If you want lightweight clip-on earbuds with longer stated total playback and a laptop connection option, choose LIUP Open-Ear Earbuds; if you need adjustable earbud positioning, stronger stated water resistance, and app-based EQ presets for PC listening, choose TOZO O2. For a PC setup where you want your ears uncovered, I give LIUP the narrow overall edge, while TOZO O2 is the more adjustable, weather-ready alternative.
• LIUP Open-Ear Earbuds: A 4.8 g-per-earbud clip-on design, three ear-tip sizes, Bluetooth 5.4, and up to 48 hours of stated total playtime; the trade-off is IPX4 water resistance and no listed EQ app.
• TOZO O2: A dual-axis adjustable fit, IPX6 water resistance, a 14.2 mm dynamic driver, and five app EQ presets; the trade-off is up to 42 hours of stated total playtime and Bluetooth 5.3.
• Both offer open-ear listening, dual-device connectivity, and call noise-reduction features, but neither sheet specifies PC-focused spatial audio.
• Choose LIUP for a lighter clip-on format, more stated case-inclusive playback, and a listed phone-and-laptop connection use case.
• Choose TOZO O2 if physical angle adjustment, stronger water resistance, and app sound customization matter more.
LIUP Open-Ear Earbuds: Who It's For
LIUP’s defining idea is a clip-on, open-ear fit built around a silicone C-bridge and interchangeable S, M, and L ear tips. Each earbud is listed at 4.8 g. That combination points toward someone who wants audio without sealing the ear canal, but also wants a more supported-feeling fit than a loose earbud shape may suggest. LIUP specifies 8 hours per charge and up to 48 hours when including the case.
LIUP makes sense for people who want a light open-ear clip-on for computer sessions, commuting, or workouts, especially if choosing among three tip sizes is useful. It is also the more plausible pick for someone searching for the best neckband headphones for PC only in the broad sense of wanting hands-free, open-ear listening; however, this is a true wireless clip-on design, not a neckband. Skip it if IPX6-level water resistance or adjustable hinge positioning is a priority: LIUP lists IPX4, and its sheet does not describe a dual-axis adjustment mechanism.
TOZO O2 is also open-ear, but its main fit feature is a dual-axis design that lets the wearer adjust the earbuds horizontally and vertically. That gives the product a distinct practical angle for people whose comfort depends on positioning the speaker rather than selecting another ear-tip size.
For a PC listener, O2 combines dual-device connectivity with TOZO app support and five preset EQ options. The sheet also says either earbud can be used independently, which may help when a listener wants a single earbud in use. Its 14.2 mm dynamic driver is larger by the stated measurement than LIUP’s 10 mm driver, but driver size alone does not prove that one sounds better. The listed Bluetooth version is 5.3, and the frequency range is 20 Hz–20,000 Hz.
O2 is a reasonable fit for someone who wants to tune sound through presets, adjust the earbud angle, or choose the model with IPX6 water resistance. Its call noise-cancellation feature is specified as DSP-based, and it is designed for calls in noisy surroundings, though the sheet does not provide independent test results. If you are looking for the best spatial audio sleep headphones for PC, neither product sheet establishes spatial audio or a sleep-specific design. These are open-ear earbuds intended for everyday use, work, and activity—not a documented spatial-audio or sleep-headphone solution.

Side-by-Side: Which Should You Choose?
• Best for stated total battery life → LIUP Open-Ear Earbuds. LIUP lists up to 48 hours with the case; TOZO O2 lists up to 42 hours.
• Best for longer stated single-charge playback → TOZO O2. It lists up to 12 hours per charge, compared with LIUP’s 8 hours.
• Best for a laptop-and-phone connection use case → LIUP Open-Ear Earbuds. Its details explicitly mention simultaneous connection to a phone and laptop. Both products list dual-device connectivity, though TOZO describes connecting two phones.
• Best for adjustable wearing angle → TOZO O2. Its dual-axis design supports horizontal and vertical adjustment; LIUP instead provides three ear-tip sizes.
• Best for stronger listed water resistance → TOZO O2. It specifies IPX6, while LIUP specifies IPX4.
• Best for a lighter stated earbud weight → LIUP Open-Ear Earbuds. The sheet gives a per-earbud figure of 4.8 g; no corresponding TOZO O2 weight is provided, so this is not a direct measured comparison.
• Best for app-based sound presets → TOZO O2. It supports five preset EQ settings through the TOZO app; LIUP does not list app EQ.
• Best for a kids headset for PC search → neither is specifically established as a kids headset. Both are described for adult or general use, and neither sheet provides child sizing or a child-specific fit feature. For a child, fit should be assessed carefully rather than inferred from general fit claims.
In my opinion, I would choose LIUP Open-Ear Earbuds for a PC setup because its listed dual connection explicitly includes a laptop, its stated total playback is longer, and its lightweight clip-on design offers three tip sizes.
That is a narrow preference, not a claim that it sounds better.
I would choose TOZO O2 instead if adjustable positioning, IPX6 resistance, or app EQ presets are more important to you.
For PC use, LIUP is my pick when the priority is practical open-ear listening across a computer and phone.
LIUP’s product details specifically describe simultaneous connections to a phone and laptop, which makes its PC use case especially clear. TOZO O2 also supports dual-device connectivity, but its sheet describes two phones rather than naming a computer.
LIUP lists up to 48 hours total with the charging case, while TOZO O2 lists up to 42 hours. TOZO O2 lists the longer single-charge figure: up to 12 hours, compared with LIUP’s 8 hours.
Both sheets describe DSP call noise reduction, with claims of reducing up to 90% of background noise during calls. That refers to call noise handling; neither product sheet establishes active noise cancellation for blocking what the wearer hears.

For PC use, the practical hook is dual-device connectivity: the product information says it can connect to a phone and laptop at the same time. That could suit someone who listens to a computer but wants a phone paired too, rather than repeatedly setting up a connection. Bluetooth 5.4 is specified, along with touch controls and a stated five-minute quick charge that provides one hour of playback. The 10 mm dynamic drivers and 20 Hz–20,000 Hz listed frequency range describe the hardware, but they do not establish a particular sound signature beyond the manufacturer’s claims.

My Verdict
That is a narrow preference, not a claim that it sounds better.
I would choose TOZO O2 instead if adjustable positioning, IPX6 resistance, or app EQ presets are more important to you.
For PC use, LIUP is my pick when the priority is practical open-ear listening across a computer and phone.
LIUP’s product details specifically describe simultaneous connections to a phone and laptop, which makes its PC use case especially clear. TOZO O2 also supports dual-device connectivity, but its sheet describes two phones rather than naming a computer.
LIUP lists up to 48 hours total with the charging case, while TOZO O2 lists up to 42 hours. TOZO O2 lists the longer single-charge figure: up to 12 hours, compared with LIUP’s 8 hours.
Both sheets describe DSP call noise reduction, with claims of reducing up to 90% of background noise during calls. That refers to call noise handling; neither product sheet establishes active noise cancellation for blocking what the wearer hears.
TOZO O2 lists IPX6 water resistance, while LIUP lists IPX4. Based on those specifications, TOZO O2 is the stronger choice for water resistance, though neither rating by itself describes every possible exposure or use condition.
