The TOZO A1 is the more portable option, with a charging case, call-focused microphones, and a very light design. But it is an in-ear earbud—not a large-head headphone—and it has no noise-control feature.
Soundcore Anker Space One vs TOZO A1 at a Glance
• Soundcore Anker Space One: Over-ear headphones with adaptive active noise cancellation, LDAC support, and up to 40 hours of listening with ANC on. Trade-off: the over-ear design is less compact than small earbuds, and the listed specs do not state a headband size range.
• TOZO A1: Compact earbuds weighing 3.7 grams each, with two microphones for calls, an app with 32 EQ presets, and up to 32 hours total playtime with the case. Trade-off: there is no active noise cancellation, and an in-ear fit may not suit listeners who want headphones around the ear.
• Choose Soundcore if you want over-ear listening, adaptive noise cancellation, and longer playback between charges.
• Choose TOZO if you want a small earbud-and-case setup, call microphones, and water resistance for everyday wear.
The Soundcore Anker Space One is the clearer fit if your priority is wearing headphones over your ears rather than placing earbuds inside them. Its adaptive active noise cancellation detects external sound and sound leakage, then adjusts its noise reduction. That feature is aimed at distracting environments such as a train or café, where simply turning up the volume may not be what you want. The headphones also support LDAC audio through 40 mm dynamic drivers.

For someone searching for the best gaming headphones for big head, the Space One is the more relevant style of the two because it has an over-ear design. Still, the supplied specifications do not give a headband adjustment range or establish that it fits every large head comfortably. I would not treat its shape alone as a guarantee of fit. Skip it if you specifically want tiny earbuds, or if your main need is a stated water-resistance rating; one is not provided here.
The TOZO A1 takes the opposite approach: small, lightweight earbuds that sit in the ears and come with a charging case. Each earbud weighs 3.7 grams, and the product is described as having a compact design intended for small ears. That could appeal to someone who dislikes carrying full-size headphones or wants a low-profile option for everyday listening. Its case adds up to 32 hours of total playback, while the earbuds provide up to seven hours on a charge.
For calls, the A1 has two microphones and ENC intended to reduce background noise such as office or traffic sounds. It also offers 32 EQ presets through the TOZO app, giving listeners a way to adjust the sound profile. Bluetooth 5.3 and a stated 20-meter Bluetooth range round out its wireless features. These specifications make it a practical choice for calls, podcasts, and routine listening—not a replacement for over-ear noise cancellation.
The A1 is listed as IPX5 waterproof, but that does not make it the best IPX7 waterproof neckband headphones for big head: it is neither rated IPX7 in the supplied information nor a neckband design. It is also not a pair of with mic open ear headphones for big head; it is an in-ear model with microphones. Choose it for portability and a light earbud form, but look elsewhere if you need an over-ear fit, an open-ear design, a neckband, or active noise cancellation.
• Best for over-ear listening → Soundcore Anker Space One. It goes around the ears, while the TOZO A1 sits inside them.
• Best for adaptive active noise cancellation → Soundcore Anker Space One. The A1’s listed noise control is none, though its microphones use ENC for calls.
• Best for longer playback without relying on a case → Soundcore Anker Space One. Its stated figures are up to 40 hours with ANC on or 55 hours with ANC off.
• Best for carrying in a pocket or small bag → TOZO A1. The earbuds come with a compact charging case; the Soundcore is an over-ear set and includes a headphone case.
• Best for calls in everyday background noise → TOZO A1. It has two microphones and ENC designed to help reduce background noise on calls.
• Best for changing EQ through a companion app → TOZO A1. Its app offers 32 EQ presets; the Soundcore’s listed app feature is control, without a stated preset count.
• Best for a large-head buyer choosing between these two designs → Soundcore Anker Space One, with a fit caveat. It is the only over-ear option, but the provided information does not specify headband dimensions.
• Best for a water-resistance rating → TOZO A1. It is listed as IPX5 waterproof; the Soundcore sheet does not provide a water-resistance rating.
My Verdict
I would choose the Soundcore Anker Space One for a big-head use case because its over-ear design is a closer match than small in-ear earbuds, and its adaptive ANC and extended playback suit longer listening sessions. That is a design-based preference, not a guarantee of fit: the specs do not state its headband range.
The Space One is the more relevant choice because it is an over-ear headphone; the A1 is a compact in-ear earbud. The listed information does not give the Space One’s headband dimensions, so it cannot confirm fit for every big head.
The A1 is listed with no noise-control feature. It does have ENC microphones intended to help reduce background noise during calls, which is different from active noise cancellation for listening.
The Space One is listed for up to 40 hours with ANC on and up to 55 hours with ANC off. The TOZO A1 offers up to seven hours per charge and up to 32 hours total when using its charging case.
The A1 is listed as IPX5 waterproof and is described as suitable for workouts and everyday wear. The supplied information does not provide a water-resistance rating for the Space One.
