Adaptive ANC vs Active ANC Specs
noise cancellation type
The Soundcore P31i uses Real-Time Adaptive Noise Cancelling. This system detects your surroundings and automatically adjusts the noise-cancelling level. It reduces noise by up to 52 dB. You do not need to change settings manually. The TOZO NC9 uses Hybrid Active Noise Cancelling. It offers a fixed maximum noise reduction depth of 45 dB. This mode is designed to block outside distractions without automatic adjustments. If you want the earbuds to choose the best level for you, the Soundcore P31i is the better choice. Its adaptive technology handles the changes for you. The TOZO NC9 requires you to rely on its fixed hybrid setup.
battery life
Battery performance differs significantly between these two models. The Soundcore P31i provides up to 10 hours of playtime on a single charge. The case adds 40 hours, totaling 50 hours. With ANC active, you get 8 hours per charge and 40 hours total. The TOZO NC9 offers more total playtime. You get 14 hours on a single charge with ANC off. The case provides 46 additional hours, totaling 60 hours. With ANC on, the single charge lasts 10 hours, and the total is 40 hours. For maximum total battery life, the TOZO NC9 wins. For longer single-charge listening without ANC, the TOZO NC9 also leads. The Soundcore P31i is more efficient with ANC on for single charges.
microphone setup
Call quality depends on the microphone configuration. The Soundcore P31i features six AI-enhanced microphones. These work with an AI noise reduction algorithm to separate your voice from background noise. It also includes a wind-noise reduction algorithm for clear calls outdoors. The TOZO NC9 uses a six-microphone setup with ENC Ambient Noise Reduction. This actively filters out background sounds for crystal clear calls. Both products use six microphones to improve call clarity. The Soundcore P31i highlights wind noise reduction specifically. The TOZO NC9 mentions ambient noise reduction generally. Both provide robust solutions for noisy environments. This results in a tie for microphone performance based on the available data.
audio features
Audio capabilities vary between the two earbuds. The Soundcore P31i is Hi-Res Certified and supports LDAC. This allows for lossless Hi-Fi audio with rich, well-balanced treble and bass. It reproduces musical nuances effectively. The TOZO NC9 features 10mm drivers and OrigX Acoustic 2.0 technology. This delivers deep, rich bass and precise audio clarity. It also offers 32 EQ options via the TOZO app. You can adjust bass levels and music styles. The Soundcore P31i offers superior audio fidelity through LDAC and Hi-Res certification. The TOZO NC9 offers more customization through its EQ app. For pure sound quality, the Soundcore P31i has the advantage.
water resistance
Durability in wet conditions is a key spec. The TOZO NC9 carries an IPX8 water resistance rating. This allows it to withstand sweat, rain, and accidental splashes. It is suitable for active outdoor lifestyles. The Soundcore P31i data does not list a water resistance rating. Without this information, you cannot assume it has similar protection. The TOZO NC9 is the safer choice for exercise or rain. Its IPX8 rating provides a clear advantage for users who need reliable water protection. The Soundcore P31i lacks this specified durability feature in the provided data.
