If you want two pairs, active noise cancellation, and a white in-ear set you can share or stash as a backup, choose ALIANSHENG 2; if you need a single black pair with a metal-plated plug, strengthened cord, and inline volume controls, choose Flecom USB C Earbuds.
• ALIANSHENG 2 — biggest strength: You get two pairs in one box, plus active noise cancellation and a 24-month replacement warranty.
• ALIANSHENG 2 — biggest trade-off: It's a plastic, white in-ear design with no inline volume buttons listed, and you can't buy just one.
• Flecom USB C Earbuds — biggest strength: Built-in volume control with track and call buttons on the cord, plus metal-plated connectors and a strengthened wire.
• Flecom USB C Earbuds — biggest trade-off: It's a single pair, relies on passive sound isolation rather than active noise cancellation, and the earpieces are a combination of materials rather than a simple all-plastic shell.
• Who each pick is for: ALIANSHENG 2 suits people who want a spare pair and real noise cancelling; Flecom suits people who want one durable pair with hands-on volume control.
The headline feature here is simple: this is a 2-pack. Two identical USB-C wired earbuds in the box. That single detail changes how you use them. One pair can live in your bag, the other at your desk. One for you, one for a partner or a kid. If you're the kind of person who loses earbuds constantly, having a spare already in the drawer is genuinely useful.
The audio side is built around a digital DAC chip that converts standard-resolution audio into what the spec sheet calls superior lossless audio. It's a wired USB-C connection, so there's no battery to charge and no pairing to fiddle with — plug in and go. The driver is a dynamic driver with a 20 Hz to 20,000 Hz frequency range and 32 ohm impedance, which is a normal, easy-to-drive spec for a phone or tablet. It also lists active noise cancellation, controlled remotely, which is unusual at this tier and is the feature that separates it most clearly from the Flecom set.
Comfort-wise, the shape is an ergonomic in-ear with rounded tips, and the pitch is about reducing fatigue over long listening sessions. The cable is described as easy to roll up without tangling. Realistically, that's the commuting, bus, running, gym and walking-around use case — the stuff where a wire is actually an advantage because it never dies mid-trip. The 24-month replacement warranty is also notably longer than the Flecom's 1-year coverage, which matters if you're hard on cables.
Who should buy it: anyone who wants a spare pair on hand, wants active noise cancellation on a wired set, or wants the longer warranty. Who should skip it: if you only ever need one pair, or you specifically want volume buttons on the cord, this isn't the one — nothing in the spec sheet lists inline volume control, and you're paying for a second set you may not use.
Flecom's angle is durability and control. The cord is strengthened for longer life, and the connectors are metal-plated, which the sheet ties to reducing poor contact over time. If you've had cheap wired earbuds die at the plug, that's the failure point being addressed here. The cable runs 1 meter, which is a sensible length for a phone in a pocket or a laptop on a desk.
The control set is the real differentiator: volume up/down, previous/next track, pause, and answer/end/reject call — all on the remote. That's full hands-free operation while driving, walking, exercising, working or shopping. If you take a lot of calls on wired earbuds, having call control right there on the cord is more useful than it sounds.
Inside, there's again a built-in DAC chip, this time pitched at maintaining high-resolution acoustics without buzzing, popping or other artifacts — plug and play. The driver is a dynamic driver with the same 20 Hz to 20,000 Hz range as the ALIANSHENG. Noise control is listed as sound isolation, meaning passive blocking from the in-ear seal rather than active cancellation. The earpieces are a combination of materials in black, and it's sold as a single pair.
Who should buy it: someone who wants one solid pair, values physical volume buttons, and likes the idea of a reinforced cord and plated plug. Who should skip it: if you want active noise cancellation, a spare pair in the box, or the longer warranty, the ALIANSHENG set fits better.
• Best for getting a spare pair → ALIANSHENG 2 (it ships as a 2-pack; Flecom is 1 pack).
• Best for active noise cancellation → ALIANSHENG 2 (listed as Active Noise Cancellation; Flecom lists sound isolation).
• Best for on-cord volume control → Flecom USB C Earbuds (volume +/-, track skip, pause, call answer/end/reject).
• Best for cable and plug durability → Flecom USB C Earbuds (strengthened wire, metal-plated connectors).
• Best for warranty length → ALIANSHENG 2 (24-month replacement vs. 1-year).
• Best for a discreet, single black set → Flecom USB C Earbuds (black, combination-of-materials shell).
• Best for sharing or traveling with a backup → ALIANSHENG 2 (white, lightweight, rolls up flat).
• Best for hands-free calls while driving or working → Flecom USB C Earbuds (full remote call control).
Both are wired USB-C with in-ear fit and dynamic drivers covering 20 Hz – 20,000 Hz, so the raw listening range is a wash on paper. The split comes down to packaging, noise control, and how much control you want on the cord itself. If price is the deciding factor for you, check the current price on Amazon for each — that's not something I'd guess at.
In my opinion, I'd buy the ALIANSHENG 2. The two-pack alone means I've got a backup before anything breaks, and the active noise cancellation plus the 24-month replacement warranty give it the edge for everyday commuting and noisy environments. The Flecom's reinforced cord and inline volume buttons are genuinely smart, and if I made a lot of calls on wired earbuds I'd probably flip that call. But for most people who just want reliable wired USB-C sound with a spare in the drawer, the ALIANSHENG 2 is the safer pick.
Not universally. ALIANSHENG 2 wins on the 2-pack, active noise cancellation and the 24-month warranty. Flecom wins on inline volume and call controls, a strengthened cord and metal-plated connectors. It depends on which of those you actually use.
Yes. The remote supports volume up/down, previous/next track, pause, and answer/end/reject call. The ALIANSHENG 2 spec sheet doesn't list inline volume buttons, so if that's a must-have, Flecom is the one.
On paper, ALIANSHENG 2, because it lists active noise cancellation. The Flecom set lists sound isolation, which is passive blocking from the in-ear seal. Active cancellation generally does more against steady background noise like engines or fans.
Both list broad USB-C compatibility, including recent iPhone and Galaxy models. Always confirm your exact model against the listing before buying, since USB-C audio support varies by device.
