If you want a simple, kid-friendly pair of wired on-ear headphones you can fold up and toss in a bag, choose ELECDER i45; if you need a portable USB-C DAC/headphone amp to squeeze real hi-res sound out of a phone or laptop, choose BZINK BA36. These two sit in completely different corners of the "portable headphones" world, and that is exactly why comparing them is useful. One is a headphone. The other is the hardware that makes your existing headphones sound better. If your goal is jogging with a lightweight, affordable pair you do not have to baby, the i45 is the one that fits the job. If your goal is better audio from a USB-C device, the BA36 is the tool you want.
• ELECDER i45 biggest strength: A genuinely portable, foldable on-ear wired headphone with an adjustable headband, a 1.5M 3.5mm cord, and a 40mm dynamic driver — plug it into almost anything with a headphone jack and go.
• ELECDER i45 biggest trade-off: It is wired, has no volume buttons, and needs an adapter for newer iPhones and USB-C-only devices. Sound isolation is passive, so it will not block out a noisy commute.
• BZINK BA36 biggest strength: A dual-chip USB-C DAC/amp (CS43131 + SGM8262) with 32bit/384kHz decoding and up to 227mW output, able to drive headphones from 16Ω all the way to 600Ω.
• BZINK BA36 biggest trade-off: It is not a headphone at all. You still need your own wired headphones, and it only works with USB-C sources — no 3.5mm input, no Bluetooth.
• Who the ELECDER i45 is for: Students, kids over 8, and casual listeners who want a cheap, foldable, no-fuss wired pair for school, travel, or a light jog.
• Who the BZINK BA36 is for: Audiophiles, gamers, and mobile listeners who already own good wired headphones and want cleaner, louder, more detailed sound from a USB-C phone, tablet, or laptop.
The i45 is a wired on-ear headphone built around simplicity. It uses a 40mm dynamic driver with a 20Hz–20,000Hz frequency range, 32 ohm impedance, and 95dB sensitivity. That combination is easy to drive — plug it into a smartphone, Chromebook, PC, tablet, Kindle, or airplane seat jack and it will play without any special hardware. The 1.5M cord gives you enough slack to move around a desk or tuck the phone in a pocket while you walk.
Who should buy it? Anyone who wants a low-cost, durable-feeling wired pair that just works with a headphone jack. Kids and teens heading to class, a spare pair for a laptop, or a travel headphone you are not afraid to lose. In my opinion it is also a reasonable pick for light jogging on a treadmill or a quiet path, because the on-ear fit and folding build keep it compact and the wired connection means no charging. The 1-year warranty and 24/7 email support round out the package.
Who should skip it? If you want Bluetooth, active noise cancellation, or built-in volume controls, this is not that product — the i45 has no volume buttons, so you adjust volume on the device. If you own an iPhone 7, iPad Pro 11, or any newer USB-C-only device, you will need a Lightning-to-3.5mm or USB-C-to-3.5mm adapter that is not included. And if you need serious isolation on a loud train, look elsewhere.
BZINK BA36: Who It's For
The BA36 is a different category entirely: a USB-C portable DAC and headphone amplifier, not a headphone. Inside is a dual-chip setup — CS43131 plus SGM8262 — that decodes up to 32bit/384kHz and delivers up to 227mW at 32Ω. It supports headphones from 16Ω to 600Ω, which means it can drive sensitive in-ear monitors without hiss and still push high-impedance over-ears that a phone's built-in output would struggle with. The signal specs are where the audiophile pitch lives: greater than 125dB SNR/DNR and -110dB THD+N, which translates to a very quiet background and low distortion.
Build and portability are clearly priorities. The shell is aluminum alloy, and the cable is silver-plated oxygen-free copper for better signal transmission. At 37.65 grams it is light enough to hang off a phone in your pocket, and the compact dongle format is designed for travel, commuting, gaming, and studio use. Installation is plug-and-play — no drivers. It works with iPhone 15 series, Android phones, iPads, tablets, and laptops that have a USB-C port. BZINK also includes a USB-A adapter in the box, which helps if you want to use it with a computer that only has a USB-A port.
Who should buy it? If you already own a good pair of wired headphones or IEMs and you feel like your phone or laptop is holding them back, this is the upgrade path. Gamers who want cleaner positional audio, commuters who want more headroom on quiet tracks, and anyone moving to a USB-C phone with no headphone jack. The 20-month warranty and 24/7 email support are a nice safety net.
Side-by-Side: Which Should You Choose?
• Best for jogging → ELECDER i45. A lightweight on-ear wired set with an adjustable headband, no battery to worry about, and a compact fold — though for hard running you may prefer a secure in-ear design.
• Best for real hi-res audio → BZINK BA36. Dual CS43131 + SGM8262 chips, 32bit/384kHz decoding, and 227mW of output power.
• Best for driving demanding headphones → BZINK BA36. The 16Ω–600Ω range covers everything from sensitive IEMs to high-impedance over-ears.
• Best for kids and students → ELECDER i45. Adjustable headband, recommended for ages 8 and up, and a simple 3.5mm plug for school devices.
• Best for travel and packing → ELECDER i45. It folds to roughly 6 x 4.53 x 2.87 inches; the BA36 is a 37.65g dongle that rides in a pocket.
• Best for USB-C-only phones → BZINK BA36. Plug-and-play with iPhone 15 series, Android, iPad, tablets, and laptops over USB-C.
• Best for old-school 3.5mm sources → ELECDER i45. The 1.5M aux cord works with phones, Chromebooks, PCs, and airplane jacks without adapters.
• Best for a quiet, distortion-free signal chain → BZINK BA36. >125dB SNR/DNR and -110dB THD+N are aimed squarely at clean output.
If I am buying one thing and I want to actually listen on the move — including a light jog — I would pick the ELECDER i45. It is a complete, self-contained headphone: foldable, adjustable, wired, and ready for a phone, laptop, or plane. In my opinion it is the smarter first purchase for most casual listeners, students, and parents. I would only choose the BZINK BA36 if I already had good wired headphones and a USB-C source and wanted to unlock their potential. It is the better audio tool, but it is not a headphone — so it only makes sense as an upgrade, not a starting point.
FAQ
The BZINK BA36 is the relevant product here: it is a USB-C to 3.5mm DAC adapter, so you plug it into the USB-C port and connect your wired headphones to the 3.5mm end. It is plug-and-play with no drivers and works with iPhone 15 series, Android, iPad, tablets, and laptops that have USB-C. The ELECDER i45 is analog 3.5mm only, so it needs an adapter to reach a USB-C device.
The ELECDER i45 folds, packing down to roughly 6 x 4.53 x 2.87 inches, which makes it easy to slide into a backpack or carry-on. The BZINK BA36 is not a headphone but a 37.65g dongle with a short cable, so it simply coils into a pocket or accessory pouch.
The BZINK BA36 works with laptops that have a USB-C port — plug it in, then connect your wired headphones to its 3.5mm jack for cleaner, louder output. The ELECDER i45 is even simpler on a Mac that still has a 3.5mm jack: just plug the cord in. On newer Macs without a 3.5mm port, you would need a USB-C-to-3.5mm adapter for the i45.
