• Mr Rex 2.5mm — biggest strength: it is a purpose-built replacement aux cord with an inline mic and volume control, aimed at headphones that use a 2.5mm jack (Bose 700, QuietComfort QC45/QC35II/QC35/QC25, and a long list of JBL and AKG models).
• Mr Rex 2.5mm — biggest trade-off: it is a cable only. If you need earbuds or a full headset, this does not give you one, and it will not fit headphones with a standard 3.5mm port or brands like Sennheiser and Audio-Technica.
• yobola Headphones Earbuds 3.5mm — biggest strength: an all-in-one in-ear solution with a built-in mic, inline remote for calls, volume, play/pause and track skipping, and a standard 3.5mm plug that fits phones, tablets, computers and MP3/MP4 players.
• yobola Headphones Earbuds 3.5mm — biggest trade-off: it is a fixed in-ear design with a 4.2ft cable, so there is no swapping cables or reaching across a room, and no replaceable parts.
• Who each is for: Mr Rex 2.5mm is for someone who already owns 2.5mm-jack over-ear headphones and needs to restore them; yobola is for someone who wants a fresh, ready-to-use set of wired earbuds with a mic.
Mr Rex 2.5mm is a repair-and-restore product, not a listening product. If your Bose 700, QC45, QC35II, QC35 or QC25 has a cable that has frayed, crackled, or gone missing, this is the part that puts the headphones back in service. The 2.5mm plug is the end that goes into the headphone itself, while the 3.5mm end goes into your phone, laptop, PS4 or Xbox controller, computer or MP3 player. That two-ended design is the whole point: it bridges older premium headphones to modern 3.5mm sources.
The build details matter for daily wear. The connectors and the microphone control box sit inside zinc alloy casing, which is a sturdier choice than plain plastic for something that gets yanked in and out of a bag. The jack is gold-plated and the inner wire is OFC (oxygen-free copper), which is the standard recipe for keeping signal transfer clean. The 3.5mm connector is set at a 135-degree angle — a small design decision that reduces strain right at the point where cables usually fail first. At 5 feet, it is longer than many stock cables, so you can move around a desk or couch without tugging. A Velcro strap is included, plus the cable is described as braided and tangle-free.
yobola Headphones Earbuds 3.5mm: Who It's For
yobola Headphones Earbuds 3.5mm is the opposite kind of purchase: a complete, self-contained set of wired in-ear earphones. There is nothing to assemble or replace. You plug the 3.5mm jack into an iPhone, iPad, Samsung phone, computer, or MP3/MP4 player and you are listening. The in-ear placement and ABS/polycarbonate housing are built for a lightweight, pocketable everyday carry, and the white 3.5mm styling keeps it simple.
The headline feature is the inline control and mic setup. The cord carries a built-in microphone with noise reduction aimed at clearer calls, plus an inline remote that handles answer/end, play/pause, track skipping and volume — all without pulling your phone out. That single detail is what makes these earbuds genuinely useful for commuting, school, travel, and any hands-free call situation. On the audio side, the specs list a 32 ohm impedance and a 20–20000Hz frequency range with a dynamic driver, which is a normal, sensible load for phones and laptops to drive directly. Sound isolation is listed as a noise control feature, which is what you would expect from an in-ear fit that seals the ear canal.
Who should buy it: students, commuters, call-heavy workers, and anyone who wants one cable to do music plus phone calls on a 3.5mm device. It also comes with a 1-year warranty. Who should skip it: people who dislike in-ear tips, anyone who needs a longer cable than 4.2ft, and anyone shopping for a replacement cable rather than new earphones — the jack here is fixed 3.5mm and will not fit a 2.5mm headphone port.
Side-by-Side: Which Should You Choose?
• Best for reviving existing Bose/JBL/AKG headphones → Mr Rex 2.5mm. The 2.5mm plug only exists to serve those headphone jacks.
• Best for plug-and-play out of the box → yobola Headphones Earbuds 3.5mm. No assembly, no compatibility guessing beyond a 3.5mm port.
• Best for hands-free calling → yobola Headphones Earbuds 3.5mm. Its inline remote covers answer/end, play/pause, track skip and volume in one place.
• Best for reach and movement → Mr Rex 2.5mm. At 5 feet it is longer than the 4.2ft yobola cable, which matters at a desk or on a couch.
• Best for a tidy setup → Mr Rex 2.5mm. A Velcro strap is included and the cable is described as braided and tangle-free.
• Best for school, travel and light carry → yobola Headphones Earbuds 3.5mm. In-ear earbuds pack smaller than a coiled 5ft cable and don't need an existing headphone to be useful.
• Best for a device without a 3.5mm port → neither, without an adapter. Mr Rex needs a Lightning/USB-C to 3.5mm adapter for such phones, and yobola's plug is 3.5mm as well.
In my opinion, these two products are not really rivals — they solve different problems, so the honest answer is to buy the one that matches your situation. If you already own 2.5mm-jack Bose, JBL or AKG headphones and the cable is the only thing wrong, I would buy Mr Rex 2.5mm. It is cheaper in spirit than replacing headphones, the compatibility list is specific and broad, and the angled gold-plated jack plus zinc alloy housing is the right design for a part that takes abuse. If you need earphones with a mic for calls, school and travel, I would buy yobola Headphones Earbuds 3.5mm instead — it works the moment you unbox it, on any device with a 3.5mm port.
If you are still weighing it up, check the current price on Amazon for each before deciding, since that is the one variable that could tip a close call.
what is an inline mic on headphones
An inline mic is a small microphone built into the headphone cable itself, usually inside the little control pod on the cord rather than on the earcup. Both products here have one: Mr Rex 2.5mm puts it in the zinc alloy control box on the replacement cable, and yobola builds it into the inline remote on its earbuds cord. It lets you take calls without holding your phone.
how to use wired headphones with mic on pc
Plug the 3.5mm end into your PC's headphone or combo audio jack, then select that device as the input and output in your sound settings. Mr Rex 2.5mm works this way if you are using 2.5mm-jack headphones with a 3.5mm port on the computer, and yobola's 3.5mm plug connects the same way. If your PC has separate mic and headphone jacks, you may need a splitter.
Only if your headphones have a 2.5mm jack port. The list covers Bose 700, QuietComfort QC45, QC35II, QC35 and QC25, plus JBL models like E45BT, E55BT, E65BTNC, Tune and Everest series, and AKG models including Y400, Y500, Y50BT and Y600NC. It is explicitly not for Sennheiser or Audio-Technica headphones, and it will not fit standard 3.5mm ports.
Yes, as long as your iPhone has a 3.5mm headphone jack — the earbuds use a standard 3.5mm plug. Newer iPhones without a 3.5mm port need a Lightning to 3.5mm adapter, which is not included. The inline remote and mic handle calls, volume and track control once connected.
