How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a simple, durable replacement charging cord for 3.5mm-to-USB headphones like Beats Studio Wireless, choose Gneinour Studio Charge Cable; if you need to charge your iPhone while two people listen through wired 3.5mm headphones at the same time, choose INVERSE NET 3.
• Gneinour Studio Charge Cable — biggest strength: a purpose-built 1m USB-to-3.5mm male-to-male charging cord with gold-plated connectors, 2A max current and a tangle-free, bend-tested PVC build.
• Gneinour Studio Charge Cable — biggest trade-off: it is a charging/data cable, not an audio cable, and it only fits devices whose charging port is a 3.5mm jack.
• INVERSE NET 3 — biggest strength: a 3-in-1 Lightning adapter with dual 3.5mm jacks so two people can listen while the phone charges, plus a built-in DAC chip and 2.4A fast charging.
• INVERSE NET 3 — biggest trade-off: it is Apple-only (Lightning), and it is an adapter, not a replacement cord for a headphone's own charging port.
• Who each is for: Gneinour for owners of Beats Studio Wireless / Solo Wireless and other 3.5mm-plug-to-USB headphones who just need a reliable charging cord. INVERSE NET 3 for iPhone and iPad users who want to share audio with a second pair of wired headphones while topping up the battery.
The Gneinour Studio Charge Cable is a single-purpose product, and that is exactly its appeal. It is a 1m (3.3ft) male-to-male cord: USB Type-A on one end, 3.5mm on the other. It exists because a handful of popular headphones — most notably the Beats by Dre Studio Wireless and Solo Wireless lines — charge through a 3.5mm jack instead of USB-C or micro-USB. If your headphones died and you lost the original cord, this is the kind of replacement you are hunting for. Note the wording in the listing itself: it is a charging cable, not an audio cable. That distinction matters, because a 3.5mm plug looks identical whether it carries power or sound.
Who should buy it: anyone with Beats Studio Wireless or Solo Wireless headphones, or another device that charges through a DC 3.5mm port — MP3 players, pocket recorders, Bluetooth headphones, speakers, even an iPod shuffle. Who should skip it: anyone whose headphones charge over Lightning, USB-C or micro-USB, and anyone hoping to use it as an audio cable. It will not do that, and the listing is refreshingly upfront about it.
INVERSE NET 3: Who It's For
The INVERSE NET 3 solves a completely different problem: the missing headphone jack on modern iPhones. It is a 3-in-1 Lightning adapter — one Lightning plug into your phone, and on the other side, two 3.5mm jacks plus a Lightning charging port. So you can plug in two pairs of wired headphones and charge at the same time. For a long flight, a road trip, or two kids sharing a movie on one iPad, that dual-jack layout is the entire point.
The spec sheet is more interesting than the average dongle. Inside is a DAC smart chip supporting 96 kHz / 24-bit audio output, which is the part that actually converts digital audio to something your wired headphones can play. The adapter uses a 100% copper core and is rated for 2.4A fast charging, which INVERSE NET describes as roughly 1.5x faster charging than a standard adapter. It is plug-and-play with no drivers, and at roughly 6.7 x 2.8 x 0.8 inches and 20g it slips into a backpack or handbag without a second thought. Compatibility covers iPhone 14/13/12/11 series down through XS, XR, X, 8, 7, 6 and iPad, on iOS 9.2 and above, with a decoder chip so system updates don't break it. INVERSE NET also lists a lifetime warranty type with a 2-year warranty description — worth registering if you buy.
Who should buy it: iPhone or iPad owners who still own wired 3.5mm headphones, especially households where two people want to listen together, or anyone who wants to charge and listen simultaneously without a separate splitter. Who should skip it: Android users, anyone on USB-C, and anyone looking for a replacement charging cord for a pair of headphones. It does not do that job at all.
• Best for reviving Beats Studio Wireless headphones → Gneinour Studio Charge Cable. It is built specifically for 3.5mm-to-USB charging, so it is a direct replacement rather than a workaround.
• Best for sharing audio with a second person → INVERSE NET 3. Two 3.5mm jacks working simultaneously is a feature the Gneinour cable simply does not have.
• Best for charging and listening at the same time on iPhone → INVERSE NET 3. The dedicated Lightning charging port handles both at once.
• Best for cable durability and everyday abuse → Gneinour Studio Charge Cable. The tinned copper core, gold plating and 10,000-bend PVC claim are aimed at daily wear.
• Best for audio quality on wired headphones → INVERSE NET 3. The DAC chip's 96 kHz / 24-bit output is a genuine audio spec; the Gneinour cable carries no audio at all.
• Best for travel-friendly simplicity → Gneinour Studio Charge Cable. One 1m cord, 5g, tangle-free — nothing to configure.
• Best for iPhone/iPad families and friends → INVERSE NET 3. Its stated purpose is letting two people enjoy a movie or music on one device.
• Best for non-Apple devices → Gneinour Studio Charge Cable. INVERSE NET 3 is Lightning-only; Gneinour's cable works with any device that charges over a 3.5mm jack.
In my opinion, these two products should not really be compared as substitutes, because they do different jobs — so the honest answer is to buy the one that matches your device. If you own Beats Studio Wireless or Solo Wireless headphones and need a replacement charging cord, I would buy the Gneinour Studio Charge Cable: it is purpose-built, rated for 2A, gold-plated, and the listing is clear about what it does and does not do. If you own an iPhone or iPad and want to charge while two people listen on wired headphones, I would buy the INVERSE NET 3 instead. The deciding factor is your port, not your preference.
No. The listing explicitly states it is a 3.5mm jack connector cable for charging, not an audio cable. It moves power and data up to 480 Mbps, so do not expect sound to pass through it.
No. It uses a Lightning connector and is listed as compatible with iPhone and iPad models only, from iPhone 6/7/8 through the iPhone 14 series, on iOS 9.2 and above.
Yes. That is its core function — one Lightning charging port plus two 3.5mm jacks working simultaneously, with 2.4A fast charging.
I do not quote prices here. Both are low-cost accessories, and which is better value depends entirely on your device — a cheap cable you cannot use is worse than a slightly pricier adapter you use daily. Check the current price on Amazon before deciding.
