How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a self-contained wireless listening experience with adaptive noise cancellation and AI features, choose Samsung Galaxy Buds 4; if you need a long, low-resistance cable to physically extend a wired headphone or in-ear monitor run, choose 64 Audio Hi-Res Headphone Extension.
• Samsung Galaxy Buds 4 — biggest strength: A complete wireless earbud system: Hi-Res Audio, Adaptive Active Noise Cancellation, a new stay-put fit, IP54 splash/dust resistance and AI features like Live Translate.
• Samsung Galaxy Buds 4 — biggest trade-off: It's a closed wireless ecosystem with a 6-hour average battery life per charge and a 5-minute charge time, and it only delivers its smartest tricks when paired with a Galaxy S26 Series phone.
• 64 Audio Hi-Res Headphone Extension — biggest strength: A 10ft professional-grade extension with Neutrik and Rean connectors, 44 pure copper wires (22 AWG) across 3 cores, and an ultra-low 0.4 Ohm resistance for clean signal transmission.
• 64 Audio Hi-Res Headphone Extension — biggest trade-off: It makes no sound on its own. It's a passive cable, so you need the headphones, IEMs or mixer you're extending — and it's meant for indoor use.
• Who each pick is for: Pick the Buds 4 for everyday wireless listening, calls and travel; pick the 64 Audio extension for studio, live-performance or gaming setups where you need more reach without degrading the signal.
The Galaxy Buds 4 is a true wireless earbud built around convenience and smart features. It uses a dynamic driver and supports Hi-Res Audio, so the design intent is detail retrieval — the small reverbs and subtle textures in a mix rather than just a loud, thumpy low end. Adaptive Active Noise Cancellation adjusts the level of noise reduction to your surroundings, which matters on a train, in a café, or on a flight where the noise floor changes constantly. The earpiece is an in-ear bud with a metal enclosure in white, and Samsung says the new fit is designed to stay put without constant readjusting — a real quality-of-life point if you've ever had buds loosen mid-walk.
Where it earns its keep is the ecosystem. Paired with a Galaxy S26 Series phone, you get HD Voice for clearer calls and hands-free AI assistance — quick answers and real-time translation delivered to your ears, plus Live Translate for breaking language barriers while traveling. Controls run through gesture, touch and voice, with Bixby and Google Assistant on tap. Bluetooth 6.1 with a 10-meter range covers normal room-to-room movement, and IP54 means splashes and dust aren't a problem. The wireless charging case and a 5-minute charge time for a top-up round out the package, and it ships as a US version with a 2-year manufacturer warranty.
Who should buy it: Anyone who wants one device for music, calls, travel and translation, especially if they already live in the Galaxy phone ecosystem. The AI and HD Voice features are the reason to choose it over a generic pair of earbuds.
Who should skip it: If you're on an iPhone or a non-Galaxy Android phone, you lose the headline AI features and the HD Voice pairing, and the value proposition drops fast. If you need all-day battery between charges, the 6-hour average life means you'll be docking them in the case regularly. And if you're a wired purist who refuses to deal with charging at all, this isn't the tool.
The 64 Audio Hi-Res Headphone Extension is a different category of product entirely. It's a 10-foot passive extension cable, not a listening device. The build is the story: Neutrik connectors, 3 cores carrying 44 pure copper wires at 22 AWG, and a braided nylon protective sleeve. The terminations are a Neutrik NP3RX-B ¼-inch TRS plug and a Rean NYS240BG ⅛-inch (3.5mm) TRS jack, with extra strain relief at both ends — the weak point on cheap cables is almost always right behind the connector, so that detail is worth noting. The female end carries 64 Audio branding, and the cable has an angled shape in black.
The number that stands out on the spec sheet is 0.4 Ohm of resistance. Over a 10-foot run, that's the difference between a cable that stays out of the way and one that colors or rolls off your signal. 64 Audio rates it as engineered for complete sonic transparency and matched to their own cable specifications. Practically, that means it's built for people who care about what reaches their ears, not just that something reaches them.
Compatibility is where it's aimed: personal monitor mixers from Behringer, Midas, Allen & Heath and Aviom, plus headphones and IEMs generally. Recommended uses are gaming, live performance, professional audio and studio recording, and it's listed for indoor use. It ships as a single extension cable in retail packaging.
Who should buy it: Studio engineers, live performers on in-ear monitor systems, gamers with a wired headset, and anyone whose headphone cable is simply too short for their desk or stage position. If you've been stretching a cable to its limit, this solves that without asking you to accept a degraded signal.
Who should skip it: If you want wireless freedom, this is the opposite of what you want — it's a cable, and a long one. If your gear uses USB-C, Lightning, or a 2.5mm/4.4mm balanced connector, check your terminations carefully, because this is a ¼-inch TRS to 3.5mm TRS design. And if you only listen on a phone with no wired output, there's nothing here for you.
• Best for wireless freedom → Samsung Galaxy Buds 4. Bluetooth 6.1, a 10-meter range and a charging case mean no cable tether at all.
• Best for signal integrity over distance → 64 Audio Hi-Res Headphone Extension. 44 pure copper wires, 22 AWG, 3 cores and 0.4 Ohm resistance are all about keeping the signal clean across 10 feet.
• Best for noise control → Samsung Galaxy Buds 4. Adaptive Active Noise Cancellation adjusts to your environment; the 64 Audio cable has no active electronics.
• Best for studio, stage and gaming runs → 64 Audio Hi-Res Headphone Extension. It's explicitly built for personal monitor mixers, live audio, studio work and gaming.
• Best for travel and translation → Samsung Galaxy Buds 4. Live Translate and hands-free AI assistance are core features, not add-ons.
• Best for rugged daily conditions → Samsung Galaxy Buds 4. IP54 handles splashes and dust; the 64 Audio cable is specified for indoor use.
• Best for durability under physical stress → 64 Audio Hi-Res Headphone Extension. Braided nylon sleeve plus extra strain relief at both ends targets the two failure points cables usually have.
• Best for pairing with a Galaxy S26 Series phone → Samsung Galaxy Buds 4. HD Voice and the AI features depend on that pairing.
• Best for people who already own wired headphones → 64 Audio Hi-Res Headphone Extension. It extends what you have instead of replacing it.
These two products barely compete — they solve opposite problems, and the honest answer is that most people should decide based on whether they want to cut the cord or extend it. In my opinion, if you're buying for yourself and you want one thing that does music, calls, noise cancellation, travel translation and hands-free AI, I'd buy the Samsung Galaxy Buds 4 — the feature set is broad and the IP54 rating plus 2-year warranty make it the more versatile everyday pick. I'd only steer you to the 64 Audio Hi-Res Headphone Extension if you already own wired headphones, IEMs or a personal monitor mixer and your real problem is reach, not features. In that specific case, the 0.4 Ohm resistance and Neutrik/Rean hardware make it the more purposeful buy. Cable people know who they are.
They can't be compared directly. The Buds 4 generate sound with a dynamic driver and support Hi-Res Audio. The 64 Audio cable produces no sound — it's designed to pass a signal through with as little alteration as possible, rated at 0.4 Ohm resistance.
No, they're Bluetooth earbuds and will pair with other devices. But the HD Voice calling and the AI assistant features are specified to work with the Galaxy S26 Series, so a non-Galaxy phone leaves some of the best features on the table.
Extending the reach of wired headphones, in-ear monitors or personal monitor mixers by 10 feet. It's recommended for studio recording, live performance, gaming and professional audio, and it's listed for indoor use.
No. It's a physical ¼-inch TRS to 3.5mm TRS cable with male and female ends, so it only works with wired gear that has a matching connection. For wireless listening, the Galaxy Buds 4 is the relevant product here.
That depends entirely on what you already own. The Buds 4 is a complete system — earbuds, charging case, ANC and AI features. The 64 Audio cable is a single-purpose accessory. Check the current price on Amazon for each and weigh that against how much of each product's capability you'll actually use.
