• lezaface Dual USB C — biggest strength: Two USB-C ports in one 3.8-inch adapter, so you can charge at 3A and listen through wired USB-C headphones at the same time, with a built-in DAC handling up to 24bit/48kHz audio.
• lezaface Dual USB C — biggest trade-off: It's an accessory, not a listening device. On its own it makes no sound — you still need your own wired USB-C headphones, and it only fits USB-C phones and tablets.
• YY KATTY Hybrid Active Headphones — biggest strength: A self-contained wireless over-ear headphone: Bluetooth 5.1, 50 hours of average battery life, and a 4-hour charge time.
• YY KATTY Hybrid Active Headphones — biggest trade-off: No headphone jack at all, so it's wireless-only, and its "hybrid active" branding sits alongside a spec sheet that lists sound isolation as the noise control.
• Who each pick is for: lezaface for USB-C phone owners who refuse to give up wired audio; YY KATTY for anyone who wants one pair of over-ear headphones for long listening sessions.
Think of the lezaface Dual USB C as a bridge. Modern USB-C phones dropped the headphone jack, and a lot of people still own wired USB-C headphones they like. This adapter plugs in, splits into two USB-C ports, and lets you do both things at once: charge on one port, listen on the other. No swapping cables back and forth, no choosing between a full battery and your music.
The spec that matters most for the "fast charge" angle is the 3A charging current. lezaface describes the setup as increasing charging speed by roughly 1.5 times, with a claimed output efficiency gain around 30% — in plain terms, the adapter is designed to pass through a serious charge rather than trickle power into your phone while you listen. For someone who games, takes calls, or streams for hours with wired headphones on, that passthrough matters. You're not stuck watching the battery drop while you're plugged in.
Audio isn't an afterthought either. There's an independent DAC chip inside handling up to 24bit/48kHz lossless output, which is the kind of spec music listeners actually notice on wired gear. There's also a microphone and volume/wire control passthrough, so calls and inline controls keep working.
Who should skip it: Anyone with a Lightning iPhone, anyone who's already gone fully wireless, and anyone expecting the adapter itself to play audio — it doesn't. It also won't help if your headphones are 3.5mm analog; this is USB-C in, USB-C out.
Build-wise it's ABS plastic with TPE strain relief that lezaface says was tested past 15,000 bend cycles at 180 degrees. It weighs 0.8 ounces and measures 3.8 inches, so it lives in a pocket without being annoying. You get two in the pack, plus a 72-month warranty and a 90-day return window — worth knowing if you want one for home and one for a bag.
YY KATTY Hybrid Active Headphones: Who It's For
The YY KATTY Hybrid Active Headphones are a completely different animal: an over-ear wireless headphone with a plastic body in blue, Bluetooth 5.1, and a 32-ohm dynamic driver covering the standard 20Hz–20,000Hz range. Deep bass and soft earpads are part of the pitch, which tells you the tuning leans warm and comfortable rather than clinical.
The headline numbers here are battery-related, and they're the reason this pair belongs in a fast-charge conversation at all. YY KATTY lists a 4-hour charge time and 50 hours of average battery life. Read those together and you get the real story: this isn't a "five minutes for three hours" style headphone. It's a headphone you charge for a few hours and then forget about for the better part of a week. For most people, that's the more useful kind of fast charging — the kind you don't have to think about.
There's no headphone jack. Zero wired option. Everything runs over Bluetooth 5.1, with a built-in mic for calls. The noise control field says sound isolation, so treat these as passive-isolating over-ears rather than a full active noise-cancelling flagship — the "hybrid active" wording in the product name shouldn't be read as a promise of airline-cabin silence.
Who should buy it: Teens and adults who want one pair of over-ear headphones for commuting, studying, gaming, or long work sessions, and who value not charging something every night. The blue finish and soft earpads suit casual, all-day wear.
Who should skip it: Anyone who needs a wired connection for zero-latency monitoring, anyone who wants a genuine ANC experience, and anyone whose devices rely on a 3.5mm or USB-C audio jack.
Side-by-Side: Which Should You Choose?
• Best for battery life → YY KATTY Hybrid Active Headphones. 50 hours of average life is the number that stands out on either sheet.
• Best for charging speed on the go → lezaface Dual USB C. The 3A current rating is the most aggressive charging figure between the two.
• Best for audio quality on paper → lezaface Dual USB C. A dedicated DAC with 24bit/48kHz output is a more concrete audio spec than a 32-ohm dynamic driver with a standard frequency range.
• Best for a complete listening setup out of the box → YY KATTY Hybrid Active Headphones. It makes sound. The adapter doesn't.
• Best for travel and portability → lezaface Dual USB C. 0.8 ounces and under 4 inches. It disappears into a pocket.
• Best for long, untethered sessions → YY KATTY Hybrid Active Headphones. No cable, no jack, no tether to your phone.
• Best for phone calls with your own wired headset → lezaface Dual USB C. Mic, call, and volume control passthrough are all supported.
In my opinion, the right buy depends entirely on what's missing from your setup. If your problem is "my USB-C phone has no headphone jack and I hate choosing between charging and listening," I'd buy the lezaface Dual USB C — the dual-port design, the 3A passthrough, and the built-in DAC solve that specific headache cleanly, and you get two in the pack. If your problem is "I want one pair of over-ear headphones I charge a couple of times a week at most," I'd buy the YY KATTY Hybrid Active Headphones, because 50 hours of average playtime is hard to argue with. They're not competitors. They're answers to two different questions — and if you own a USB-C phone and no wireless headphones yet, honestly, you might want both.
how to charge headphones faster
The two levers are the charger you plug into and the headphone's own charge-time rating. The YY KATTY Hybrid Active Headphones list a 4-hour charge time, so the fastest realistic path is a charger that comfortably exceeds what the headphone draws and a cable rated for the current. The lezaface adapter, meanwhile, is rated at 3A of passthrough current, which is about as much as a phone adapter of this type is built to handle.
how to charge headphones
For the YY KATTY pair, you charge over its charging connection and it fills in roughly 4 hours for about 50 hours of average use — meaning you're charging perhaps once or twice a week in normal use, not nightly. For wired USB-C headphones on a modern phone, the lezaface Dual USB C lets you plug the charger into one port and your headphones into the other, so charging happens while you listen instead of after.

The principle transfers: use a charger and cable that meet or exceed the headphone's rated input, and avoid daisy-chaining through weak USB hubs, which throttles current. One useful trick from the lezaface adapter's design is separating power from audio — if a single port is doing both jobs, splitting them lets the charger deliver full current instead of sharing it. If you're unsure what your specific headphones accept, check the manufacturer's stated charge time and input rating before assuming a bigger charger helps.
is fast charging bad for headphones
Not inherently. Charge time is a design spec, and the YY KATTY Hybrid Active Headphones are built around a 4-hour charge with a 50-hour average runtime, which is a normal, healthy ratio rather than an aggressive one. The lezaface adapter's 3A passthrough is a current rating for the phone side, and it's designed to deliver that while audio passes through a separate port. In my opinion, the bigger practical risk with any of this gear is cheap cables and worn connectors, not the charging speed itself. Just check the current price on Amazon before you commit, since both of these are inexpensive accessory-class purchases where the numbers move around.
