Home/iPhone/Cables & Adapters/Lightning to 3.5mm Adapter (1-Pack)
This is a single Lightning to 3.5mm dongle for a Lightning iPhone, priced as cheaply as they come. On a working unit it does the job — music, calls, acceptable sound. The odds of getting a working unit the first time are the problem.

A single small white dongle with a Lightning plug and a 3.5mm socket. There is nothing to it, and the build quality draws blunt criticism in reviews.
Plug into the Lightning port, plug in headphones. Confirm iOS recognises it — some units do not pass the MFi handshake cleanly.
Sound quality, connection stability, mic support and build are the measures. On a working unit, music and calls both function and sound is acceptable. The problem is how many units are not working units — dead-on-arrival and early failure reports are common.
Works with:
Not compatible:
Low build quality, frequent early failure, no warranty. Disposable.
At $8.99 on Amazon (checked August 26, 2026) for one, it is not even cheaper than the two-pack version of essentially the same product.
The value case is weak: same low quality as the two-packs, but only one unit, so a dud leaves you stuck. For a dollar or two less per unit you can buy a two-pack and hedge; for a few dollars more you can buy a branded UGREEN adapter that works. We would call it a fair buy under about $6, and only if the two-pack is unavailable.

| Product | Best for | Key advantage | Main drawback | Price |
|---|---|---|---|---|
| Lightning to 3.5mm Adapter (1-Pack) (this adapter) | The cheapest single Lightning dongle | Low price | Low build quality; dead units common; no spare | $8.99 |
| Lightning to 3.5mm Adapter (2-Pack) | The same product, with a spare | Two for ~$9 — hedge against a dud | Same quality issues; calls often fail | $8.99 |
| UGREEN Lightning to 3.5mm Adapter | One Lightning adapter that actually works | MFi DAC, sturdier build, calls work | A few dollars more; still some static reports | $15.99 |
If you are going to buy an unbranded Lightning dongle at all, buy the two-pack so a dud does not leave you stuck. For reliability, the branded UGREEN adapter is the right call. Prices are Amazon figures from August 26, 2026.
This single-pack Lightning to 3.5mm adapter is a cheap dongle for a Lightning iPhone, and on a working unit it does the job — music, calls, acceptable sound.
The trouble is the odds. Build quality draws blunt criticism, dead-on-arrival and early-failure reports are common, and there is no brand or warranty. Buying a single unit means a dud leaves you with nothing. Its 2.7 score reflects that. If you must buy an unbranded one, get the two-pack for the same price so you have a spare; for reliability, the branded UGREEN adapter is worth the extra.

This is an unbranded, low-information listing. “N/A” means the value is not stated.
No. Those are USB-C. This is a Lightning adapter for iPhone 14 and earlier.
On a working unit, yes. But a common complaint is that units do not work at all.
No — it is about the same price. The two-pack is better value because it includes a spare.
No. There is no pass-through Lightning port.
No warranty is stated and there is no brand behind the listing.
The two-pack of the same product if you want cheap-with-a-spare, or the branded UGREEN adapter if you want one that reliably works.
