If you want a dead-simple replacement charging cord for your Beats Studio Wireless headphones, choose Gneinour Studio Charge Cable; if you need to plug wired headphones into a modern USB-C phone or tablet and keep it charging at the same time — which is exactly what I'd want for webinars — choose DICKMITH USB C.
These two cables look similar in a product photo and solve completely different problems. One is a 3.5 mm-to-USB power cord built for a specific family of headphones. The other is a USB-C dongle that splits one port into two headphone jacks plus a fast-charging pass-through. If you're setting up a desk for long video calls, the difference matters more than the spec sheet first suggests.
• Gneinour's biggest strength: it's a direct replacement charge cord for Beats by Dre Solo and Studio Wireless headphones, with a gold-plated 3.5 mm plug, 2 A max current and built-in over-voltage, over-charging and over-heating protection.
• Gneinour's biggest trade-off: it is not an audio cable. It charges only, it tops out at 1 m/3.3 ft, and it fits devices that charge through a 3.5 mm jack — nothing else.
• DICKMITH's biggest strength: one USB-C port becomes two 3.5 mm headphone jacks plus PD charging up to 60 W (20V/3A), with a Realtek DAC chip supporting up to 24-bit/96 kHz audio.
• DICKMITH's biggest trade-off: it's a dongle, not a cable. It only works with USB-C devices, and its value depends entirely on whether your phone or tablet still has that port free.
• Pick Gneinour if you own Beats Studio or Solo Wireless headphones and lost or frayed the charging cord.
• Pick DICKMITH if you want to listen on wired headphones while your USB-C device keeps charging — the more useful choice for back-to-back webinars.
This is a single-purpose cable, and I mean that as a compliment. It exists to charge headphones that draw power through a 3.5 mm jack — specifically Beats by Dre Solo and Studio Wireless models, plus other 3.5 mm-plug-to-USB headphones, MP3 players, pocket recorders, speakers, Bluetooth headphones and the iPod shuffle. The plug is gold-plated, the internal conductor is 4-core tinned copper, and the build is PVC with a tangle-free round profile. Gneinour states it survived a 10,000-bend test, and the cable carries electronic safety certification with multiple protection systems against over-voltage, over-charging and overheating. Max current is 2 A, so it charges at a sensible rate while keeping the headphone's battery safe.
Who should buy it: anyone whose Beats Studio Wireless or Solo Wireless charging cord has gone missing, been chewed by a pet, or stopped making solid contact. At 1 m/3.3 ft and just 5 g, it lives happily in a headphone case or a laptop bag pocket without tangling into a knot. It also handles data transfer at up to 480 Mbps, which is a nice bonus for syncing a music player.
DICKMITH USB C: Who It's For
The DICKMITH adapter is the opposite kind of product: one small dongle doing three jobs. You plug it into a USB-C port and you get two 3.5 mm headphone jacks plus a USB-C charging pass-through that supports PD fast charging up to 60 W at a maximum output of 20V/3A. That means you can listen on wired headphones — or two people can listen at once — while your phone or tablet keeps topping up. For anyone who spends an afternoon in webinars, that's the whole point: no choosing between audio and battery.
Audio quality is where it earns its keep. Inside there's a Realtek DAC chip and 99% copper core wiring, with support for up to 24-bit/96 kHz output. DICKMITH also claims a signal isolation design for a stable connection and no power-supply noise, plus working in-line volume control. It's plug-and-play — no drivers, no apps. Compatibility covers iPhone 16/16 Pro/15/15 Pro Max, iPad Pro 12.9-inch (3rd–5th gen), iPad Pro 11-inch (1st–3rd gen), iPad Air 4th/5th gen, iPad Mini 6th gen, Galaxy S22/S21/S20 Ultra series, Note, Pixel and Huawei P20/P30/Mate 20 and similar USB-C phones and tablets.
Who should buy it: anyone with a USB-C device and a pair of wired headphones who wants the option of crystal clear calls in true wireless earbuds or a wired set during long meetings, and who doesn't want to think about battery percentage mid-call. It also suits travel, car audio and shared movie watching. Who should skip it: anyone with a Lightning iPhone or a micro-USB device — it's USB-C only — and anyone who wants a plain replacement charging cord rather than an adapter.
• Best for replacing a lost Beats charging cord → Gneinour Studio Charge Cable. It's built for exactly that 3.5 mm-to-USB charging job.
• Best for charging while you listen → DICKMITH USB C. PD 60W pass-through means the audio and the battery aren't competing for one port.
• Best for audio quality → DICKMITH USB C. A Realtek DAC with up to 24-bit/96 kHz output is a genuine step beyond a charge-only cord.
• Best for charging safety → Gneinour Studio Charge Cable. Certified electronics with over-voltage, over-charging and over-heating protection, capped at 2 A.
• Best for two people sharing a screen → DICKMITH USB C. Dual 3.5 mm jacks let two listeners plug in at once.
• Best for portability → Gneinour Studio Charge Cable. 5 g, 1 m, tangle-free, and it disappears into a headphone case.
• Best for a webinar desk setup → DICKMITH USB C. Wired audio plus continuous charging is exactly what an all-day call schedule needs.
• Best for a voice assistant on ear headphones setup → DICKMITH USB C, as long as your phone or tablet has the USB-C port free for the dongle.
In my opinion, the right pick comes down to one question: are you replacing a cord or upgrading a port? If you own Beats Studio or Solo Wireless headphones and need the charging cord back, I'd buy the Gneinour Studio Charge Cable — it's purpose-built, protected and cheap to keep as a spare. But if you're building a setup for webinars, I'd buy the DICKMITH USB C. Two headphone jacks, PD 60 W charging and a proper DAC chip solve a real problem: staying wired, clear and powered through a long day of calls. For that job, it's the one I'd reach for. Either way, check the current price on Amazon before you commit.
how to charge headphones faster
Use the charging method your headphones were designed for and don't exceed the cable's rated current. The Gneinour cord is rated at 2 A max with over-charging protection, and the DICKMITH adapter passes up to 60 W (20V/3A) to your phone or tablet — but the headphone's own charging circuit sets the real limit.
how to charge headphones
Match the connector to your device. Beats Studio and Solo Wireless models charge through a 3.5 mm jack, which is what the Gneinour 3.5 mm-to-USB cord is for. USB-C phones and tablets charge through their own port, and the DICKMITH adapter lets you keep using that port for audio at the same time.
is fast charging bad for headphones
Not inherently, as long as the cable and charger include protection. The Gneinour cable has built-in over-voltage, over-charging and overheating protection, and the DICKMITH adapter uses PD negotiation rather than forcing current. Fast charging becomes a risk when you use an uncertified cable that ignores the device's limits.
how to fast charge bose headphones
Bose headphones aren't listed in either data sheet, so I can't tell you a compatible cable here. Check your model's charging port first — if it's a 3.5 mm charging jack, the Gneinour cord may fit; if it's USB-C, the DICKMITH adapter is the relevant option, though neither is confirmed for Bose.
