How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a proven, no-fuss 2-in-1 adapter for listening and charging at once, choose LERTOSEN USB C; if you need three ports, a studio-grade DAC and a USB-C headphone jack on top of the classic 3.5mm one, choose Criello USB-C. Both do the same core job — they let you plug wired headphones into a USB-C phone while the charger stays connected — but they split the job in different ways, and the right pick comes down to how many things you want to plug in at the same time.
• LERTOSEN USB C — biggest strength: a smart DAC aimed at HiFi audio, PD 60W charging and a metallic grey finish, in a tiny 2-in-1 dongle that covers a very long list of phones, tablets and laptops.
• LERTOSEN USB C — biggest trade-off: it is strictly a two-port device (3.5mm audio plus USB-C power), and it is explicit about what it won't do — no QC 3.0, no Samsung Super Fast Charging, no OMTP headsets, and no wire control or calling on iPad Pro 2018 or on phones that already have a 3.5mm jack.
• Criello USB-C — biggest strength: a genuine 3-in-1 splitter — one USB-C port for PD charging, one USB-C headphone jack and one 3.5mm jack — with an advanced DAC running 24bit/48kHz, metal-coated connectors and a strain-relief cable rated for 20000+ bends.
• Criello USB-C — biggest trade-off: the USB-C headphone jack and the 3.5mm jack cannot be used at the same time, you can't push a charging cable into the headphone jack, and it tops out at 60W nominal power like the LERTOSEN.
• Who each is for: LERTOSEN USB C suits the buyer who wants the simplest possible listen-and-charge dongle with the broadest device list and a metal body; Criello USB-C suits the buyer who wants a third port, a higher-resolution DAC spec and a cable built for heavy daily flexing.
The LERTOSEN USB C is a 2-in-1 adapter: a 3.5mm aux jack on one side, a USB-C PD port on the other, so you can keep a charger plugged in while your wired headphones play. Its headline feature is a smart DAC tuned for HiFi audio, which is the part that actually matters — a good DAC is what keeps your wired headphones sounding like wired headphones instead of thin and noisy. Around that sit the practical bits: PD 60W fast charging, a robust build in a metallic grey finish, and a control-and-calling feature set for the models that support it.
Who should skip it? Anyone who needs three ports. If you want to charge, use a 3.5mm headset and also use a USB-C headset — or you simply want a spare USB-C audio path — this adapter doesn't offer that. It also flags real limits: no QC 3.0, no Samsung Super Fast Charging, no OMTP headsets, no separate microphone accessories, and no wire control or calling on iPad Pro 2018 or on a phone that already has a 3.5mm jack, where the calling function simply will not work. If any of those apply to your setup, read the Criello section before you commit.
Criello USB-C: Who It's For
The Criello USB-C takes the same idea and adds a port. It splits a single USB-C slot into three: a USB-C port that supports PD fast charging, a USB-C headphone jack, and a 3.5mm audio jack. That means you can charge quickly while listening to music, gaming, taking calls, driving or watching video, and the adapter supports volume adjustment while the charger is connected. For anyone whose phone has no headphone jack and only one USB-C port, that third socket is the whole point — it turns one port into a small hub.
The audio side is specified rather than vague. Criello lists an advanced DAC with 24bit/48kHz resolution and active noise cancellation, pitched at studio-grade sound with clean detail and no distortion. Whether your ears catch the difference depends on your headphones and your source, but a higher-resolution DAC spec is a real, checkable difference on paper against a plain "HiFi" claim. The build follows suit: metal-coated connectors for better contact and lossless transmission, a relief strain design rated for 20000+ bending tests, aircraft-grade aluminum connectors, an abrasion-resistant TPE cable, and a plug-and-play setup with no drivers. It measures 5.22 x 1.2 x 0.15 inches, so it disappears in a pocket.
The trade-offs are stated plainly. The USB-C headphone jack and the 3.5mm jack cannot be used at the same time, so the third port is a choice, not a bonus channel. Don't insert the charging cable into the headphone jack — it won't work. Power is 60W nominal at 3A and 20V input, so it's in the same fast-charging territory as the LERTOSEN rather than above it. Compatibility leans toward iPhone 15/16/17 Pro, Plus and Pro Max, Galaxy S23 down to S21, Note 20 and 10 series, iPad mini 6, iPad Pro 2022/2021/2020, iPad Air 6/5/4, iPad 2022, MacBook Pro and Air, Huawei Mate 40 down to P20, and Pixel 8/7. If your device is older than that, check the list carefully — the LERTOSEN sheet reaches further back into the Pixel and Galaxy lines.
Side-by-Side: Which Should You Choose?
• Best for a third port → Criello USB-C. It gives you USB-C charging, a USB-C headphone jack and a 3.5mm jack. LERTOSEN USB C gives you two ports, full stop.
• Best for a single, simple dongle → LERTOSEN USB C. One audio jack, one charging port, no decisions to make.
• Best build against everyday abuse → Criello USB-C. The 20000+ bending rating, strain relief, TPE cable and metal-coated connectors are specific durability claims. LERTOSEN counters with a robust design and a metallic grey finish, which is more about feel than a stated test figure.
• Best for the widest device list, including older phones → LERTOSEN USB C. Its sheet reaches Pixel 6/5/4/3/2 XL, older Galaxy S and Note models, and Huawei Mate 30/20/10 Pro and P30/P20.
• Best for iPhone 17 and current Samsung flagships → either. Both sheets list the iPhone 17 family and the S25/S24/S23 or S23/S22/S21 range, so this is a tie.
• Best for laptop and tablet use → Criello USB-C on ports, LERTOSEN USB C on breadth. Both cover MacBook and iPad, but only Criello gives you a USB-C audio socket as well.
• Best for people who hate fine print → LERTOSEN USB C, but only if you've read it. Its exclusions (no QC 3.0, no Super Fast Charging, no OMTP) matter. Criello's fine print is shorter but sharper: don't mix the two headphone jacks.
In my opinion, Criello USB-C is the better buy for most people shopping in 2026, and it's the one I'd pick. Three ports beat two, the 24bit/48kHz DAC and active noise cancellation are a more concrete audio claim than a general HiFi label, and the 20000+ bending rating plus strain relief suggests it will survive being shoved in and out of a bag every day. I'd only steer you to LERTOSEN USB C if your device is older or more unusual — an older Pixel, a Mate 20 or P20, a specific Galaxy Note — where its compatibility list goes deeper, or if you genuinely want nothing more than a two-port listen-and-charge dongle. Check the current price on Amazon for both before deciding, since that gap can shift which one feels like the smarter pick.
I don't quote prices here, because they change often and neither data sheet includes them. Use the price button on this page to check the current price on Amazon for both, then compare against the features you actually need — the third port on the Criello is the main thing you're paying for.
No. Criello states clearly that USB-C headphones cannot be used simultaneously with 3.5mm headphones, so the third port is an alternative, not an extra channel. LERTOSEN USB C only has one audio output anyway, so neither adapter lets you run two headsets together.
It supports PD 60W charging but explicitly does not support QC 3.0 or Samsung Super Fast Charging, so a Samsung will charge, just not at the fastest rate that phone can accept. Criello's sheet lists 60W nominal power at 3A and 20V input, which is comparable rather than higher.
On paper, Criello USB-C makes the stronger durability case: a relief strain design rated for 20000+ bending tests, aircraft-grade aluminum connectors, an abrasion-resistant TPE cable and metal-coated connectors for stable contact. LERTOSEN USB C is described as robust and durable with a metallic finish, but doesn't quote a bending figure, so if you're hard on cables, Criello's spec sheet is the more reassuring one.
