• Haourlife Replacement Magnetic Charging — biggest strength: a dedicated magnetic charging cord built specifically for the 4-pin, 7.62mm-pitch interface used by many bone conduction headphones, smartbands and smartwatches. Biggest trade-off: it only fits that one interface — it won't help you listen to anything or charge a USB-C phone.
• tiavalmax USB-C Headphone Adapter — biggest strength: it splits one USB-C port into a USB-C headphone jack plus a PD 60W charging port, so audio and fast charging happen at once. Biggest trade-off: it needs a USB-C (not Lightning) device, and it's an audio/charging dongle, not a replacement cable for a wearable.
• Pick Haourlife if your problem is a missing charging cord for a magnetic-interface headphone, band or watch.
• Pick tiavalmax if your problem is a phone or tablet with no headphone jack that you want to keep charging while you listen.
This is a single-purpose part, and that's the point. The Haourlife Replacement Magnetic Charging is a 60cm (24-inch) USB charging cord with a 4-pin magnetic connector at a 7.62mm pitch. It's made for the kind of wearable that snaps onto a small magnetic pad to charge — bone conduction headphones, smartbands and smartwatches that use that interface.
The connector is male-to-male with four pins, the wire core is copper, and the cable is round and black. Haourlife lists it as supporting data transmission as well as charging. If you've lost the original cable for your headphone or band, or the one you have has frayed at the connector, this is the exact kind of replacement you'd look for. The magnetic tip means you don't have to hunt for a tiny port in the dark — it just snaps into place.
Who should buy it: anyone whose device uses a 4-pin magnetic interface at 7.62mm pitch and who needs a replacement or a spare. The 60cm length is handy for a bedside table, a desk or a car, and because it's a simple cord, it's easy to keep one at home and one in a bag.
tiavalmax USB-C Headphone Adapter: Who It's For
The tiavalmax USB-C Headphone Adapter solves a very modern annoyance: phones and tablets dropped the headphone jack, but you still want to plug in wired headphones — and you don't want to stop charging to do it. This 2-in-1 dongle takes your USB-C port and splits it into a USB-C headphone jack and a USB-C PD charging port.
On the audio side, it uses a built-in digital-to-analog converter with up to 24-bit/96kHz sampling, and tiavalmax claims stable decoding with low power draw and no static or interruption. It's plug-and-play — no software or drivers. It supports music, calls, volume control, microphone and remote, and data transfer. On the charging side, it supports up to 60W PD. The company suggests a PD wall charger for the fastest speeds and notes it may not support Quick Charge on some phones. The strain relief is rated to 15,000+ bending cycles, which matters for something that lives in a pocket or bag.
Compatibility is broad but specific: USB-C iPhones (17, 16 and 15 series), USB-C iPads, MacBook, Samsung Galaxy/Note/Tab, Google Pixel, LG, Sony, Moto and more, plus headphones, earphones, speakers, car stereos, home stereos and mics. It's described as MFi certified for clean USB-C connectivity on iOS 17 or later and Android without error messages.
Who should buy it: anyone with a USB-C phone or tablet who wants to use wired USB-C headphones or an aux cable while charging — gamers, call-heavy users, commuters, and people whose wired headphones simply sound better to them than their wireless pair. Who should skip it: anyone on a Lightning-port device (it won't work), and anyone expecting it to act as a replacement charging cable for a wearable — that's a completely different job.
• Best for replacing a wearable charging cable → Haourlife Replacement Magnetic Charging. It's built for the 4-pin, 7.62mm magnetic interface.
• Best for listening and charging at the same time → tiavalmax USB-C Headphone Adapter. Audio and 60W PD charging from one port.
• Best for fast charging while you use your phone → tiavalmax. PD 60W pass-through is its headline feature; pair it with a PD charger.
• Best for bone conduction headphones, smartbands or smartwatches → Haourlife. That's the device class it's designed around.
• Best for wired USB-C headphones, aux cables, car stereos and mics → tiavalmax. It handles audio playback, calls, mic and remote.
• Best for cable length on a desk or nightstand → Haourlife. A fixed 60cm cord, no dongle to lose.
• Best for audio quality on paper → tiavalmax. Up to 24-bit/96kHz decoding via its built-in DAC.
• Best for durability in a pocket → tiavalmax. Strain relief rated to 15,000+ bending cycles.
• Skip Haourlife if your device isn't 4-pin/7.62mm, or if it's Bose Alto smart glasses or similar eyewear.
• Skip tiavalmax if you're on a Lightning port or you want a replacement cable, not an adapter.
These two don't really compete — they fix different problems, so the honest answer is that the right pick depends on which problem is yours. If a wearable's charging cord went missing or wore out, I'd buy the Haourlife Replacement Magnetic Charging, but only after confirming my device's connector matches the 4-pin, 7.62mm spec. If I wanted to keep charging my USB-C phone while listening through wired headphones, I'd buy the tiavalmax USB-C Headphone Adapter — its 60W PD pass-through and 24-bit/96kHz DAC make it the more capable everyday tool. In my opinion, most people searching for "fast charge headphones" actually want the tiavalmax, because it's the one that charges and plays at the same time.
FAQ
how to fast charge bose headphones
Bose doesn't appear in either data sheet, so I can't speak to Bose specifically. The Haourlife cable is listed as not compatible with Bose Alto smart glasses, and the tiavalmax adapter is a USB-C audio/charging dongle rather than a headphone charging cable. For your own headphones, use the charger and cable the manufacturer specifies.
Charging speed depends mostly on the charger and the device, not the cable alone. The tiavalmax adapter supports up to 60W PD pass-through and tiavalmax suggests using a PD wall charger for faster speeds, noting it may not support Quick Charge on some phones. The Haourlife cable is a plain charging/data cord with a copper core — it doesn't advertise any fast-charge standard.
how to charge headphones
For magnetic-interface headphones, bands and watches, you snap the Haourlife cable's 4-pin magnetic tip onto the device and plug the USB end into a power source. For wired listening on a USB-C phone, the tiavalmax adapter lets you plug in headphones and a charger at the same time, so you can listen while the device tops up.
is fast charging bad for headphones
Neither data sheet makes any claim about fast charging harming headphones. The tiavalmax adapter is designed to pass up to 60W PD to a phone, tablet or laptop while audio plays, which is normal USB-C Power Delivery behavior. For headphone battery health, follow the charging guidance that came with your specific model.
