If you want open-ear earbuds with a fit designed to avoid a tight seal, choose Monster Open Ear AC336; if you need two listening styles in one set, choose PAXA 2. For big head comfort, the more important question is how each earbud’s hook or clip sits on your ears, not a headband size neither product has. My pick is Monster for straightforward open-ear listening; PAXA makes more sense if switching to in-ear audio is a priority.
• Monster Open Ear AC336: A single open-ear style with touch controls, Bluetooth 6.0, and up to 21 hours of total playback; its main trade-off is that it does not switch to an in-ear option.
• PAXA 2: Includes clip-on open-ear earbuds and a separate in-ear pair in one set; its main trade-off is the extra choice and gear to manage, plus a longer stated initial charging requirement.
• For big head comfort: Neither has a headband to fit or adjust, so fit depends on how the ear pieces sit on your ears.
• Choose Monster for one open-ear setup with a short-charge feature and IPX6 water resistance.
• Choose PAXA if you want to alternate between awareness-oriented open-ear listening and a more private in-ear style.
Monster’s main appeal is a single open-ear design that does not create a tight seal in the ear canal. That may suit someone who dislikes the plugged-in feeling of conventional earbuds or wants to keep more awareness of nearby sounds while listening. The hook-shaped earpiece and shape-memory hardshell material are intended to hold the earbuds in place, though fit will still vary with individual ears.
The feature set is straightforward: Bluetooth 6.0, touch control, ENC for calls, and up to seven hours of playback on one charge at the stated listening level. The case brings total playback to up to 21 hours, and the Type-C fast-charge feature is specified to provide an hour of playback after 10 minutes of charging. That is useful if you tend to forget to charge overnight and need a quick top-up.

PAXA’s defining feature is its two-style setup: one pair of clip-on open-ear earbuds and one pair of in-ear earbuds, all supplied with a single charging case. The open-ear pair is meant for situations where awareness of the surroundings matters. The in-ear pair offers a more enclosed listening option for work, study, or places where you want to limit sound leakage. Switching styles gives PAXA a flexibility Monster does not offer.
The set uses Bluetooth 6.0 and touch controls, and PAXA describes the in-ear option as using directional sound transmission to help limit leakage. It lists IPX5 water resistance and up to 24 hours of use from the case. The much larger 140-hour figure is described as standby time for the two pairs combined, not continuous playback. The stated first full charge is six to eight hours, so this is not the set I’d choose when a quick first setup is important.
PAXA may be worth considering if you often move between a walk, a shared workspace, and focused listening. Its clip-on style also makes it a candidate for someone searching for wireless clip on earbuds for big head, but the supplied details do not establish a larger fit range or guarantee comfort for every ear shape. If you want one open-ear pair with fewer switching decisions, Monster is simpler.
• Best for one consistent open-ear setup → Monster Open Ear AC336. Its design avoids a tight ear-canal seal, and there is no second style to switch in and out.
• Best for two listening styles → PAXA 2. You get clip-on open-ear earbuds and a separate in-ear pair in the same set.
• Best stated short-charge convenience → Monster Open Ear AC336. Its listed 10-minute charge is associated with up to one hour of playback; PAXA specifies a six-to-eight-hour first full charge.
• Best for the higher stated case playback figure → PAXA 2. It lists up to 24 hours of use, compared with Monster’s up to 21 hours total. These are manufacturer figures, not a guarantee of identical listening conditions.
• Best for a workout where water resistance matters → Monster Open Ear AC336. It specifies IPX6, while PAXA specifies IPX5. Neither rating means the earbuds are suitable for every kind of water exposure.
• Best if limiting sound leakage is a priority → PAXA 2. Its in-ear option is described as using directional sound transmission to resist leakage; Monster is an open-ear design.
• Best for a big-head shopper seeking a headset fit → Neither is a headband headset. Both use ear-mounted designs, so the practical fit question is whether the hook or clip feels secure on your ears.
• Best if you want an extra bass kids headset for big head → Neither can be confidently identified from the supplied specifications. They are adult earbud sets, and no bass tuning or child-specific fit information is provided.
My Verdict
In my opinion, I’d choose Monster Open Ear AC336 for big head comfort when the goal is an open-ear style without a tight canal seal. Its single design is easy to understand, and its short-charge feature is a useful practical advantage.
I’d choose PAXA 2 instead if I regularly needed both open-ear awareness and a more private in-ear option.
Neither product uses a headband, so “big head” does not translate into a headset size here. Both rely on ear-mounted designs; comfort and security will depend on how their hooks or clips fit your ears.
Yes. The set includes a pair of clip-on open-ear earbuds and a pair of in-ear earbuds, with one charging case. That gives you two listening styles, rather than two separate headband headphones.
Monster lists up to 21 hours of total playback, including the case. PAXA lists up to 24 hours of use and separately describes up to 140 hours of combined standby time for the two pairs; standby is not the same as continuous playback.
Monster lists ENC for calls and IPX6 water resistance. PAXA lists hybrid noise reduction and IPX5 water resistance, but the supplied details do not give a directly comparable call-performance result. For outdoor use, consider the stated water-resistance ratings and whether you prefer open-ear awareness or an in-ear option.
