If you want to keep a wired 3.5mm headset alive while your USB-C phone fast-charges at up to 60W, choose Togconn USB C; if you need all-day wireless sound with an 80-hour battery and fast charging of its own, choose GREYOLK Open Ear. These two look like they belong in the same search, but they solve completely different problems. One is a tiny adapter that splits a single USB-C port into audio plus power. The other is a pair of open-ear Bluetooth earbuds built for running and workouts. Here's how to tell which one actually fits your pocket.
• Togconn USB C — biggest strength: one USB-C male plug gives you a 3.5mm audio jack and a PD 60W charging port at the same time, so you never choose between listening and topping up.
• Togconn USB C — biggest trade-off: it's an adapter, not a listening device. Without a wired headset or your phone's charger, it does nothing on its own.
• GREYOLK Open Ear — biggest strength: an 80-hour battery average life, Bluetooth 5.4, and an open-ear hook design that keeps you aware of traffic and conversations.
• GREYOLK Open Ear — biggest trade-off: it's wireless only, with no 3.5mm jack, so it can't help you use a wired headset or pass through a charge to your phone.
• Who each pick is for: Togconn USB C for anyone with a USB-C phone or tablet and a favorite wired headset; GREYOLK Open Ear for runners, cyclists and gym-goers who want nothing in their ear canal.
Think of Togconn USB C as a problem-solver for one very specific frustration: modern phones dropped the headphone jack, and the single USB-C port is already busy. This adapter plugs into that port and splits it into two — a 3.5mm AUX female jack for your wired headphones, and a Type C PD port rated up to 60W (20V, 3A). Plug and play, no driver required. In my opinion that dual role is the whole reason to buy it: you can listen to music and charge at the same time instead of unplugging one to do the other.
The build is aimed at daily pocket life. The jacket is nylon braided and the listing states it passed 10,000+ bending tests, while the port housings use an aluminum shell for wear resistance and heat dissipation. It's light — 0.01 kg — and small enough to leave on a keyring or in a bag pocket. Togconn also backs it with a 24-month warranty and says questions are resolved within 24 hours.
Who should buy it? Anyone with a USB-C device — the compatibility list covers iPhone 15, 15 Plus, 15 Pro and 15 Pro Max, Galaxy S20 through S22 Ultra, Note 20, Galaxy Z Fold 3 and 4, iPad Pro, and Pixel 4/3. If you own a wired headset you love and refuse to replace it with wireless buds, this is the cheap fix. Who should skip it? If you've fully moved to Bluetooth, or you want earbuds rather than an adapter, this isn't a listening product at all. And if your phone still has a headphone jack, you don't need it.
GREYOLK Open Ear is the opposite philosophy: nothing goes inside your ear, and nothing is wired. The earpieces rest outside the ear canal on an ergonomic hook, which the brand describes as pressure-free comfort for all-day wear. The real benefit is awareness — you hear traffic, conversations and ambient noise while your playlist keeps playing. That's exactly what makes open-ear a smart pick for running, cycling and outdoor training, where shutting out the world is a safety problem, not a feature.
The wireless side is current: Bluetooth 5.4 with one-step pairing and a stable link that switches between phone, tablet and laptop, with low latency even in crowded signal environments. Controls are touch-based, so you can handle music, calls, volume and voice assistants with taps instead of reaching for your phone. The build is IPX5 waterproof and sweat-resistant, which covers intense gym sessions and unexpected rain. Battery average life is listed at 80 hours, and the product supports fast charging. A charging station is included, and the warranty runs 1 year.
Who should buy it? Runners, cyclists, gym regulars, and anyone who finds in-ear buds uncomfortable or unhygienic over long sessions. It's also a good fit if you take calls on the move — ENC noise cancelling targets voice pickup on calls. Who should skip it? If you want maximum isolation on a noisy train, open-ear design is working against you by intention. And if you need to keep using a wired 3.5mm headset, there's no jack here at all.
• Best for charging speed on a phone → Togconn USB C. It passes up to 60W (20V, 3A) through its PD port while audio plays.
• Best for battery life → GREYOLK Open Ear. 80 hours average life per the spec sheet, with fast charging to top it up.
• Best for using a wired headset → Togconn USB C. A dedicated 3.5mm AUX jack is the entire point.
• Best for running and workouts → GREYOLK Open Ear. Open-ear hooks, IPX5 sweat and water resistance, touch controls.
• Best for staying aware of your surroundings → GREYOLK Open Ear. The open design never seals your ear canal.
• Best for travel with one USB-C port → Togconn USB C. Audio and charging at once means one port does two jobs.
• Best for call clarity on the move → GREYOLK Open Ear. ENC noise cancelling is aimed at voice pickup.
• Best for a phone that still has a headphone jack → neither. You already have the audio output you need.
In my opinion, the honest answer is that these aren't competitors — they're two answers to two different questions. If your problem is "my USB-C phone can't charge and play wired audio at the same time," buy Togconn USB C. It's a focused, well-built adapter with a 60W PD port, a 3.5mm jack, braided construction and a 24-month warranty. If your problem is "I want wireless sound for running without blocking out the world," buy GREYOLK Open Ear. If I had to pick one for the average shopper searching "fast charge headphones," I'd lean GREYOLK Open Ear, because it's an actual listening device with 80-hour battery life and fast charging built in.

FAQ
how to charge headphones faster
how to charge headphones
For GREYOLK Open Ear, place the earbuds in the included charging station and connect it to a power source. The 80-hour average battery life means you're charging far less often than with typical buds. For wired setups, the Togconn adapter charges the phone while your 3.5mm headphones stay plugged in — your headphones draw no power from it.
is fast charging bad for headphones
Fast charging is a normal feature, and GREYOLK Open Ear lists it directly, so the design accounts for it. Heat is the usual concern with any battery, which is why the Togconn adapter uses an aluminum shell for heat dissipation on the charging side. Follow the manufacturer's charging instructions and you're fine.
how to fast charge bose headphones
This page covers Togconn USB C and GREYOLK Open Ear, so I can't speak to Bose models. The general rule holds: use the cable and power source the brand specifies. If your goal is charging a phone while listening on wired headphones, Togconn's 60W PD port is the relevant part here.
