• Stouchi 2-in-1 biggest strength: One compact adapter that splits your USB-C port into charging plus a real 3.5mm headphone jack, with a Hi-Res DAC rated up to 24bit/96KHz and PD charging up to 9V/3A (30W).
• Stouchi 2-in-1 biggest trade-off: It only works with headphones you already own, and it ties you to a cable. There is no battery, no case, and no wireless freedom.
• Flecom iPhone 17 biggest strength: True wireless earbuds with a charging case, Bluetooth 5.3, an LED battery display, up to 48 hours with the case, and an IPX7 waterproof rating.
• Flecom iPhone 17 biggest trade-off: No 3.5mm jack and no charging passthrough for your phone. You are fully dependent on the earbuds' own battery.
• Pick Stouchi 2-in-1 if you love your wired earphones and hate choosing between charging and listening.
• Pick Flecom iPhone 17 if you want cord-free listening for workouts, commutes and calls, and you do not mind managing a case.
The Stouchi 2-in-1 is a problem-solver for a very specific frustration. Modern phones dropped the headphone jack, and once you plug in a USB-C to 3.5mm dongle, your charging port is gone. Stouchi's answer is a single mini adapter with two ports: one for your charger, one for your 3.5mm earphones. The model number is Y5, and the brand leans hard on the "2 in 1" idea — charge and listen at the same time, plug and play, no software to install.
The technical pitch is stronger than a typical cheap dongle. The built-in PD chip pushes charging power up to 9V/3A, which the spec sheet translates as 30W fast charging. On the audio side, the DAC supports up to 24bit/96KHz and works with both CTIA and OMTP headphone wiring standards. In plain terms: your wired earphones should sound like wired earphones, not like a degraded afterthought, and the adapter is not picky about which headset pin layout you own. The jack supports headphones, and the product is listed for use with cell phones, headphones and speakers.
Compatibility is the real selling point here. Stouchi lists iPhone 17, 16 and 15 series, iPad Air and iPad Pro, a long run of Samsung Galaxy phones from the S10 era up through the S25 family, Note models, Z-Flip, Google Pixel 2 through Pixel 9, and Huawei P40 and Mate 40 devices. If your phone has USB-C and you own a decent pair of wired headphones, this adapter is aimed at you.
Who should skip it? If you have already moved to wireless earbuds and never touch a 3.5mm plug, this does nothing for you. And if you want zero cables in your life, a 2-in-1 adapter is the opposite of that. Stouchi backs it with lifetime technical support, which is a reassuring note for a small accessory that lives in a pocket.
Flecom iPhone 17: Who It's For
The Flecom iPhone 17 is the other philosophy entirely: cut the cord. This is a set of true wireless in-ear earbuds, model S53, that arrive with a charging case, a USB-C cable and a user manual. Take them out of the case and they reconnect automatically after the first pairing. The connection runs on Bluetooth 5.3, which is the current mainstream standard for stable links and clear call audio.
Battery is the headline. Flecom lists up to 48 hours of total playtime with the charging case, and the case itself recharges over Type-C in about two hours. The battery spec sheet also mentions 50 hours of average life, and there is an independent LED display on the case that shows battery level and charging status in real time. That is genuinely useful — you can see how much juice is left before you leave the house instead of guessing. One honest note from the manufacturer: charge the earbuds fully before first use.
Comfort and durability look thoughtful. The earbuds use an ergonomic in-ear shape and ship with three ear tip sizes so you can get a proper seal even with smaller ears. The earpiece shape is in-ear, the housing is ABS plastic, and the whole thing is white. Each earbud weighs about 4.54 grams, so they are light enough to forget you are wearing them. The IPX7 rating means they handle sweat and splashes, which matters for workouts and rainy commutes.
Controls are touch-based, covering play and pause, answering and rejecting calls, volume, track switching and voice assistants. The audio driver is a balanced armature type, and the earbuds include active noise cancellation. Compatibility covers iPhone 17 Pro Max, 17 Pro, iPhone Air, 16 series and 15 series, plus a wide spread of Samsung Galaxy models including the S26, S25 and A-series, and Google Pixel devices.
Side-by-Side: Which Should You Choose?
• Best for keeping wired headphones → Stouchi 2-in-1. It is the only one of the two with a real 3.5mm jack.
• Best for charging while listening → Stouchi 2-in-1. Two ports, one for power and one for audio, up to 9V/3A.
• Best for audio specs on paper → Stouchi 2-in-1. A DAC rated to 24bit/96KHz with CTIA and OMTP support is a serious wired audio path.
• Best for battery life → Flecom iPhone 17. Up to 48 hours with the case, plus a 2-hour case recharge.
• Best for workouts and rain → Flecom iPhone 17. IPX7 waterproofing and a lightweight in-ear fit with three tip sizes.
• Best for calls and hands-free control → Flecom iPhone 17. Touch controls, Bluetooth 5.3 and active noise cancellation.
• Best for travel and portability → Flecom iPhone 17. No cables, a compact case, and an LED readout so you always know your charge.
• Best for a single small purchase you keep forever → Stouchi 2-in-1. No battery to degrade, no case to lose, lifetime technical support.
If I had to pick one, I would buy the Stouchi 2-in-1. In my opinion it is the smarter accessory for most people who already own a decent pair of wired headphones, because it removes the daily annoyance of choosing between charging and listening, and it does so with a Hi-Res DAC and a 30W charging path. There is no battery to wear out and nothing to recharge. That said, if you want freedom from cables, the Flecom iPhone 17 is the better fit — its 48-hour case battery, LED display and IPX7 rating make it a genuinely practical wireless option. Buy Stouchi for wires, Flecom for wireless. Check the current price on Amazon before you commit, since both are budget accessories and the gap may surprise you.
FAQ
They are listed for iPhone 17 Pro Max, 17 Pro, iPhone Air, 16 and 15 series, plus Galaxy S26, S25 and A-series models and Pixel phones. Any Bluetooth-enabled device can pair with them.
The Flecom earbuds, clearly. They offer up to 48 hours with the charging case and a 2-hour case recharge. The Stouchi adapter has no battery at all — it draws power from your phone's charger.
No. They connect over Bluetooth and do not pass charging through to your phone. If charging and listening at the same time is your priority, the Stouchi 2-in-1 is the one that does that job.
