Getting Started with Your Thinkplus Earbuds
The manual for Thinkplus Earbuds is basically a reference document that explains pairing, charging, and basic troubleshooting. Most people don't actually need it if they just want to use the earbuds day to day, but there are a few settings buried in there that aren't obvious without reading something. I keep a PDF version on my phone for when one of the two earbuds stops responding randomly and I need to reset it quickly. The official manual is available from the Lenovo or ThinkPlus website. Search for "Thinkplus Earbuds manual PDF" and you should find the direct download on their support page. Some third-party sites host it too, but the Lenovo one is the one I trust since firmware notes sometimes change between revisions. Download it and save it somewhere you can reach it offline. My copy has been sitting in my downloads folder for about eight months. Pairing is straightforward. Open the case, hold the button on the back for three seconds until the LED flashes white, then grab your phone and connect through Bluetooth. That part takes about twenty seconds. What most people miss is that the manual mentions a double-tap gesture customization if you download the Lenovo Smart Life app. Without the app, you're stuck with factory defaults—single tap for play/pause, double for call answer, triple for voice assistant. If your taps feel unresponsive, check that the firmware hasn't updated recently. A firmware update changed my double-tap sensitivity on a pair I bought last year and I had to go back into the app to recalibrate it.
Charging is magnetic alignment inside the case. The contacts are small and align properly when you hear a soft click. I learned the hard way that forcing them in crooked doesn't damage anything, but it does cause intermittent charging failures. I had one bud that would show 40 percent battery one minute and then drop to zero the next because the charging contact wasn't making solid connection. Wiping the gold pads with a microfiber cloth and a tiny bit of isopropyl alcohol fixed it permanently. There are some issues worth noting before you get too comfortable with these. The active noise cancellation mode is decent for office noise but completely ineffective against low-frequency rumble like engine sounds. If you're buying these for a commute on a bus or train, you'll be disappointed. The transparency mode also has a noticeable lag of about half a second, which makes conversations feel delayed. It's not a dealbreaker, but it's something to be aware of if ANC is a primary reason you're considering them. Battery life claims around eight hours with ANC off are accurate in my testing, but turn on ANC and you're looking at roughly five and a half to six hours depending on volume level. The case gives you two full charges, so your real-world total is closer to fifteen hours, not the twenty-four the box implies. That math matters if you're traveling and planning to use them all day without access to a wall outlet.
If the earbuds refuse to pair after a reset, try forgetting the device from your phone's Bluetooth list first, then power cycle the earbuds by placing them back in the case and closing the lid for ten seconds. Opening it again and holding the button will restart the pairing sequence. This solved a problem I had where my laptop kept rejecting the connection while my phone paired fine. It turned out the laptop was holding onto a stale pairing key. Clearing it on both sides fixed it immediately. The microphone quality is acceptable for phone calls in quiet environments but picks up wind noise aggressively. I use these for work calls from my desk and the quality is fine, but outside in anything with a breeze the other person will hear it. I've switched to using my phone's built-in mic for outdoor calls instead of routing through the earbuds, which helps noticeably. I don't have anything negative to say about the build quality for the price point. They feel lightweight without feeling cheap, and the case has held up well over several months of daily carry in a pocket. The only wear I've seen is minor scuffing on the case hinges after about six months. Everything else looks the same as when I first opened the box.

If you need the manual for a specific firmware version or regional variant, check the part number on the inside of the charging case. It's usually printed in small text near the USB-C port. That number matters because different regions sometimes ship with slightly different default button mappings. The manual PDF on the Lenovo site lets you filter by region, so make sure you grab the right one or you might be confused about which gesture does what.
