If you want long single-charge battery life and a low-latency gaming mode, choose ADVANCED SOUND GROUP Over Ear; if you need the newest Bluetooth version, a charging case that stretches total listening time much further, and a clip-style open-ear fit, choose Micool Open Ear Headphones.
• ADVANCED SOUND GROUP Over Ear — biggest strength: up to 28 hours of battery on one charge, a 50ms low-latency game mode, and a 3-year limited warranty.
• ADVANCED SOUND GROUP Over Ear — biggest trade-off: older Bluetooth 5.2, no charging case in the box, and noise control listed as "None" despite the "noise cancelling" wording in its title.
• Micool Open Ear Headphones — biggest strength: Bluetooth 5.4, active noise cancellation, four microphones, and a charging case that takes total listening time up to a claimed 52 hours.
• Micool Open Ear Headphones — biggest trade-off: only 18 hours per charge on the buds themselves, just a 6-month warranty, and a clip-on open-ear design that simply feels different from a headband.
• Who each pick is for: the ADVANCED SOUND GROUP pair is for someone who hates charging and wants one pair for work, gym and games; the Micool pair is for someone who wants open-ear awareness, a case in their pocket and the latest Bluetooth.
This is a classic on-ear headband design: 30mm dynamic drivers, a 20Hz–20kHz range, and a lightweight build with adjustable silicone ear hooks that sit over the ear rather than inside it. The hooks are the detail that matters most. On-ear headphones normally slide around when you tilt your head; here the silicone hooks are what hold the cups in place during workouts or a commute, which is why the brand positions this as gym and active-use gear as much as desk gear.
Battery is the headline. Up to 28 hours, charged over USB-C, and no charging case to keep track of. For someone who charges once and forgets about it for several days, that is the whole point of buying this pair. There is also a mode switch: 50ms game mode for low-latency audio, 300ms music mode for streaming and audiobooks. Touch controls handle playback, and a built-in mic covers calls. Bluetooth 5.2 connects to iOS, Android and Windows, so it works as a wireless headset for a PC or tablet as easily as for a phone.
Buy it if you want one headphone for everything and you value runtime and a long 3-year limited warranty over trendier specs. Skip it if you specifically want active noise cancellation — noise control is listed as None — or if you want a charging case, because the box contains the headphones, a cable, a protective case and a manual, and the case is a storage case, not a battery.
The Micool pair is a different species of product. These are open-ear, earhook-style buds with a "water-drop" shape, 27mm speakers, and sponge earcups that rest against the ear instead of sealing over it. The cups are only 36mm across, so the emphasis is on being small and light with no sense of restraint. If you have ever found headbands clamping or in-ears plugging up your ears, this is the shape that solves that problem — you keep ambient sound in, which is exactly what runners and cyclists tend to want.
On the tech side it runs Bluetooth 5.4, the newest version in this comparison, and the brand pairs it with ANC plus ENC adaptive noise reduction and four microphones, so calls get noise suppression and clearer voice pickup. There is a multifunction button on each earpiece for music and calls, so you are not reaching for a phone mid-run.
The battery story is split in two. The buds alone give up to 18 hours per full charge; with the charging case topped up, total listening time is claimed at up to 52 hours. The case has a four-stage power indicator — each light is 25% — and charges over USB-C. That case is genuinely useful, but note the trade-offs: 18 hours is less than the ADVANCED SOUND GROUP pair on a single charge, and the warranty is 6 months rather than 3 years. Buy it if you want open-ear awareness, a pocketable case and the latest Bluetooth. Skip it if you want maximum runtime per charge or a longer warranty.

My Verdict
how to put wireless headphones in pairing mode
The exact button sequence varies by brand, and neither data sheet spells out the steps, so follow the user manual that ships in the box. Both models pair over Bluetooth — the ADVANCED SOUND GROUP pair on Bluetooth 5.2 and the Micool pair on Bluetooth 5.4 — and the Micool earpieces each carry a multifunction button that handles controls. If pairing stalls, the usual fix is to make sure the headphones are charged first.
how connect bluetooth headphones to phone
Turn the headphones on, put them into pairing mode, then open your phone's Bluetooth menu and select the headphone from the list of available devices. The ADVANCED SOUND GROUP pair lists iOS and Android compatibility, so it works with either phone platform, and the Micool pair uses Bluetooth 5.4, which the brand says pairs quickly and holds a more stable connection. Once paired, the phone remembers the device and reconnects automatically next time.
how do wireless bluetooth headphones work
They receive audio over a short-range Bluetooth radio link from your phone, tablet or computer — there is no headphone jack on either model here. The ADVANCED SOUND GROUP pair uses 30mm dynamic drivers covering 20Hz–20kHz, while the Micool pair uses 27mm speakers with ANC and ENC noise reduction for calls. Battery powers the whole chain, which is why runtime matters: up to 28 hours on the ADVANCED SOUND GROUP pair versus up to 18 hours per charge plus a charging case on the Micool pair.
how to connect sony wh ch520 on ear wireless bluetooth headphones
That is a different brand's on-ear model and it is not covered by either data sheet here, so I cannot give model-specific steps for it. The general method is the same for any Bluetooth headphone: charge it, hold the power or pairing button until the indicator flashes, then select it in your phone's Bluetooth settings. If you are comparing on-ear options, the ADVANCED SOUND GROUP pair is the on-ear design in this article, while the Micool pair is an open-ear clip-on.
