient" or transparency mode for crossing streets or talking to coffee shop baristas; it sounded natural and didn't introduce the plasticiness some transparency modes do.

One practical note: ANC impacts battery life noticeably. When I left ANC on continuously, my daily run-time dropped by about 20–30% compared to using ANC off with just passive isolation.

Microphone and call quality

In my experience the M800 performs well for calls in quiet environments: voice comes through clear to the person on the other end, and background room noise is handled reasonably. Outdoors or in windy conditions, the mic picks up breath and wind noise more than I expected. I found that cupping the earbud stem with my hand reduced wind noise but made the setup look awkward during video calls.

For lengthy calls I sometimes noticed that my voice sounded slightly tinny after about an hour, which suggests the mic processing favors clarity over natural warmth. That was acceptable for work calls, but not ideal for voice-over or content creation where a more neutral capture is preferred.

Battery life and charging

Manufacturers often quote optimistic numbers, and the M800 is no exception. In my usage over three months I measured the following:

• Earbud runtime: About 7–8 hours with ANC off, 5–6 hours with ANC on (moderate volume).
• Charging case additional charge: ~24 additional hours (three full charges), bringing total to ~31–32 hours with ANC off.
• Quick charge: 10 minutes in the case gave me roughly 90 minutes of listening — handy when I forgot to charge overnight.
• Full recharge: Around 60–70 minutes from empty for the case via USB-C.

After three months of daily use, battery capacity felt stable; I didn't notice a significant drop. That said, any long-term battery degradation would require more time to assess conclusively.

Companion app and customization

The M800 app is simple and useful. It offers an EQ with presets, manual EQ, ANC and ambient mode toggles, and control remapping. The EQ made the most noticeable difference for me — dialing down the low-end and boosting upper mids improved vocal clarity significantly.

Two app-related gripes: the app sometimes takes a couple of seconds to reflect the earbuds’ battery percentage after a disconnect/reconnect, and the firmware update process required me to stay close to the phone for several minutes (fine, but inconvenient if you're impatient). Still, I appreciated being able to save EQ profiles for "Music," "Podcasts," and "Gym."

Durability and water resistance

The M800 has an IPX4 rating (splash- and sweat-resistant). I wore them while running in light rain and during sweaty HIIT sessions; they held up fine. I wouldn't submerge them or intentionally expose them to heavy downpours. After three months, normal wear signs are limited to slight scuffing on the case exterior and minor earbud tip discoloration from pocket lint and sweat — nothing that affects performance.

What I appreciated

• Reliable multipoint Bluetooth pairing that lets me jump between laptop and phone without fuss.
• Comfortable fit for long listening sessions — I could wear them for whole workdays with only minimal ear fatigue.
• App-based EQ that genuinely improved clarity for podcasts and vocals.
• Respectable ANC that reduces low-frequency rumble on public transit.
• Good quick-charge capability when I needed a fast top-up.

What bothered me

• The touch controls are overly sensitive out of the box and caused accidental skips until I remapped them.
• ANC softens the highs slightly, which affected vocal presence in some music tracks.
• Microphone performance in windy conditions is mediocre.
• The case hinge feels less robust than the rest of the build.
• Occasional brief left-ear disconnects in areas with heavy RF interference.

Pros & Cons

• Pros:
• Comfortable fit for extended use
• Good sound with customizable EQ
• Multipoint Bluetooth works reliably
• Decent ANC for daily commuting
• Quick charge feature is genuinely useful
• Cons:
• Touch controls too sensitive initially
• Microphone struggles in windy environments
• ANC reduces some high-frequency detail
• Case hinge could be sturdier
• Not the best choice for competitive, low-latency gaming

Comparison: M800 vs. Competitors

Buying guide: Is the M800 right for you?

In my experience, deciding whether the M800 is the right fit depends on a few practical considerations. Here’s what I would advise based on how I used them:

1. What do you listen to most?

If you mostly listen to pop, electronic, or bass-forward tracks and want a fun, punchy sound, the M800 will likely satisfy you. If you're an audiophile who prioritizes studio-like neutrality or extreme detail, you may prefer a more neutral model or one that supports LDAC for high-bitrate streaming.

2. How important is ANC?

If you commute on buses or subways and need to reduce constant hums and rumbles, the M800’s ANC provides meaningful relief and reduces listening fatigue. If you want industry-leading ANC that silences everything around you (including more high-frequency sounds), consider a competitor with top-tier ANC.

3. Do you take calls outdoors often?

For quiet indoor calls, the mic is solid. For frequent outdoor calls, especially in wind, take into account that the mic processing struggles — you might want a model with dedicated wind reduction mics.

4. Are you a multi-device user?

The M800’s multipoint Bluetooth is a real convenience if you switch between laptop and phone often. In my workflow, that feature saved me time and avoided the annoyance of re-pairing.

5. If you game or watch low-latency video

For casual gaming and streaming video, latency is fine. If you play competitive, fast-paced games where audio timing is critical, a wired headset or a gaming-focused low-latency mode will serve you better.

Practical tips I learned while using the M800

• Try all ear tip sizes and test the seal before judging bass — a better seal made the biggest improvement in clarity.
• Use the app EQ profiles: they can transform the earbuds from bass-forward to much clearer for voices.
• Turn off ANC during long listening sessions at home to save battery and preserve high-frequency detail.
• Carry a small cleaning cloth and periodically wipe the charging contacts to avoid connection issues.
• If you often wear earbuds for calls and exercise, consider pairing the M800 with a wind muff or a hood when calling outdoors in wind to reduce mic noise — it's an awkward workaround but effective.

Final thoughts and conclusion

After three months with the M800 Wireless, I can say they’ve become my go-to pair for everyday use. What I found was a comfortable, versatile earbud with a pleasing sound signature and practical features like multipoint and quick charge that make life easier. The app-based EQ is a big plus, and the ANC is good enough for most urban environments.

At the same time, I noticed real limitations: the touch controls needed tuning, the microphone isn't great in windy conditions, and the ANC slightly softens highs. None of these are dealbreakers for my daily routine, but they are worth knowing if those aspects matter to you.

If you want a balanced, user-friendly set of earbuds that perform well across music, calls, and commuting without breaking the bank, the M800 is a solid choice. If you demand the very best ANC, highest-fidelity codecs like LDAC, or industry-leading wind reduction for outdoor calls, you might want to compare a few competitors first.

Overall, in my experience the M800 provides a compelling mix of comfort, useful features, and enjoyable sound for everyday life. After three months of consistent use, I still reach for them first when I walk out the door or sit down at my desk — and that's the simplest test of an accessory's value.
