Gemercy I35 Wireless Earbuds: Long-Lasting Bluetooth Earbuds with Great Sound

Tired of your wireless earbuds dying after just a few hours of listening? Looking for a solid pair of Bluetooth earbuds with killer battery life? Enter the Gemercy I35 Wireless Earbuds. With an advertised 100 hours of playtime on a single charge, these around-the-neck style earbuds aim to keep the music going and going. But with such bold battery claims, how do the rest of the features stack up? Let’s dive in for a comprehensive review.

Overview

The Gemercy I35 Wireless Earbuds is a Bluetooth 5.1 neckband-style wireless earbud released in late 2021. Featuring an adjustable silicone neckband for comfort and stability, 10mm drivers in each earbud for sound, and onboard controls for playback and volume, the Gemercy I35 Wireless Earbuds covers all the basics expected of wireless earbuds. But where they really stand out is with the claimed 100-hour battery life — almost unheard of for a wireless audio product.

Other handy features include IPX5 waterproofing, built-in magnets to secure the earbuds when not in use, and integrated microphone for phone calls. Overall, they seem to check all the boxes for neckband wireless earbuds. But how do they actually perform? Let’s break it down.

Design & Comfort

Starting with the design, the Gemercy I35 Wireless Earbuds sports a smooth silicone neckband that is flexible and lightweight. I found it quite comfortable to wear around my neck for extended periods. The neckband contains the bulk of the battery and Bluetooth technology, keeping the earbuds lightweight.

The earbuds themselves have an ergonomic in-ear fit that was very comfortable for my ears. The kit includes 3 sizes of silicone ear tips to dial in the perfect fit. Once in place, the earbuds are surprisingly secure and stable when moving around.

Rounding out the thoughtful design are magnets inside each earbud so they snap together around your neck when not in use. This avoids any flailing wires which is a nice touch.

Overall, the Gemercy I35 Wireless Earbuds nails the comfort and fit. I barely notice I’m wearing them most of the time.

Sound Performance

Moving onto sound quality, the Gemercy I35 Wireless Earbuds punches above its weight class. With 10mm drivers in each earbud, I was impressed by the dynamic sound these pumped out.

The sound profile provides pleasing lows and mids. Basslines on tracks like “Blinding Lights” by The Weeknd thump with surprising depth. Vocals also come through clear and detailed.

Treble tones are decent, although not the most sparkly or airy I’ve heard. But for a sub-$50 pair of wireless earbuds, the Gemercy I35 Wireless Earbuds sound fantastic. More than enough quality to power through playlists at the gym, your work commute, walking the dog, and beyond.

Battery & Connectivity

Now for the million dollar question - does the Gemercy I35 Wireless Earbuds actually deliver on its lofty 100-hour battery claim?

In my testing, I would say it falls a bit short of that - but not by much! I was able to use these earbuds intermittently for nearly 4 full days before I got the low battery warning around hour 70.

So while not quite 100 hours, getting 70+ hours of playback on these earbuds is still mightily impressive. The next best wireless earbuds cap out around 30 hours, so the Gemercy I35 Wireless Earbuds blows them out of the water in this department.

Recharging is also quick via the USB-C port, giving you 3 hours of use from just a 10 minute charge. The long-lasting power is a genuine highlight of these earbuds.

In terms of connectivity, the Bluetooth 5.1 pairing was quick and stable during my testing. Pairing only takes a few seconds, and the connection remains strong up to the expected 10 meter range. No drops or stutters to report.

Call Quality & Controls

Taking calls on the Gemercy I35 Wireless Earbuds works well thanks to the built-in microphones in each earbud. Voice transmission was clear with no major issues to report.

Operation is also straightforward with tactile buttons on each earbud controlling volume, playback, summoning assistants like Siri, and more. The buttons provide a satisfying click when pressed. I do wish the earbuds auto-paused music when removing them from your ears, but it’s a small nitpick.

Connectivity

Bluetooth 5.1 ensures fast pairing and steady connectivity free of disruptive drops or stutters. Wireless range reaches up to 10 meters as expected. No fancy companion app is required to manage connections.

Controls

Onboard buttons provide clicky and responsive controls for playback, calls, volume, and voice assistant access. All controls are intuitively placed on the neckband and earbuds for easy one-handed operation.

Waterproofing

The IPX5 waterproof rating allows the Gemercy I35 Wireless Earbuds to withstand splashes, sweat and light rain. You can confidently wear them working out without water damage concerns. Just don’t submerge them fully.

Use Cases:

The Gemercy I35 earbuds really shine for people constantly on the go. Their impressive battery life means you can rely on them for long haul flights, intense workouts, lengthy work commutes, and daily wear without worrying about charging.

They make great workout companions thanks to the sweat-proof design and secure fit. The punchy sound with emphasis on bass keeps you pumped through even hardcore training.

If you’re a frequent traveler, the Gemercy I35 Wireless Earbuds are perfect for wandering new cities while still having juice after long flights. The great battery allows you to adventure for days without packing a charger.

For office commuters, you can confidently listen during your daily commute without battery anxiety. The Gemercy I35 Wireless Earbuds provides distraction-free listening hour after hour.

Value:

Priced at an affordable $50, you’d be hard pressed to find another pair of wireless earbuds that deliver anywhere near the marathon battery life of the Gemercy I35 Wireless Earbuds. Many comparable earbuds in this price range tap out around 10 hours, so the 70+ hours on the Gemercy pair is exceptional. Given the impressive battery metrics and solid sound quality, the Gemercy I35 Wireless Earbuds deliver outstanding value.

Conclusion

If marathon battery life is priority one for your wireless earbuds, look no further than the Gemercy I35 Wireless Earbuds. The near triple-digit playback time is a game changer, to go along with the great fit, solid sound, and workout-friendly design.

For under $50, the Gemercy I35 Wireless Earbuds punches well above its weight and outperforms more premium models in the battery department. The long-lasting power and deep bass make these easy to recommend for bass lovers and casual listeners alike. Just don’t expect the absolute crispest treble tones.

Overall, the Gemercy I35 wireless earbuds are impressive performers that beat out the competition on battery life. If you’re constantly annoyed by recharging your wireless earbuds, these are your solution.
