As usual, the Soundcore comes with three sizes of ear tips: small, medium, and large. The medium size fits my ears perfectly. I strongly advise you to select the size that best fits your ears. These have an impact on sound quality and noise cancellation because they are close-fitting in the ear shape and are difficult to fall out of. The charging case has a sturdy lid and high-quality materials. Their size is normal, neither too large nor too small. On the front of the case, an LED light indicates how much power is left in the case. The LED light is normally white, but it turns red when it loses more than 10% of its power. The Anker Soundcore Life P3i has a battery life comparable to the Life A3i, with earbuds lasting 9 hours and the charging case lasting approximately 27 hours. The total time is 36 hours. The Life P3i wireless earbuds provide approximately 6 to 9 hours of battery life once fully charged. Depending on the volume level and whether the ANC feature is turned on or off. Single earbuds, on the other hand, can be used separately. That means that if you only use one earbud, you can get up to 12 to 18 hours of playtime. That is sufficient for a long flight across the continent. Unfortunately, wireless charging is not supported by the charging case. It does, however, support USB-C charging, which includes a fast charging feature. You can get an extra 2 hours of playtime by charging for only 10 minutes. That is also true for the Life A3i. The factory default controls were confusing. Nonetheless, the Anker Life P3i supports the SoundCore app, allowing you to easily change all controls through the app. There is a seamless button on the top of the stems that has a neat little sound click when pushed. In terms of the connection. The Anker Soundcore Life P3i provides a strong and stable performance. When taking the earbuds out of the case, they are simple to pair and connect. Bluetooth 5.2 provides a stable connection up to 10 meters away. This means you can move away from your Bluetooth devices within this range.
