If you want a compact two-pack adapter with an explicit wired-control and mic passthrough feature set and a clearly stated DAC sampling spec, choose JXMOX USB Type C; if you need a five-pack of simple listen-and-talk adapters to scatter across bags, desks and cars, choose basecolors 5.
• JXMOX USB Type C — biggest strength: A 2-pack of USB-C-to-3.5mm dongles built around a smart DAC chip rated for 16Bit/48Khz decoding, with in-line wire control (mic, volume, pause/play) called out as a supported function.
• JXMOX USB Type C — biggest trade-off: You get two adapters, not five, so if you lose cables often you'll be re-buying sooner. Its compatibility list is long but still a list — some newer or niche USB-C devices aren't named.
• basecolors 5 — biggest strength: Five adapters in one package, each using a low-power DAC chip that converts digital to analog at 48,000 samples per second, all in the same ABS-and-nylon-braided build rated for 20,000+ bends.
• basecolors 5 — biggest trade-off: The listing openly states that microphone functionality and volume adjustment on 3.5mm iPhone headsets are not supported, and only TRRS/TRS-style plugs are — TS and mic-only plugs won't work.
• Who JXMOX is for: Someone who wants one adapter for the phone and one as a spare, and who cares about in-line controls and a stated bit-depth/sample-rate figure.
• Who basecolors 5 is for: Someone who wants a small fleet of cheap, no-fuss adapters to leave in a glovebox, laptop bag, desk drawer and backpack without thinking about it.
The JXMOX adapter is a USB-C male to 3.5mm female dongle, and it's sold as a two-pack. What stands out in its spec sheet is the feature list on the audio side. JXMOX calls out a smart DAC chip with low power consumption and "excellent and stable decoding performance," and it explicitly states a maximum supported sampling rate of 16Bit/48Khz. That's a concrete number, and for anyone who has been burned by a dongle that just quietly sounds worse than the phone's built-in jack, a stated decoding spec is a useful signal — it tells you the manufacturer at least thought about the conversion stage rather than treating it as an afterthought.
The second thing worth noting is the wire control support. JXMOX describes the adapter as supporting music playback, phone calls, and in-line controls like microphone volume, pause and play — and it mentions gaming as a use case. That matters because a lot of cheap dongles will pass audio out but drop the mic line entirely, turning your headset into headphones. If you take calls with wired earbuds that have a mic and a button, that listed function is the feature to care about.
Buy it if: you want a spare in the box, you use a wired headset with a mic and in-line controls, or you specifically want a stated 16Bit/48Khz DAC spec on paper. Skip it if: you're the type who loses dongles constantly and would rather have five mediocre ones than two good ones, or if you need a device that isn't in the compatibility list.
basecolors 5: Who It's For
The basecolors adapter does the same core job — USB-C male to 3.5mm female — but the pitch is volume: five adapters in one package, all white, all with the same ABS-and-nylon anti-winding build. The DAC here is described as an "intelligent low-power chip" that converts digital to analog while maintaining the original sound quality, with a figure of 48,000 samples per second. Note that 48,000 samples per second is the same 48kHz ceiling JXMOX states, just expressed as a sample count rather than as "16Bit/48Khz." Functionally, both adapters are claiming the same 48kHz class of conversion. Don't let the different phrasing fool you into thinking one is in a higher tier.
Durability language is almost identical: high-quality ABS plus nylon anti-winding wire, 20,000+ bends, shielded enamel wire for stable signal transmission in daily use. If you read both sheets side by side, the construction story is the same story. That's not a knock — it just means build quality isn't the deciding factor between these two.
The deciding factor is the disclaimer, and basecolors deserves credit for being blunt about it. The listing states plainly that microphone functionality and volume adjustment on 3.5mm iPhone headsets are not supported, and that the adapter supports listening and speaking but only with TRRS and TRS plugs — TS and mic-only devices won't work. Read that carefully: "supports listening and speaking" means a standard TRRS headset with a mic should work for calls, but Apple's own 3.5mm EarPods-style volume buttons won't do anything. If you were planning to use the inline volume rocker on wired Apple earphones, that's the thing to know before you buy.
Buy it if: you want five adapters so there's always one within arm's reach — car, backpack, desk, partner's bag, spare — and you don't care about inline volume buttons on Apple-style headsets. Skip it if: in-line volume control on a 3.5mm headset is a must-have, or you own TS/mic-only gear.
• Best for in-line controls and mic buttons → JXMOX USB Type C. It explicitly lists wire control including volume, pause and play.
• Best for having a spare everywhere → basecolors 5. Five units versus two means you stop hunting for a dongle.
• Best stated decoding spec on paper → tie. JXMOX says 16Bit/48Khz; basecolors says 48,000 samples per second. Same 48kHz neighborhood.
• Best for Apple headset volume buttons → JXMOX USB Type C, because basecolors states outright that iPhone 3.5mm volume adjustment isn't supported.
• Best for the widest named compatibility list → JXMOX USB Type C, whose list runs through iPhone 17/16/15 series, Galaxy S25 down to S8, Note 8–20 Ultra, iPad Pro, iPad mini 6, iPad Air 4, MacBook, Pixel, OnePlus and Huawei.
• Best for Huawei and newer Pixel owners → basecolors 5, which names Huawei Mate 60/50/40/30/20/10 and P60–P20, plus Pixel 9/8/7/6.
• Best for travelling light → JXMOX USB Type C. 11cm and about 9g, with one spare rather than a pile.
• Best for households with multiple USB-C phones → basecolors 5. Five adapters cover several people at once.
I'd buy the JXMOX USB Type C. In my opinion, the two features that actually change day-to-day use are the mic/wire-control support and the explicit 16Bit/48Khz DAC figure, and JXMOX states both more clearly. The 2-pack also covers the realistic scenario — one on the phone, one in the bag — without leaving you with three adapters you'll never touch.
If your priority is sheer quantity and you mostly just want audio out with occasional calls, basecolors 5 is the more sensible buy, and it's refreshingly honest about its limitations. But for a wired headset with a mic and a button, I'd go JXMOX.
FAQ
No. The listing says microphone functionality and volume adjustment on 3.5mm iPhone headsets are not supported. It supports listening and speaking with TRRS and TRS plugs, but TS and mic-only devices won't work.
JXMOX USB Type C ships as a 2-pack. basecolors 5 ships as a 5-pack. Both are single-port USB-C to 3.5mm female adapters with no plug or external power required.
Both name Galaxy S-series and Pixel models in their compatibility lists, so either works. If you specifically own a Huawei Mate 60/50/40/30/20/10 or P60–P20, or a Pixel 9/8/7/6, basecolors names those explicitly. If you want in-line controls, go JXMOX. For either one, check the current price on Amazon before you commit.
