If you want to bring a pair of Bose (or JBL) headphones with a 2.5mm jack back to life on any device with a plain 3.5mm hole, choose EARLA TEC Replacement Audio Cable; if you need to plug wired 3.5mm headphones into a modern phone or tablet that only has USB-C, choose SXRBSSM USB C.
• EARLA TEC Replacement Audio Cable — biggest strength: a 1.4m oxygen-free copper cable with a 3.5mm to 2.5mm male-to-male layout built specifically for Bose QuietComfort QC25/QC35/QC35II/QC45/NC700 and several JBL models, so it restores the exact connection those headphones were designed around.
• EARLA TEC Replacement Audio Cable — biggest trade-off: it is a passive analog cord with no microphone, no remote, and no USB-C end — if your phone only has USB-C, this cable alone won't connect to it.
• SXRBSSM USB C — biggest strength: a two-pack of USB-C to 3.5mm adapters that lets standard 3.5mm headphones plug into USB-C phones, tablets and laptops, including iPhone 15/16/17 series, Galaxy S/S Ultra lines, Pixel, iPad Pro and MacBook.
• SXRBSSM USB C — biggest trade-off: it's an adapter, not a replacement cable — it doesn't fix a worn 2.5mm headphone cable, and the two-pack means you may only need one.
• Who each pick is for: pick EARLA TEC if you own 2.5mm-jack Bose/JBL headphones and need a fresh cord; pick SXRBSSM if you own normal 3.5mm headphones and a USB-C-only device.
The EARLA TEC cable exists to solve one very specific problem: your headphone's original cable wore out, got chewed, or vanished, and the headphone itself still works fine. It's a 3.5mm-to-2.5mm male-to-male auxiliary cord, about 1.4 meters long, in black. One end goes into the source (phone, laptop, console controller, MP3 player), the other into the headphone's smaller 2.5mm socket.
That 2.5mm end is the whole point. Bose's QuietComfort line — QC25, QC35, QC35II, QC45, NC700 — plus the OE2/OE2i and Soundlink/Soundtrue models, along with JBL E45BT, E55BT, E50, E35 and E30, use that narrower jack for wired listening. A normal 3.5mm cable physically won't fit. This one does, and the 24K gold-plated straight connectors plus oxygen-free copper construction are the kind of details that matter for a passive analog signal: fewer connection issues, no fuss, plug and play.
Who should buy it: anyone with the Bose or JBL headphones listed above whose cable has failed, and who wants a spare or a replacement without replacing the whole headset. It's also handy if you listen wired on a plane, at a desk, or through a PlayStation or Xbox controller with a 3.5mm jack. Who should skip it: if your headphones use a standard 3.5mm jack, if you need an inline mic for calls, or if your only audio source is USB-C — this cable doesn't solve any of those.
SXRBSSM USB C: Who It's For
The SXRBSSM adapter flips the problem around. New phones dropped the headphone jack; your wired headphones didn't. This two-pack of USB-C to 3.5mm adapters bridges the two, letting a regular 3.5mm headphone plug into a USB-C port. It's finished in a metallic gray, and the listing positions it as a Hi-Fi adapter.
The compatibility list is where this thing earns its place. It covers iPhone 17/17 Pro Max, 16/15 series, Google Pixel 7/7 Pro/6/6 Pro/6a, Samsung Galaxy S23/S23+/S23 Ultra and the S22/S21/S20 families, the A53 and A54, the W23/W22/W21, Z Flip 5/4/3/2 and Z Fold 5/4/3/2, plus MacBook Pro, MacBook Air 2020/M1/M2, iPad Pro 2022/2021/2020/2018, iPad Air 2020/2022 and iPad mini 2021. If you're carrying a modern USB-C phone, tablet or laptop and a pair of wired cans, this is the missing link.
Practical details: it's a passive adapter with no plug of its own (no power required), a single auxiliary port per unit, and two adapters in the pack. The 180-day warranty is stated on the listing. The two-pack format is genuinely useful — one for your bag, one for the desk — and it means a lost adapter isn't a crisis.
Who should buy it: anyone with 3.5mm headphones who moved to a USB-C phone, tablet or laptop and misses wired listening. It's also a clean fix for older wired earbuds you don't want to replace. Who should skip it: if your headphones use Bose's 2.5mm connector, this adapter won't fit them without the right cable; if your device still has a headphone jack, you don't need it; and if you specifically want an inline mic, check the setup rather than assuming.
• Best for reviving Bose or JBL headphones → EARLA TEC Replacement Audio Cable. The 2.5mm end is made for exactly those models.
• Best for USB-C phones with no headphone jack → SXRBSSM USB C. It's the adapter that lets normal 3.5mm headphones work again.
• Best for cable length → EARLA TEC Replacement Audio Cable. About 1.4m of usable reach versus a short adapter dongle.
• Best for multiple devices or sharing → SXRBSSM USB C. Two adapters in the pack cover a phone and a laptop at once.
• Best for durability-minded buyers → EARLA TEC Replacement Audio Cable. Oxygen-free copper and TPU sheathing built for daily bending and pocket life.
• Best for travel and portability → SXRBSSM USB C. A small metallic adapter takes up less room than a full cable.
• Best if you need a microphone → neither is the obvious pick. EARLA TEC is explicitly a no-mic cable; plan accordingly.
• Best all-round for a modern setup → SXRBSSM USB C. Most current phones and tablets are USB-C, so this solves the more common problem.
My Verdict
Yes — the listing names QuietComfort QC45, QC35II, QC35, QC25 and NC700, plus OE2/OE2i and Soundlink/Soundtrue. The 2.5mm end matches their wired jack.
The compatibility list includes iPhone 17/17 Pro Max, 16/15 Pro Max and 16/15 Pro, along with Galaxy S and Z series, Pixel, iPad Pro, iPad Air and MacBook. Check your exact model against that list.
Usually not. Buy EARLA TEC if your problem is a broken 2.5mm headphone cable; buy SXRBSSM if your problem is a USB-C device with no headphone jack. Only unusual setups need both.
No. The listing marks it "No mic," so it's for listening, not calls. Keep that in mind if you take a lot of voice calls wired.
