E100 Truly Wireless Honest Review — Is the Hype Justified?

I've been using the E100 Truly Wireless earbuds for roughly four months now — commuting, working from coffee shops, taking long walks, and pairing them with a laptop for video calls. I bought them at full price (no review unit, no sponsorship), and I wanted to see whether the positive buzz around them matched real-world use. What I found was a mix of pleasantly surprising strengths and a few annoyances that make them great for some people and not the best fit for others. Below I break down my experience in detail so you can decide whether they fit your priorities.

First impressions and build quality

When I first opened the E100 case, I immediately noticed how compact and light the case is — it easily slipped into my jeans pocket without feeling bulky. The case is matte plastic with a subtle gloss on the hinge area. After several months, it has picked up a few tiny scuffs where I toss it in a backpack, but nothing structural. The earbuds themselves have a low-profile, rounded stem design that sits mostly inside my ear canal. I appreciated the understated look: no flashy branding, just a clean finish in my charcoal color.

Fit-wise, I found them comfortable for long listening sessions. I swapped through the included silicone tips and landed on the medium size for the best seal. I’m someone who often needs multiple tip sizes, and the E100’s tips gave me a reasonably secure seal that stayed put during walks and light workouts. For very vigorous runs, they’re not as secure as a dedicated sport model with ear hooks, but I didn’t experience random dropouts or falling-out incidents during daily movement.

Battery life and charging — what my routine looked like

Battery life has been one of the E100’s strong suits for me. In my testing over several weeks I averaged around 6.5 to 7 hours of continuous playback at roughly 60–70% volume on a single earbud charge. That translates to around 24–26 hours total with the case when I started fresh in the morning — and after a couple months of typical daily charging cycles I still get very similar numbers. Charging the earbuds from empty to full takes about 1.5 hours; the case charges in roughly 2 hours via USB-C. I appreciated that the case uses USB-C (no micro-USB), but note there’s no wireless charging feature.

One practical point: the quick-charge feature works well for me. A 10–15 minute top-up in the case gives around an hour of playback, which has saved me when I left the house with a low charge. That's been handy for travel days when I wanted one full flight without hunting for an outlet.

Sound quality — real listening notes

Sound is where I spent the most time with the E100. In my experience they lean slightly toward a warm V-shaped signature: bass is present and impactful without being boomy, mids are slightly recessed but still detailed enough for vocal-forward tracks, and treble is crisp with just enough shimmer to keep acoustic instruments and electronic highs interesting. I listened to a broad set of songs — jazz, lo-fi, indie rock, pop, and a bit of bass-heavy electronic — and found these earbuds handle variety well for everyday listening.

What I appreciated specifically: kick drums and basslines have weight and punch that translate well in commuting or noisy environments. Vocals can sometimes sit a touch behind the bass, especially on complex mixes, but nothing I’d call thin or veiled. Where they struggle is extreme high-end detail: very subtle micro-details and the absolute top treble air that you get on higher-end flagship earbuds aren’t as present here. For most listeners, though, I think the overall tuning will feel lively and enjoyable rather than clinical.

There is an EQ option in the companion app (more on the app later), and I used a small mid-boost to bring vocals forward in podcasts and acoustic music. That made a noticeable improvement without introducing distortion.

Active Noise Cancellation (ANC) and passive isolation

The E100 includes ANC, and here my experience was mixed. In low-frequency, steady-state noise — like airplane engine rumble or bus vibration — the ANC reduces a meaningful amount of background energy. I found it comforting on a 3-hour flight when I wanted to reduce the cabin hum. However, it’s not magic: sudden noisy sounds (door slams, loud chatter nearby) are still audible. ANC does a decent job at muting the steady drone, but don’t expect the level of noise removal that flagship ANC models deliver.

Passive isolation (from the ear tips and seal) contributes significantly to the overall attenuation. With the right tips, I could rely on passive isolation for most daily commutes, and the ANC layered on top made things pleasantly quiet.

Connectivity, latency, and call quality

Connectivity has been stable in my use. The E100 pairs quickly with devices and maintains a steady connection within a typical pocket-to-phone distance. It uses Bluetooth 5.x (the packaging states 5.2), and I didn’t experience frequent dropouts. That said, I did notice occasional re-pairing quirks when switching rapidly between my laptop and phone — it’s not a true multipoint pairing solution, so switching devices requires manually reconnecting or disconnecting sometimes.

Latency is fine for watching videos and casual gaming on my phone, but it’s not low-latency pro-level. When playing competitive games, I felt a subtle lip-sync lag (maybe around 100–150ms) that could matter to gamers who need tight audio-visual timing. For video streaming and social apps, it was unnoticeable most of the time.

Call quality is acceptable for everyday conversations. My voice sounded natural to callers in quiet indoor settings. Outdoors on windy streets, the microphones struggled with wind and background noise — voices sounded a little distant to the other party, and I occasionally received feedback that I sounded muffled during busy street crossings. If you make a lot of calls in noisy environments, you should be aware that these won't match the clarity of higher-priced earbuds with multi-microphone beamforming systems.

Controls and app experience

The E100 uses touch controls on each bud. Single and double taps are reliable for play/pause and next-track commands, but long-press gestures for ANC toggle or voice assistant have been hit-or-miss for me; sometimes I triggered the wrong action because the touch surface is sensitive. After a week, I adapted by favoring single taps and using my phone for advanced commands.

There’s a companion app that offers basic settings: firmware updates, EQ presets, and an on/off toggle for ANC and transparency modes. I appreciated the firmware updates — one update fixed a pairing issue I ran into early on and improved battery reporting accuracy. The EQ is lightweight but useful: the presets are fine, and there’s a 5-band manual EQ that let me nudge mids upwards when I wanted clearer vocals. The app UI is simple and not packed with features, but it does what I need without being cluttered.

Durability and daily life

After four months I have no functional failures. The earbuds have endured sweat from workouts and occasional rain on walks; they carry an IPX5-like tolerance on the box (meaning splash/sweat resistant rather than fully waterproof). I wouldn’t submerge them, but they held up for gym sessions and rainy commutes. The case hinge remains firm and the magnets that hold the buds in place are still strong. Battery degradation has been minimal in my timeframe, though longer-term owners may see gradual capacity loss as with any rechargeable device.

Pros & Cons

• Pros:
  • Excellent battery life for the price — around 6.5–7 hours per charge and multiple full charges from the case
  • Warm, engaging sound signature with punchy bass that works well for commuting and casual listening
  • Comfortable fit for long sessions and good passive isolation with the right tips
  • Compact case and USB-C charging — convenient for daily carry
  • Companion app with EQ and firmware updates — practical and useful
• Cons:
  • ANC is useful but not class-leading — better for steady hums than for sudden noises
  • Call quality drops in wind and very noisy environments
  • No multipoint pairing; switching devices can be a small hassle
  • Touch controls can be overly sensitive and occasionally unreliable for long-press actions
  • No wireless charging on the case

Comparison table — E100 vs. Typical Alternatives

Who should buy the E100?

In my experience, the E100 is a solid choice if you want a reliable, full-featured pair of earbuds without paying flagship prices. They’re great for:

• Commuters who want long battery life and punchy sound for music during travel
• People who prioritize sound enjoyment over absolute studio accuracy
• Users who want a compact case and USB-C charging without needing wireless charging
• Anyone who values firmware updates and a basic EQ in an app

They’re less ideal if you need top-tier ANC, exceptional call clarity in very noisy/outdoor conditions, multipoint pairing across multiple devices, or ultra-low latency for competitive gaming.

Buying guide — what to check before you buy

If you’re considering the E100 or similar true wireless earbuds, here are the practical things I checked during my purchase and testing — things I recommend you check too.

• Battery real-world numbers: Look for independent reviews that measure playback time rather than just manufacturer claims. I measured 6.5–7 hours in daily use; your mileage will vary by volume and codec.
• ANC effectiveness: Consider whether you need ANC for steady hums (planes, trains) or for active noisy environments (busy cafes). The E100 handles steady noise well but isn’t the quietest ANC on the market.
• Fit and tips: Check the shape and whether the manufacturer includes multiple tip sizes. A good seal will make a big difference for sound and passive isolation.
• Call quality tests: If you take many calls outdoors, look for samples or test in a windy area if possible. Microphones vary wildly.
• App features: Decide whether you want a simple app for EQ and updates or a full-featured audio suite. The E100’s app is functional and helpful for tuning.
• Latency and codecs: If you game, check for low-latency modes and supported codecs. The E100 is fine for video but not the best for competitive gaming.
• Durability and warranty: Confirm the IP rating and warranty terms. I found the E100 resilient for gym sessions (sweat-resistant) but I wouldn’t use them for swimming or heavy exposure.
• Charging preferences: If wireless charging is a must-have for you, note that the E100 case does not support it — but you do get USB-C fast charge.

Final thoughts

After using the E100 Truly Wireless earbuds for several months, I can say they deliver excellent everyday value. In my day-to-day life they became the set I reached for most often: long battery life, satisfying bass, a comfortable fit, and a useful companion app. The ANC and call performance are good enough for most situations but not exceptional; if those two areas are your highest priorities, you may want to look at higher-end alternatives.

What surprised me most was how balanced the overall package felt. There are trade-offs, of course — touch controls that sometimes misfire, no wireless charging, and occasional struggles in windy calls — but nothing that felt like a dealbreaker for my usage. If you want enjoyable sound, dependable battery life, and practical features without flagship pricing, the E100 is worth considering. In my experience, the hype around them is mostly justified for everyday users who want a solid, reliable set of earbuds rather than the absolute best in noise cancellation or call fidelity.
