How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single cable that turns one pair of wired studio headphones into a long-reach, adapter-ready tool for TV watching, choose Toxaoii Replacement Audio Cable; if you need the actual closed-back headphones you plug that cable into for mixing, tracking and monitoring, choose StreamEye Cans50. These are two different products solving two different problems — one is a replacement cord, the other is a full set of studio cans — so the only useful question is which gap you're trying to close in your setup, especially if your goal is comfortable, isolated TV watching at night.
• Toxaoii Replacement Audio Cable — biggest strength: broad compatibility with a long list of Beyerdynamic and AKG models, plus a coiled cable that stretches from 4.6 ft to 13.4 ft.
• Toxaoii Replacement Audio Cable — biggest trade-off: it's a cable only — no earcups, no drivers, no sound of its own, and the earphones are not included.
• StreamEye Cans50 — biggest strength: closed-back over-ear design with 50 mm dynamic drivers, 15 Hz–25 kHz response and 32 ohm impedance for monitoring and mixing.
• StreamEye Cans50 — biggest trade-off: it's a wired-only headphone with a single included 3.5 mm cable, so cable length and reach are whatever the stock cord gives you.
• Who each pick is for: Toxaoii for anyone whose existing compatible headphones have a failed or too-short cable; StreamEye for anyone who needs the headphones themselves for studio or DJ work.
This is a repair-and-upgrade part, and it's honest about that. The Toxaoii cable is built to fit a specific family of headphones: Beyerdynamic DT 1990 Pro, DT 1770 Pro, DT 990 Pro, DT 990 Pro X, DT 770 Pro and DT 770 Pro X, plus a long list of AKG models including the Q701, Q702, K712, K240 family, K271 family, K141, K171, K181, K175, K275 and more. If your model is on that list, this is a drop-in replacement rather than a gamble.
Who should buy it: anyone whose compatible Beyerdynamic or AKG headphones still sound fine but whose cable has gone crackly, too short, or tangled beyond saving. Who should skip it: anyone who doesn't already own a compatible headphone — remember, the earphones are not included, and this cable won't make a non-listed model fit. Also skip it if you want wireless; this is an AUX cable, full stop.
StreamEye Cans50: Who It's For
The Cans50 is the other half of the equation — the headphones themselves. StreamEye built these as closed-back over-ear monitoring cans, and the design choices all point at studio work. The closed-back earcups block external noise and stop audio bleeding out, which is exactly what you want when tracking vocals in a shared room or mixing in a space where open-back leakage would ruin your take. The 50 mm dynamic drivers cover a 15 Hz–25 kHz range, and at 32 ohm impedance with 95 dB sensitivity they're easy to drive from an interface, mixer, amp or DJ controller.
Comfort is clearly a design priority. The ear cushions are soft and breathable, the headband is adjustable, and the earcups rotate 90 degrees and fold flat — which helps both with fit across head sizes and with tossing them in the included soft bag. The package also includes a 1/4" adapter for plugging into pro gear, and there's a 1-year warranty.
Who should buy it: audio engineers, home studio producers, musicians, DJs and drummers who need isolation and accurate monitoring without spending studio-tier money. Who should skip it: anyone who wants Bluetooth or spatial audio — this is a wired 3.5 mm headphone with an adapter, no drivers required but also no wireless option. If you were hunting for open ear earbuds for TV watching or best sports earbuds for TV watching, this isn't that category at all; it's a wired monitoring tool.
Side-by-Side: Which Should You Choose?
• Best for replacing a broken or too-short cable → Toxaoii Replacement Audio Cable. If your DT 770 Pro or AKG K240 cord is the problem, this fixes it directly.
• Best for actual mixing and monitoring → StreamEye Cans50. Closed-back isolation plus 50 mm drivers and a 15 Hz–25 kHz range is built for critical listening.
• Best for tracking in a shared room → StreamEye Cans50. Closed-back earcups prevent bleed, which open-back designs can't do.
• Best for adapting to pro gear → both, honestly. Toxaoii ships a screw-on 6.35 mm adapter; the Cans50 includes a 1/4" adapter. Either way you can go from 3.5 mm to a mixing desk.
• Best for comfort over long sessions → StreamEye Cans50. Breathable cushions, adjustable headband and rotating, fold-flat earcups.
• Best for travel and storage → StreamEye Cans50. The included soft bag plus folding cups beat a bare cable in a pocket.
• Best for people who own nothing compatible yet → StreamEye Cans50. Buying the cable first only makes sense if you already have a listed headphone.
In my opinion, the right pick depends entirely on which hole you're patching. If you already own a compatible Beyerdynamic or AKG headphone and your real frustration is a short, failing cord — especially for TV watching from the sofa — I'd buy the Toxaoii Replacement Audio Cable, because 13.4 ft of reach plus the 6.35 mm adapter solves a problem no new headphone needed to solve. If you don't own studio headphones yet, or you need isolation for mixing and tracking, I'd buy the StreamEye Cans50 and treat the cable question later. For TV watching specifically, my honest read is that the cable is the smarter buy for most people who already have the cans.
how to connect studio headphones
Plug the 3.5 mm jack into your device, or screw on the 6.35 mm / 1/4" adapter for a console, amplifier, interface or mixing desk. The StreamEye Cans50 includes both a 3.5 mm cable and a 1/4" adapter, and the Toxaoii cable ships with a screw-on 6.35 mm adapter. No drivers are required for the Cans50 on Mac or Windows.
how to test studio headphones
Play a familiar track and listen across the range — the Cans50 covers 15 Hz–25 kHz, so check whether lows, mids and highs all come through cleanly. Check both earcups for balance and any rattle, and confirm the cable connection is solid at the jack. On a closed-back design like the Cans50, you can also confirm isolation by cupping the earcups and noting how much outside noise drops.
how to bluetooth studio headphones
Neither product here is wireless. The StreamEye Cans50 is a wired over-ear headphone using a 3.5 mm jack with an included 1/4" adapter, and the Toxaoii is an AUX replacement cable. To go Bluetooth you'd need a separate transmitter or a different headphone entirely — these two are wired-only by design.
can you mix with just headphones
Yes — the Cans50 is explicitly built for it, with closed-back isolation, 50 mm dynamic drivers and a 15 Hz–25 kHz response aimed at monitoring and mixing in a DAW. The catch is that headphones can't reveal room acoustics the way monitors do, so treat them as your primary reference only if you know their character well. The closed-back design does at least keep outside noise from skewing what you hear.
