What's the difference between this and the life 2?

Compared with Life 2, the Life Q20 better/greatly reduces ambient noises by adopting Hybrid Active Noise Canceling technology and adding 2 more (4 in total) built-in ANC microphones. Also, our engineers fine-tuned the sound and speaker to bring our customers a more enjoyable listening experience.

Does using the aux cable work, if the headphones aren't charged? I have a set where this doesn't work, so it is a legitimate question.

They've changed how this product works between 2019 and now, clearly. The newer editions of this model do NOT have ANC while in AUX mode, which is absolutely ridiculous. Current user manual for this edition states: "Plugging in an audio cable will automatically switch to AUX mode, and Bluetooth mode and ANC will turn off". While old one posted in another answer states ANC will operate while in AUX mode. Definitely returning these now.

They use internal and external microphones to cancel out the ambient sound. it relies on microphones to seek out ambient noises and then cancel them out. But where it’s common for most active noise-canceling headphone designs opt to place microphones solely on the outside or solely on the inside of the earcups, hybrid noise-canceling headphones have both. Generally, active noise-canceling headphones with internal microphones tend to sound great, but have less-than-optimal noise-cancellation powers. This is because the microphones hear when the listener hears (since the mics are on the inside), and they know exactly what sounds to block out without polluting the actual music that is attempting to reach your ears. Unfortunately, this approach typically can’t handle louder noises and higher frequencies, however, so the noise-cancellation isn’t as good. With active noise-canceling headphones that have external microphones, the opposite is true. Since the mics are on the outside, they tend to block out a wider range of frequencies and can do better with generally louder sounds. The downside is that they typically create more “anti-noise” and this can negatively impact sound quality.

Does it have aux input

Yes, you can use it in wired mode since the headphones come with an AUX cable. We can use the headphones in two ways--- in bluetooth mode or in wired mode(with an AUX cable).
