Avantree Resolve -3.5mm is my pick for avantree headphones no sound concerns in an office: its wired AUX connection avoids Bluetooth pairing steps. Avantree DG45 is the runner-up if you want Bluetooth headphones on a compatible Windows PC.
avantree headphones no sound at a Glance
• Avantree SP850 — best for radio and casual audio at a desk; pick this if you want FM, Bluetooth streaming, and SD-card MP3 playback in one portable device.
• Avantree DG45 — best for adding Bluetooth to a Windows office PC; pick this if your computer runs a supported Windows version and you want to connect Bluetooth headphones.
• Avantree HF027 — best for listening from a distance at a desk or with a TV; pick this if you need wired earbuds with a long coiled cable and a 3.5mm audio output.
• Avantree Resolve -3.5mm — best for office listening while staying aware of nearby sounds; pick this if you want wired open-ear earbuds with inline controls and a 3.5mm jack.
The SP850 is a compact portable radio and speaker that also handles Bluetooth streaming and MP3 playback from a standard SD card. Its LED display, station scan and number keys are intended to make radio listening straightforward. You can save a station to one of the number keys, then return to it without scanning again.
For office use, it suits someone who wants a small, standalone way to listen to radio, news, or audio from a phone. The device can also be used with headphones, and its 3.5mm jack offers a wired listening option. Its rechargeable battery and small form make it easier to move between a desk and another listening spot than a fixed speaker would be.
The limitation is in the role it plays: this is primarily a compact radio and speaker, not a conventional pair of headphones. Its speaker is specified at 2 watts, and the product information describes it as intended for personal, close-range listening rather than filling a large room. If “headphones no sound” means you need audio directly at your ears, the SP850 only makes sense if you plan to connect headphones to it.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The DG45 is a small USB Bluetooth adapter for Windows computers. It adds Bluetooth capability for compatible devices, including Bluetooth headphones and speakers. If your office PC lacks Bluetooth, this can give you a way to connect wireless headphones without replacing the computer.
Compatibility is the key buying check. The DG45 is limited to Windows 11, 10, 8.1, and 8; it is not for macOS, ChromeOS, Linux, older Windows versions, TVs, or consoles. It connects Bluetooth devices, not Wi-Fi products or equipment that needs its own 2.4GHz USB receiver. That distinction matters because two devices can both be wireless without using the same technology.
The adapter can pair with up to seven Bluetooth devices, although only one Bluetooth audio device can be active at a time. A keyboard and mouse can be used alongside an audio device, which is useful at a desk, but it does not let you listen through two Bluetooth headsets simultaneously. Compatible headphone microphones can also be used for calls in apps such as Teams or Zoom.
I recommend the DG45 when the computer’s operating system and the headphones’ connection type both match. It does not solve every silent-headphone problem: it is not a headset, and it will not make a non-Bluetooth pair wireless. If your headphones already connect to the PC but produce no audio, the issue may be elsewhere in the setup.
The HF027 is a wired in-ear set for devices with a 3.5mm audio output. Its long coiled cable plus a separate extension cable gives more reach than a typical short wired earbud cord. That can help when a computer or TV is away from your chair, or when you want some room to move around an office without disconnecting.
Soft silicone ear tips sit inside the ears, and a collar clip helps keep the cable in place. It includes a microphone, but using that mic on a computer with separate headphone and microphone jacks requires an audio mic splitter. The earphones have no inline volume control, so you need to adjust listening level on the connected device.
This is a practical choice if you want a direct wired connection and have the right output jack. The long cable can reduce dependence on Bluetooth pairing or charging, but it also leaves you managing a cord. Check the source before choosing it: a TV with only optical or coaxial audio output will not connect directly, and a fixed-volume 3.5mm output may not offer usable volume adjustment. Other output types may need an appropriate adapter.
The Resolve is a wired open-ear pair that rests on the outside of the ears rather than fitting into the ear canals. An earhook holds each earpiece in place. For office use, that design is a good fit for someone who wants to hear calls or audio while remaining aware of conversation and other nearby sounds.
The set includes two ear sizes, with the intended fit based on ear length: Small-Medium for ears under 2.5 inches and Large for ears over 2.5 inches. That makes fit worth checking before buying, especially if the earbuds may be shared. The open-ear style avoids pressure inside the ear, but it also lets ambient sound in, so it is not the choice for blocking out a noisy workspace.
Inline controls handle volume, playback, track changes, calls, and voice-assistant activation. A built-in microphone supports hands-free calls. The 3.5mm plug works with compatible AUX audio jacks on devices such as some laptops, PCs, older phones, and tablets; it does not connect directly to Lightning or USB-C ports. The open-ear design also means lighter bass than conventional in-ear earbuds.
In my opinion, this is the strongest fit here for someone seeking headband headphones for office alternatives without wearing a headband. It is not a headband model, but the earhooks keep it positioned while leaving the ears open. If your priority is quiet isolation or heavier bass, the HF027’s in-ear design is a more suitable direction.
We compared the published specifications and features, focusing on connection type, device compatibility, listening style, and office use. The order is our independent editorial opinion; no brand paid for placement.
The Resolve is a good match if you want open-ear listening and a wired 3.5mm connection. For Bluetooth headphones on a supported Windows PC, consider the DG45 instead.
Check that the source device is set to the intended audio output and that its volume is turned up. Also confirm that the connection matches the product: the DG45 requires Bluetooth and a supported Windows system, while the wired models need a compatible 3.5mm audio output.
The data provided does not establish that any model is designed or sized specifically for children. The Resolve includes two ear sizes, but its size guidance is based on ear length, so check fit rather than assuming it will suit a particular age.
No waterproof rating is specified for these four products, so I would not choose one on the assumption that it is IPX7 rated. For a spill-prone workspace, look for a model with a clearly stated water-resistance rating.
My final recommendation for office listening is the Avantree Resolve -3.5mm if you want a wired, open-ear fit and your device has a 3.5mm AUX jack. Choose the DG45 instead when your goal is adding Bluetooth headphones to a compatible Windows PC.
