HyperX Cloud III Phone Connection & Box Contents

The HyperX Cloud III wired headset works with a phone, but only if your phone has a 3.5mm headphone jack or you use a USB-C to 3.5mm adapter. The box includes the headset, a detachable microphone, a 3.5mm audio cable, a USB-C to USB-A adapter, and a USB-C to 3.5mm adapter (in most regions). This guide explains exactly what is in the box and how to connect the headset to a smartphone, including common pitfalls and troubleshooting.

What’s in the Box

HyperX ships the Cloud III (wired version) with a consistent set of accessories, though regional variations exist. The standard contents are:

  • HyperX Cloud III headset (with attached 3.5mm cable)
  • Detachable noise-cancelling microphone (with pop filter)
  • 3.5mm audio cable (4-pole, TRRS) – this is the main cable that connects to the headset
  • USB-C to USB-A adapter – for connecting the headset to a PC or console via USB
  • USB-C to 3.5mm adapter – for phones or devices with only a USB-C port
  • Quick start guide and warranty information

Note: The USB-C to 3.5mm adapter is included in most retail packages, but some budget or bundled versions may omit it. Always check the specific listing or box label if you are buying used or refurbished.

How to Connect to an Android Phone

Connecting the Cloud III to an Android phone depends on the phone’s ports:

  1. If your phone has a 3.5mm jack: Plug the headset’s attached 3.5mm cable directly into the phone’s headphone jack. The microphone will work for calls, and audio will play normally.
  2. If your phone only has USB-C: Use the included USB-C to 3.5mm adapter. Plug the headset’s 3.5mm cable into the adapter, then plug the adapter into the phone. The headset should be recognized as an audio device immediately.
  3. If your phone has a Lightning port (older iPhone): You will need a Lightning to 3.5mm adapter (Apple’s official one or a certified third-party). The USB-C adapter in the box will not fit.

No additional drivers or apps are required for wired use. The headset is plug-and-play.

How to Connect to an iPhone

Modern iPhones (since iPhone 7) do not have a 3.5mm jack. To use the Cloud III with an iPhone:

  • Use an Apple Lightning to 3.5mm Headphone Jack Adapter (sold separately).
  • Plug the headset’s 3.5mm cable into the adapter, then into the iPhone.
  • The microphone works for calls and voice memos, but some apps (like certain games) may not route the mic correctly due to iOS limitations – this is a known iOS behavior, not a headset fault.

Note: The USB-C to 3.5mm adapter included with the Cloud III will not work with Lightning iPhones. For iPhone 15 and later, which use USB-C, you can use the included adapter directly.

Common Connection Problems and Fixes

If you plug in the headset and hear nothing, try these steps in order:

  1. Check the cable seating: The 3.5mm cable attaches to the headset via a locking mechanism? Actually, it is a standard 3.5mm plug – push it in firmly until you feel a click. Sometimes it looks connected but isn’t fully seated.
  2. Try a different source: Test the headset on a PC or another phone to rule out a dead headset or cable.
  3. Check phone volume: Ensure media volume is not muted and that the phone is not in “Do Not Disturb� mode.
  4. Use the USB-C adapter correctly: Some adapters are directional – try flipping the USB-C connector 180 degrees.
  5. Restart the phone: Occasionally, the audio routing gets stuck. A reboot clears it.

If the microphone doesn’t work on a phone call, check that the headset’s inline mute switch (if present) is not engaged. The Cloud III does not have an inline mute, but the detachable mic has a mute button on the boom – make sure it’s not toggled.

Comparing Wired vs. Wireless for Phone Use

The Cloud III also comes in a wireless version (Cloud III Wireless) that uses a 2.4GHz USB dongle. That version does not work with phones directly – the dongle is USB-A, and you would need an OTG adapter, and even then, it’s not guaranteed to work on all phones. The wired Cloud III is the better choice for phone use because:

  • No battery charging needed
  • Works with any phone that has a 3.5mm jack or USB-C with adapter
  • No latency issues
  • Lower cost

If you want wireless with a phone, you’d need a Bluetooth headset – the Cloud III does not support Bluetooth.

Audio Quality and Mic Performance on Phones

The Cloud III’s 53mm drivers deliver the same sound signature whether you plug into a PC or a phone. The microphone uses a 10mm electret condenser capsule – it will sound fine for phone calls, but it is not designed for professional podcasting. On some phones, the mic may sound quieter than expected because the phone’s audio codec expects a headset with a specific impedance – this is normal and can be adjusted by raising the in-call volume.

Frequently Asked Questions

Does the HyperX Cloud III work with a Samsung Galaxy phone?
Yes, if the Galaxy has a 3.5mm jack (most older models) or a USB-C port (newer models). Use the included USB-C to 3.5mm adapter for newer Galaxies. Samsung’s own USB-C to 3.5mm adapter also works.

Does the Cloud III come with a USB-C to 3.5mm adapter?
In most retail packages, yes. However, some region-specific bundles or reseller versions may not include it. If yours didn’t, you can buy a generic USB-C to 3.5mm adapter – they are widely available and cost a few dollars.

Can I use the Cloud III with a phone that has no headphone jack?
Yes, but you need an adapter. For Android with USB-C, use the included adapter. For iPhone with Lightning, you need an Apple Lightning to 3.5mm adapter (not included). For iPhone 15 or later with USB-C, the included adapter works.

Why does the microphone not work on my phone?
First, make sure the mic boom is fully inserted and the mute switch is off. Then check that the phone is using the headset mic – some phones have a setting for “headset� vs “phone� mic. If using an adapter, try a different one – some cheap adapters only pass audio, not mic.

Is the Cloud III compatible with Nintendo Switch?
Yes, the Switch has a 3.5mm jack in handheld mode. In docked mode, you need to connect to the TV’s headphone jack or use the USB-C adapter with the Switch’s USB-C port (works in docked mode).

Does the Cloud III work with a Google Pixel phone?
Yes. Pixel phones since Pixel 2 lack a headphone jack, but the included USB-C to 3.5mm adapter works perfectly. The mic also works for calls.
