• yobola Earbuds — biggest strength: True wireless Bluetooth earbuds with touch controls, a 10-meter range, IPX5 water resistance and a charging case that pushes total listening time to 25 hours.
• yobola Earbuds — biggest trade-off: Each charge gives you about 5 hours, so you will be reaching for the case regularly, and the design relies on sound isolation rather than active noise cancellation.
• Untvie Apple MFi Certified — biggest strength: An Apple MFi certified Lightning-to-3.5mm adapter that lets wired headphones work with a long list of Lightning iPhones, with no error pop-up and support for 48kHz / 24-bit lossless output.
• Untvie Apple MFi Certified — biggest trade-off: It is not a pair of headphones at all, it does not work over USB-C, and it explicitly does not support making calls.
• Who each pick is for: yobola Earbuds for anyone who wants cable-free listening on an iPhone (or any Bluetooth device); Untvie for anyone who already owns good wired headphones and refuses to give them up.
The yobola Earbuds are a minimalist, in-ear true wireless set built around convenience. They connect over Bluetooth with a range of up to 10 meters, so you can leave your phone on a bench or desk and keep listening. The drivers are dynamic, the frequency range spans 20-20000Hz, and the impedance sits at 32 ohm — a standard, easy-to-drive configuration that suits everyday music, podcasts and video. There is a built-in microphone with a clear-calls feature designed to reduce background noise, so taking a call mid-walk is part of the plan rather than an afterthought.
Battery life is where the design shows its priorities. You get roughly 5 hours per charge, and the carrying case adds enough capacity to reach about 25 hours in total. That is a genuinely useful number for commuters and gym-goers, but it also tells you these are not meant for marathon sessions without the case nearby. The earbuds are IPX5 water resistant, which covers sweat, rain and splashes — a sensible match for fitness use, which the product name leans into. Touch controls handle music, calls and volume, so there is no fumbling for buttons mid-run.
Who should buy them: someone who wants a simple, light, white in-ear wireless pair for workouts, walks, commuting and calls, and who values a compact case over audiophile tuning. Who should skip them: anyone who wants active noise cancellation, anyone who needs more than about 5 hours per single charge, and — importantly — anyone committed to wired headphones. These are Bluetooth only, with a USB charging connection and no headphone jack, so they will never plug into anything.
The Untvie adapter is a different category of product entirely, and it is worth being blunt about that. It is a 2-pack of Lightning-to-3.5mm aux adapters, finished in glossy white, weighing almost nothing. Its job is narrow and specific: take the Lightning port on an iPhone and turn it into a standard 3.5mm headphone jack so your existing wired earphones, headphones or car aux cable work again. The Apple MFi certification is the headline feature, and it matters — the adapter is designed to avoid the "not supported" error message that plagues cheap uncertified dongles, and it supports all iOS systems without extra software.
The spec sheet is more interesting than you would expect from a dongle. Inside is a 100% copper wire core for stable signal transmission, and the adapter supports up to 48kHz sample rate with 24-bit lossless output. If you own a decent pair of wired headphones, that is the point: the adapter is not supposed to be the bottleneck. Compatibility covers a long list of Lightning devices — iPhone 14/14 Plus/14 Pro/14 Pro Max, 13/13 Mini/13 Pro/13 Pro Max, 12 series, SE, 11/11 Pro, XS, XR, X, 8/8 Plus, 7/7 Plus, plus iPad and iPod touch. The package includes two adapters, so you can keep one with your daily carry and one in the car or at your desk.
Two limitations are stated plainly and you should take them seriously. First, it does not support USB-C ports — this is a Lightning accessory, so iPhone 15 and iPhone 16 owners using USB-C should not buy it. Second, it does not support making calls. This is a listening adapter for music, videos, movies and car or home audio, not a headset dongle with a mic passthrough.
Who should buy it: anyone with a Lightning iPhone who owns wired headphones they love, or who wants a reliable cable for the car, gym, office or travel. Who should skip it: USB-C iPhone owners, anyone who needs a wired headset for phone calls, and anyone who actually wants wireless earbuds.
• Best for wireless freedom → yobola Earbuds. Bluetooth with up to 10 meters of range, no cable tethering you to the phone.
• Best for wired headphone owners → Untvie Apple MFi Certified. It exists purely to keep your 3.5mm headphones alive on a Lightning iPhone.
• Best for workout and wet-weather use → yobola Earbuds. IPX5 water resistance is designed for sweat and splashes; the Untvie adapter is a small electronic dongle with no water-resistance claim.
• Best for total listening time per charge cycle → yobola Earbuds. About 5 hours per charge and roughly 25 hours with the case, versus a passive adapter that draws no battery of its own but requires the phone to power the audio chain.
• Best for audio quality with serious wired headphones → Untvie Apple MFi Certified. 48kHz / 24-bit lossless output and a copper core give a wired signal path the yobola's Bluetooth link cannot match.
• Best for taking calls → yobola Earbuds. Built-in mic and a clear-calls feature; the Untvie adapter explicitly does not support calls.
• Best for travel and shared setups → Untvie Apple MFi Certified. Two adapters in the box and a tiny footprint make it easy to leave one in the car and one in a bag.
• Best for anyone who hates carrying a case → Untvie Apple MFi Certified. Nothing to charge, nothing to pair, just plug in.
In my opinion, the right pick depends entirely on which side of the wire you are on, so I will be direct: if you want new wireless earbuds for an iPhone — for the gym, the commute, calls and everyday listening — I would buy the yobola Earbuds. The 25-hour case, touch controls, built-in mic and IPX5 rating make it a complete, self-contained solution. I would only steer you to the Untvie adapter if you already own wired headphones you refuse to retire, or you want a dependable Lightning-to-3.5mm cable for your car. It is an excellent accessory, but it is not a pair of headphones, and it will not make calls or work with USB-C iPhones.
how to use headphones for iphone
If you have Bluetooth headphones like the yobola Earbuds, pair them once through your iPhone's Bluetooth settings and they will reconnect automatically. If you have wired 3.5mm headphones and a Lightning iPhone, you need an adapter like the Untvie MFi certified dongle — plug it into the Lightning port, then plug your headphones into the adapter's 3.5mm jack.
how to use wired headphones for iphone
Wired 3.5mm headphones will not fit a Lightning iPhone directly. You connect them through a Lightning-to-3.5mm adapter — the Untvie unit is Apple MFi certified, so it is designed to work without an error pop-up and needs no extra software. Note that this particular adapter supports music, video and car audio but does not support making calls.
how to use wired headphones for iphone 15
You cannot use the Untvie adapter with an iPhone 15, because it is a Lightning accessory and the product states it does not support USB-C ports. For an iPhone 15 you would need a USB-C-to-3.5mm adapter instead. If you want to avoid adapters entirely on that phone, Bluetooth earbuds like the yobola model are the simpler route.
how to use wired headphones for iphone 16
Same answer as the iPhone 15: the iPhone 16 uses USB-C, and the Untvie Lightning adapter is not compatible with USB-C ports. You would need a USB-C audio adapter for wired headphones. If you would rather skip the dongle, a Bluetooth pair such as the yobola Earbuds connects wirelessly with no adapter involved.
