How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to drive wired, high-impedance headphones from almost any source with a clean, adjustable analog signal, choose MYPIN Headphone Amplifier; if you need true wireless earbuds with a charging case, long total playback and a waterproof, sport-ready fit, choose TAGRY Headphones True. These two products do not actually compete — one amplifies a wired signal, the other replaces the wire entirely — so the "versus" here is really about which job you have.
• MYPIN Headphone Amplifier — biggest strength: a HiFi amp stage with a two-stage gain switch, 16–300Ω headphone support, >100dB signal-to-noise ratio and 0.0003% THD+N, plus a 2000mAh battery rated for 12–15 hours.
• MYPIN Headphone Amplifier — biggest trade-off: it is fully wired (3.5mm in and out) and does not include a Lightning-to-3.5mm cable for iPhone, so you supply that yourself; there is also no wireless audio path in practice.
• TAGRY Headphones True — biggest strength: true wireless earbuds with a charging case that delivers up to 60 hours of total playback, a dual LED power display, wireless or USB-C charging, IPX5 water resistance and touch controls.
• TAGRY Headphones True — biggest trade-off: no wired jack and no active noise cancellation — the "noise control" field is listed as None, so isolation depends purely on the in-ear seal.
• Who each is for: MYPIN is for someone with demanding wired headphones and a weak source; TAGRY is for someone who wants cable-free listening for workouts, commutes and calls.
The MYPIN Headphone Amplifier (model HA0290-300) is a small analog problem-solver. Its job is to take a relatively weak 3.5mm line-level signal from a phone, MP3 player, computer, CD player or a console controller and push it through a proper amp circuit so a pair of headphones actually gets driven. The spec sheet tells the story: headphone impedance support from 16 to 300Ω, a signal-to-noise ratio above 100dB, and total harmonic distortion plus noise of 0.0003% (the description separately lists 0.004% distortion). Those numbers describe a clean, low-noise gain stage rather than a colored, bass-boosted toy.
The feature I find most interesting for real-world use is the two-stage gain switch. Rather than one blunt volume boost, it lets you match the amp's output to the headphone you're using — the difference between "louder" and "properly driven" is exactly the gap high-impedance cans fall into when plugged straight into a laptop or controller. A separate volume knob handles fine adjustment after that.
Battery life is the other practical headline: a 2000mAh (3.7V) rechargeable cell rated for more than 12–15 hours of use, recharged over USB. The shell is plastic, black, and described as lightweight, compact and sturdy — the kind of thing that lives in a bag pocket next to a portable player. It ships with a USB power cable, two 1m male-to-male audio cables and a user manual.
Buy it if you own wired headphones — especially higher-impedance ones — and your phone, laptop or PS5/Xbox controller just doesn't get them loud or clean enough. Skip it if you mostly listen wirelessly, or if you're an iPhone user who doesn't want to buy a separate Lightning-to-3.5mm cable, because that adapter is explicitly not in the box. Output power is listed at 40mW into 16Ω, so this is a portable listening amp, not a desktop powerhouse for the hardest-to-drive planars.
The TAGRY Headphones True (model X08) is a completely different category: true wireless in-ear buds with a charging case. The core pitch is endurance and convenience. Each earbud is rated for about 6 hours per charge, and the 470mAh case provides roughly four extra full charges, adding up to a claimed 60 hours of total listening. The case itself charges either wirelessly or over USB-C, and the dual digital LED display on the outside shows the power level for both the case and the buds — a small thing that genuinely removes guesswork before you leave the house.
Audio hardware is listed as 13mm dynamic drivers with triple-layer composite diaphragms, a 20Hz–20kHz range, 99dB sensitivity and 32Ω impedance. TAGRY's pitch is powerful bass with clear mids and treble, and the buds support both mono and twin stereo modes, so you can hand one to someone else or use a single bud for calls. Each earbud has a built-in microphone with CVC noise reduction aimed at making your voice clearer on calls.
On the physical side: Bluetooth 5, 10m range, touch controls on the earbuds for music, volume, calls and voice assistant, three sizes of ear tips, and IPX5 water resistance with a nano-coating to keep sweat and splashes out. A single earbud weighs just 0.14oz, and the case measures roughly 2.56 × 2.44 × 2.05 inches — small enough for a jeans pocket. A 5-year manufacturer warranty is noted in the product data.
Buy it if you want cable-free listening for running, gym sessions, commuting, calls and casual TV or laptop audio, and you hate charging things every day. Skip it if you need active noise cancellation (there is none — noise control is listed as None), or if you want a wired connection, because there is no headphone jack here at all.
• Best for driving high-impedance wired headphones → MYPIN Headphone Amplifier. The 16–300Ω support and gain switch exist precisely for this.
• Best for cable-free everyday listening → TAGRY Headphones True. True wireless with a pocketable case and no cords anywhere.
• Best for long listening sessions away from a charger → TAGRY Headphones True. Up to 60 hours total via the case beats MYPIN's 12–15 hours per charge.
• Best for a clean, low-noise analog signal chain → MYPIN Headphone Amplifier. >100dB SNR and 0.0003% THD+N are the relevant figures.
• Best for workouts and sweaty environments → TAGRY Headphones True. IPX5 water resistance and a lightweight in-ear fit; MYPIN is a plastic amp you'd keep dry.
• Best for gaming controllers and older players → MYPIN Headphone Amplifier. MP3, MP4, computer, CD player and PS4/PS5/Xbox controller support are all listed.
• Best for phone calls and voice assistant use → TAGRY Headphones True. Built-in mics with CVC noise reduction and touch controls.
• Best for a shared-listening moment → TAGRY Headphones True. Mono mode lets you pass one earbud to a friend; an amp can't do that.
• Best if you want to spend nothing extra on accessories → MYPIN Headphone Amplifier ships with its audio cables, though iPhone users still need their own Lightning adapter.
In my opinion, these aren't substitutes, so I'd pick based on the headphones you already own. If you have a pair of wired cans that sound thin or quiet straight out of your phone, laptop or controller, I'd buy the MYPIN Headphone Amplifier — the gain switch, the impedance range and the noise figures are exactly the right tool for that job, and the 12–15 hour battery makes it genuinely portable. If you want freedom from cables, long total playback and something you can sweat on, I'd buy the TAGRY Headphones True instead; just accept that there's no ANC and no wired fallback. Own both use cases? They coexist happily — one for serious wired listening, one for everything else. Check the current price on Amazon before deciding, since that's the one variable this comparison can't cover.
FAQ
No. The noise control field is listed as None, so there's no active noise cancellation. Isolation comes from the in-ear seal with the included ear tips, which is why they're a reasonable choice for sports and commuting but not for blocking out a plane cabin.
Yes, but you'll need to supply your own Lightning-to-3.5mm cable — it's not included. The box contains the amp, a USB power cable, two audio cables and a manual, and the amp works with 3.5mm sources generally, including computers and console controllers.
MYPIN's 2000mAh battery is rated for more than 12–15 hours of continuous use. TAGRY's earbuds run about 6 hours per charge, and the 470mAh case adds roughly four more full charges, for up to 60 hours total before you need a wall outlet.
