• Callez 3.5mm — biggest strength: A mono, on-ear headset weighing just 56g, with a flexible headband, a 330° rotatable noise-cancelling mic and a 2-year worry-free guarantee. Built for talk, not for music.
• Callez 3.5mm — biggest trade-off: It ships with a 3.5mm jack plus a USB-C adapter, and it is not compatible with iPhone 7/8/X/XS/XR/11/12/13/14. One ear only, so it is a poor fit for immersive listening.
• BLXSounds 2 — biggest strength: A 2-pack of in-ear USB-C earbuds with a 14.2mm dynamic driver and an upgraded DAC chip, aimed at clear digital audio with no buzzing or popping.
• BLXSounds 2 — biggest trade-off: It is USB-C only with no 3.5mm option and no adapter mentioned, so older 3.5mm-only devices are out. The included warranty is 1 year versus Callez's 2.
• Who each pick is for: Callez 3.5mm for call-heavy workers, students and classroom or call-center use; BLXSounds 2 for listeners who want two pairs of music-first earbuds for USB-C phones, tablets and laptops.
The Callez 3.5mm is a purpose-built communications headset. It is a monaural on-ear design in gray, with a leatherette ear cushion, a metal-and-plastic build and a circular earcup. At 56g (1.97oz) it is genuinely light, and the adjustable headband can be bent or shaped to fit different head sizes — Callez's own framing is that this relieves pressure during long wear. The mic rotates up to 330° so you can park it on the left or right side depending on how you work. The driver is a 32-ohm dynamic unit covering 20Hz–20KHz, and there are simple in-line button controls for volume plus answer/end/reject on a call.
The connectivity story is the practical part. It terminates in a 3.5mm jack and includes a USB Type-C to 3.5mm headset adapter, which means one headset can move between a laptop, a tablet and a current phone. Callez lists support for iPhone 15/16/17 families, iPad Pro/Air/Mini 6, MacBook Pro/Air, and Galaxy S21 through S25, plus any device with either jack. The explicit warning matters: it will not work with iPhone 7, 8, X, XS, XR, 11, 12, 13 or 14. Setup is plug-and-play — no drivers, no app.
So who should buy it? In my opinion, this is the right pick if your day is meetings. Zoom calls, Skype, conference lines, call-center shifts, online classes, working from home with a softphone — that is the target. The mono earcup keeps one ear open to your room, the boom mic sits where you want it, and the in-line buttons mean you can mute or hang up without touching your computer. The 45-day money-back window and 2-year guarantee are a reasonable safety net for something you will wear daily. The included bundle is practical too: cable, ear cushions, headband, headset and a user manual.
Who should skip it? Anyone shopping for music. A single on-ear cup with a mono signal is not how you want to hear a record, and a 3.5mm analog headset will not match the digital signal path of a native USB-C earbud. Also skip it if you are still on an iPhone 7 through 14, or if you want true stereo separation in both ears. And if you dislike on-ear pressure entirely, an in-ear design will suit you better.
The BLXSounds 2 is a different animal: a 2-pack of black in-ear USB-C earphones, model TC-EASC17. The pitch is audio quality first. It uses a 14.2mm dynamic driver and an upgraded DAC chip to handle digital input signals, which is how it claims to keep high-resolution acoustics intact and avoid buzzing, popping or other artifacts. In plain terms: the earbuds do the digital-to-analog conversion themselves, so the sound you get depends on the earbud rather than on whatever DAC happens to be in your phone or laptop dongle. That is a real advantage on devices with a weak built-in output.
The design is ergonomic in-ear with lightweight materials, and the product page emphasizes comfort over long sessions — long wear without pain, which is the usual complaint about cheap in-ears. There is a multifunction remote control on the cable for playback and calls, noise isolation from the sealed fit, and a durable construction claim. The listing also names iPhone 17/16/15, Android, Galaxy S25/S24 Ultra and Pixel as target devices, and it is wired with a Type-C connector. The title mentions a clear mic and noise reduction, so it is intended to work for calls as well as music. You get two units in the box and a 1-year warranty.
Who should buy it? Anyone who listens more than they talk. Music streaming, gaming, sport, commuting, a second pair for a bag or desk — the 2-pack is the headline feature here, because you can keep one at home and one at work and stop unpacking your bag every morning. If your phone, tablet or laptop is USB-C and you want plug-and-play digital audio without a dongle, this is the shape of product you want. The in-ear seal also helps in noisy rooms for casual listening.
Who should skip it? Anyone whose devices are still 3.5mm-only — there is no adapter mentioned in the data, and no analog option. Skip it if you want a boom mic for hours of video meetings; a cable remote is fine for occasional calls but it is not a headset mic. And skip it if you specifically want an open, one-ear design to stay aware of your surroundings.
• Best for long calls and meetings → Callez 3.5mm. Mono on-ear cup, 330° boom mic, in-line volume and call controls, 56g.
• Best for music, gaming and streaming → BLXSounds 2. 14.2mm dynamic driver and an upgraded DAC chip for a clean digital signal.
• Best for mixed device fleets → Callez 3.5mm. 3.5mm jack plus an included USB-C adapter covers laptops, tablets and modern phones.
• Best for USB-C-only setups → BLXSounds 2. Native Type-C, no dongle, no adapter to lose.
• Best for all-day comfort while talking → Callez 3.5mm. Adjustable, bendable headband and leatherette cushion designed for long wear.
• Best for two people or two locations → BLXSounds 2. It is sold as a 2-pack, so you get a spare pair out of the box.
• Best warranty coverage → Callez 3.5mm. 2 years plus a 45-day money-back window, against 1 year for BLXSounds 2.
• Best for iPhone 7–14 owners → neither as listed. Callez explicitly excludes those models, and BLXSounds 2 targets USB-C iPhones.
I would buy the Callez 3.5mm. The reason is not that it sounds better — it is that it solves a harder problem. If you spend your working day on Zoom, Skype or a softphone, a 56g on-ear headset with a rotatable noise-cancelling boom mic, in-line call controls, both 3.5mm and USB-C connectivity and a 2-year guarantee covers more of your day than a pair of earbuds will. The mono cup and open design also mean you stay aware of your surroundings, which matters at home and in a shared office. I would only switch to the BLXSounds 2 if music, gaming and personal listening are the actual priority — in that case the digital USB-C connection, 14.2mm driver and spare second pair make it the better fit. Check the current price on Amazon before you commit, since that is the one thing that can flip this decision.
FAQ
Yes. Callez lists support for the iPhone 15, 16 and 17 families plus iPad and MacBook, using the included USB-C to 3.5mm adapter. It explicitly does not work with iPhone 7, 8, X, XS, XR, 11, 12, 13 or 14.
No. The BLXSounds 2 is a USB-C wired earbud with a Type-C connector and no 3.5mm option or adapter listed. If your laptop or phone only has a round headphone jack, it will not connect.
The Callez 3.5mm, in my opinion. It has a dedicated 330° rotatable noise-cancelling boom mic, an in-line control for volume and answer/end/reject, and a lightweight on-ear build made for long meeting days. The BLXSounds 2 has a cable remote, which is fine for occasional calls but not a headset mic.
Callez offers a 45-day money-back window and a 2-year worry-free guarantee. BLXSounds 2 lists a 1-year warranty. Both cover the product itself; neither figure reflects price, which you should confirm on Amazon.
