If you want longer stated listening time with ANC and a lighter over-ear option for library study, choose OneOdio Focus A5; if you need stronger stated ANC depth and dual-mic call noise reduction, choose OneOdio Focus A6. For library use, I’d lean toward the A5 because its listed 45-hour ANC playback gives it an edge for long stretches of focused listening.
• OneOdio Focus A5: Its biggest strength is the stated 45 hours of playback with ANC enabled, plus LDAC support and a low-latency game mode. Its trade-off is that its listed ANC depth is -45dB, slightly less than the A6’s figure.
• OneOdio Focus A6: Its biggest strengths are the stated -48dB ANC depth, dual-mic ENC for calls, and USB-C wired ANC support. Its trade-off is 40 hours of stated playback with ANC on, five hours less than the A5.
• Both are over-ear wireless headphones with LDAC, a stated maximum of 75 hours of Bluetooth playback, and 10-minute charging claims of 10 hours of playtime.
• Choose the A5 for library sessions where long ANC runtime and low-latency game mode matter; choose the A6 if call clarity, wired ANC, and its stronger stated ANC depth fit your routine.
The Focus A5 is an over-ear wireless headphone built around hybrid active noise cancellation, LDAC audio support, and long stated battery life. Its listed playback reaches 75 hours in Bluetooth mode or 45 hours with ANC on. That 45-hour figure is the useful distinction for someone who expects to keep noise cancellation active through long study sessions, commutes, or travel.

Skip the A5 if your main priority is the A6’s listed ANC depth, dual-mic ENC call feature, or USB-C wired ANC support. The A5’s facts point more clearly toward extended ANC listening and everyday audio use than toward call-focused features.
The Focus A6 is also an over-ear wireless headphone with hybrid ANC and LDAC support. Its listed ANC depth reaches -48dB, compared with -45dB for the A5. Those figures give the A6 the stronger stated noise-cancellation specification, though they do not tell the whole story of how either model will sound or feel in a particular room.
The A6 is the better fit on paper for someone who takes calls as well as listens. It has a dual-mic ENC system intended to reduce background noise during calls, and it supports wired ANC through USB-C. That wired option could matter if you want to listen through a cable while keeping ANC available. Bluetooth 6.0 is listed for the A6, while the A5 lists Bluetooth 5.4.
The trade-off is its stated 40 hours of playback with ANC enabled, five hours fewer than the A5’s 45-hour figure. It is also listed at 295 g. If you mainly want long ANC listening for quiet work, the A5’s battery figures may be more compelling; if call features and wired ANC matter more, the A6 has the clearer case.
• Best for longer stated ANC playback → OneOdio Focus A5. It lists up to 45 hours with ANC on; the A6 lists up to 40 hours.
• Best for stronger stated ANC depth → OneOdio Focus A6. Its specification reaches -48dB, versus -45dB for the A5.
• Best for calls and remote meetings → OneOdio Focus A6. Its dual-mic ENC feature is specifically described for reducing background noise during calls.
• Best for listening with wired ANC → OneOdio Focus A6. Its USB-C connection supports wired audio and ANC.
• Best for a lighter listed weight → OneOdio Focus A5. At 265 g, it is 30 g lighter than the A6’s listed 295 g.
• Best for low-latency mobile gaming → OneOdio Focus A5. Its game mode is listed at approximately 0.065 seconds of latency.
• Best for Bluetooth version → OneOdio Focus A6. It lists Bluetooth 6.0, while the A5 lists Bluetooth 5.4.
• Best for battery life without ANC → Tie on the stated figure. Both list up to 75 hours of Bluetooth playback, so this specification alone does not separate them.
For a library, neither model is described as an open-ear or clip-on design. Both are over-ear headphones, so shoppers specifically looking for bluetooth clip on earbuds for library use or touch control open ear earbuds for library use should treat these as a different style of product. If you are comparing on ear headphones for library sessions, note that both Focus models are listed as over-ear instead.
I’d choose the OneOdio Focus A5 for my library listening setup. Its 45-hour stated ANC runtime, lighter listed weight, LDAC support, and game mode make it the more rounded fit for long listening stretches.
I’d switch to the A6 if I took frequent calls, wanted USB-C wired ANC, or valued its stronger stated ANC depth more than those differences.
For library use, my pick is the A5 because its longer ANC playback is the clearest practical advantage for extended focus.
For long listening sessions with ANC enabled, the A5 has the stronger battery specification: 45 hours, versus 40 for the A6. The A6 lists a greater ANC depth and adds dual-mic call noise reduction, which may suit a library user who also takes calls.
The A6 lists ANC depth of up to -48dB, while the A5 lists up to -45dB. These are manufacturer-stated specifications, not a direct measure of how much noise every listener will perceive in every setting.
The A6’s listed features include wired audio and ANC via USB-C. Its included USB-C cable is described as supporting audio and charging.
The A6 is the more call-oriented choice on the stated features because it includes dual-mic ENC for call noise reduction. The A5 lists clear calls among its capabilities, but does not specify the same dual-mic ENC feature.
