How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rugged, sleep-mode-aware hard shell that keeps a pair of Apple AirPods Max safe in a backpack, choose Yinke Case; if you need a tiny rechargeable amp that turns an electric guitar into a portable practice rig with a private headphone output, choose LEKATO Mini Guitar Amplifier. That's the whole decision in one line. One sells protection for a specific premium headphone; the other sells sound for a guitar. I'm framing this around portable headphones and around gear for children, because that's where most of the confusion happens — parents and gift-buyers keep landing on both listings and assuming they're alternatives. They aren't. They solve two completely different problems, and once you see that clearly, the right pick is obvious.
• Yinke Case — biggest strength: a tailored hard EVA shell with a 1:1 internal groove built specifically for AirPods Max, plus a design that lets the headphones enter sleep mode without the original Smart Case.
• Yinke Case — biggest trade-off: it does exactly one job. It protects AirPods Max. It makes no sound, and it fits nothing else.
• LEKATO Mini Guitar Amplifier — biggest strength: a genuinely portable 5W amp with dual speakers, Clean and Overdrive modes, a 2000mAh rechargeable battery, Bluetooth 5.0 and a 3.5mm headphone jack.
• LEKATO Mini Guitar Amplifier — biggest trade-off: it's a practice amp, not a hi-fi speaker or a headphone. It's built around guitar tone, so it won't satisfy someone shopping for headphones or a case.
• Who Yinke Case is for: AirPods Max owners who travel and want a shockproof, waterproof organizer.
• Who LEKATO Mini Guitar Amplifier is for: guitar, bass or mandolin players who want quiet, portable practice — including kids starting out.
The Yinke Case is a hard travel bag built around one device. The internal groove is a 1:1 match for AirPods Max, and the exterior measures roughly 23.5 x 21.0 x 6.3 cm, so it's a compact, purpose-shaped shell rather than a generic pouch. The shell material is EVA — the same family of foam used in a lot of protective gear — layered with foam and velvet. The lining is soft velvet with a point-shaped shockproof pattern, which is the detail that tells you the design intent: absorb bumps and drops instead of passing them straight through to the earcups.
Who should buy it: anyone who owns AirPods Max and moves around with them — commuting, school runs, flights, tossing a bag in a car. If your headphones live on a desk, you probably don't need it. If they ride in a backpack, you do. It's also waterproof, shockproof and anti-scratch, which matters more than people expect once a hard case is sharing space with keys, cables and water bottles. Note the age range listed is adult, so if you're buying for a child, treat this as an adult's case that a child might use under supervision rather than a kids' product. The compatible device size maxes out at 21.5 cm, which lines up with the AirPods Max form factor — nothing else.
Who should skip it: anyone who doesn't own AirPods Max. It's not a universal headphone case, and it won't fit over-ear brands with a different folding geometry.
LEKATO Mini Guitar Amplifier: Who It's For
The LEKATO Mini Guitar Amplifier is a different animal entirely. It's a 5W Class D amp with two output channels and built-in dual speakers, sized at roughly 6.3 x 4.3 x 3.52 inches. Small enough for a backpack, loud enough to be heard in a room. The retro woven threaded mesh front isn't just styling — it's there to let the dual speakers spread sound, and the listing claims surround-style output with full, powerful notes.
The control surface is deliberately simple: gain, tone and volume knobs, plus a one-key switch between Clean and Overdrive. That's a smart layout for practice. Clean gives you a clear, uncolored electric guitar or bass tone; Overdrive gives you the crunch. For a beginner — including a kid learning their first riffs — a single button that flips between those two is far less intimidating than a modeling amp with a menu system.
The battery is the headline number: a 2000mAh rechargeable cell, 2–3 hours to charge, up to 6 hours of play, charged over USB Type-C. LEKATO suggests a 5V 2A charger for faster charging. Six hours is genuinely a full practice week for most people, and it means no cable tethering to a wall while you play outdoors.
Then there's the 3.5mm headphone jack, and this is the part that connects directly to the headphone angle. Plug headphones in and the amp routes stereo output to your ears without disturbing anyone else. For a child practicing in an apartment, a shared bedroom or late at night, that one jack is the difference between "you can practice whenever you want" and "not after 8pm." It's also a 3.5mm audio input interface per the listing, so it doubles as your private monitoring path while you play or write.
Who should buy it: electric guitar, bass or mandolin players who want portable practice with a headphone option, and parents buying a first amp for a child. Who should skip it: anyone expecting a full-size gigging amp, a Bluetooth party speaker, or actual headphones.
Side-by-Side: Which Should You Choose?
• Best for protecting a premium headphone → Yinke Case. The EVA hard shell, velvet lining and 1:1 groove are built for exactly one job.
• Best for making sound → LEKATO Mini Guitar Amplifier. The Yinke Case is silent by design; it's a case, not a speaker.
• Best for quiet, late-night practice → LEKATO Mini Guitar Amplifier, via its 3.5mm headphone jack.
• Best for battery life → LEKATO Mini Guitar Amplifier, with its 2000mAh cell and up to 6 hours of play per charge.
• Best for travel durability → Yinke Case, which is waterproof, shockproof and anti-scratch.
• Best for a beginner or a child → LEKATO Mini Guitar Amplifier, thanks to the three-knob layout and one-key Clean/Overdrive switch.
• Best for AirPods Max owners specifically → Yinke Case, since nothing else in this comparison fits those headphones.
• Best for playing along to tracks → LEKATO Mini Guitar Amplifier, using Bluetooth 5.0 with a phone, tablet or PC.
If you're shopping for headphones themselves rather than a case or an amp — say you're comparing noise canceling open ear headphones for children, bluetooth earbuds for children, or sports earbuds for children — neither of these is that product. The Yinke Case only holds AirPods Max, and the LEKATO is an amplifier. Worth being clear about that before you buy.
My Verdict
If I had to pick one, I'd pick the LEKATO Mini Guitar Amplifier. In my opinion it does more for more people: it makes sound, it runs on a rechargeable battery for up to 6 hours, it connects over Bluetooth 5.0, and its headphone jack makes it genuinely usable for a child practicing without bothering the house. The Yinke Case is excellent at what it does, but what it does is protect one specific pair of headphones — and if you don't own AirPods Max, it has nothing to offer you. Buy the Yinke Case only if AirPods Max protection and sleep mode are the actual problem you're solving. Otherwise, for portable music-making and for children, the LEKATO is the one I'd take.
On a Mac, plug wired headphones into the 3.5mm jack or connect over Bluetooth from the sound menu. If you're using the LEKATO amp as your audio source, connect your headphones to its 3.5mm headphone jack instead — the listing states this jack delivers stereo output for private listening. That keeps your guitar tone in your ears and out of the room.
For wired mobile headphones, plug into the 3.5mm jack on your device or amp. For wireless ones, pair over Bluetooth. The LEKATO amp uses Bluetooth 5.0 to pair with a phone, iPad or PC, so you can stream backing tracks to the amp while your headphones stay plugged into the amp's 3.5mm jack.
USB-C headphones connect to a USB-C port on your device. The LEKATO amp charges over USB Type-C, and LEKATO recommends a 5V 2A charger — but that port is for charging the amp, not for audio input from headphones. For private listening, use the 3.5mm headphone jack.
For AirPods Max, the Yinke Case is the straightforward answer: the internal groove is a 1:1 fit, the EVA hard shell is shockproof and waterproof, and the design lets the headphones enter sleep mode while stored. The double zipper opens without pressure and the handle makes carrying easy — just close the shell fully before it goes in a bag.
