• XERESTETK Blackshark V3 — biggest strength: a direct-fit detachable boom mic built specifically for the Razer Blackshark V3 Pro HyperSpeed, with a gold-plated 3.5mm plug.
• XERESTETK Blackshark V3 — biggest trade-off: it is a non-original replacement, so it only makes sense if you own that specific headset and your original mic is gone or failing.
• Elecan Headphone Extension Cable — biggest strength: 12 feet of slim, braided male-to-female 3.5mm cable that frees you from sitting right next to your desk or stereo.
• Elecan Headphone Extension Cable — biggest trade-off: it is a TRS cable, so it may not pass through microphone audio from TRRS headsets, and it never fixes a broken headset — it only adds length.
• Who each pick is for: XERESTETK for Blackshark V3 Pro owners doing a mic repair; Elecan for anyone whose existing headphones, speakers or car aux cable is simply too short.
This is a single-purpose part: a replacement microphone boom for the Razer Blackshark V3 Pro HyperSpeed Wireless headset. It's a wired 3.5mm detachable mic with a gold-plated connector on the end, sold as one unit in black. That's the whole product. There is no cable, no adapter, no extra hardware — just the boom you plug into the headset's mic port.
The buyer here is very specific. You own a Blackshark V3 Pro HyperSpeed, and your mic has died, gone missing, or started cutting out mid-game. Maybe the boom got snagged on something, maybe it stopped being recognized, maybe it vanished during a move. Whatever happened, the rest of the headset still works fine, so replacing the mic is far more sensible than replacing the whole thing.
The honest trade-off: XERESTETK states plainly that this is not an original Razer part — it's a third-party replacement. If you insist on OEM parts, this isn't it. And if you don't own a Blackshark V3 Pro HyperSpeed, skip it entirely; the fit is built around that one headset, and it won't rescue a different brand or model. XERESTETK also offers replacement-or-refund support if something goes wrong, which softens the risk of buying non-original. In my opinion, this is a reasonable buy for one narrow situation and a waste of money in every other one.
This is the opposite kind of product — not a repair, but a range extender. It's a 12-foot male-to-female 3.5mm aux cable, TRS stereo, with a pure copper core and 24K gold-plated connectors. The shell is zinc alloy and the exterior is tangle-resistant nylon braid. Elecan rates it for 15,000+ plug-in cycles and 10,000+ bending cycles, which tells you it's aimed at people who plug and unplug constantly.
Two design details stand out. First, the outer diameter is only 3.5mm — noticeably thinner than most aux cables — which makes it more flexible and easier to route through tight gaps, like behind a desk or through a cable hole. Second, the connector uses a stepped profile so it seats fully even with a thicker phone case on, instead of getting blocked or stuck.
The buyer profile is broad: someone whose headphones don't reach the couch, a desk worker tired of being tethered close to the tower, a car with an awkwardly placed aux port, a home stereo where the speakers sit far from the source. It works with anything that has a 3.5mm jack — phones, tablets, laptops, MP3 players, portable speakers, home theater gear, car audio.
Side-by-Side: Which Should You Choose?
• Best for replacing a dead or lost mic boom → XERESTETK Blackshark V3. It's the only one of the two that is actually a microphone.
• Best for adding 12 feet of reach to short headphones → Elecan Headphone Extension Cable. That's the entire point of the product.
• Best for a specific headset model → XERESTETK. It's built around the Razer Blackshark V3 Pro HyperSpeed and nothing else.
• Best for broad device compatibility → Elecan. Any device with a 3.5mm aux port qualifies.
• Best for durability under constant plugging → Elecan. Nylon braid, zinc alloy shell, and the stated cycle ratings are aimed at heavy daily use.
• Best for thin, flexible cable routing → Elecan. The 3.5mm outer diameter and stepped connector are designed for tight spaces and thick phone cases.
• Best for a quick repair without buying a new headset → XERESTETK. Cheaper in spirit than replacing the whole thing, assuming the rest of your headset works.
• Best if you need mic passthrough → XERESTETK, not Elecan. The TRS extension may drop microphone signal on TRRS headsets.
I'd buy the Elecan Headphone Extension Cable. Not because it's the "better" product — they're not competing for the same job — but because it solves a problem far more people actually have. Cables being too short is universal; a Blackshark V3 Pro mic breaking is niche. In my opinion, the Elecan is the smarter pick for the average shopper: 12 feet of reach, a slim braided build, and a two-year warranty. Buy the XERESTETK only if you own that exact Razer headset and your mic is genuinely dead.
No. It's designed to fit the Razer Blackshark V3 Pro HyperSpeed Wireless specifically. If you have a different headset, this replacement boom isn't the right part.
Often it won't. It's a 3-core TRS cable, and Elecan notes that TRRS headsets with a mic may not pass microphone audio through it. Check whether your headset uses a 3-core or 4-core plug.
I don't quote prices here. Both are inexpensive accessories, but the actual cost changes over time — check the current price on Amazon using the button on this page.
The Elecan. Adding length is exactly what it's built for, and 12 feet covers most desk, couch and car situations. The XERESTETK won't help you there at all.
