Wired earphones HOCO M78 with 3.5 mm jack, black, wired in-ear headphones

HOCO M78 wired earphones are in-ear headphones with a standard 3.5 mm jack designed for wired connection to smartphones, tablets, laptops and portable music players. The compact black housing and silicone ear tips provide a low-profile fit for everyday use, while the wired design ensures simple plug-and-play operation without the need for batteries or pairing.

Advantages

These wired in-ear headphones deliver straightforward audio playback and call handling through a universal 3.5 mm connector. The design focuses on portability and ease of use: lightweight construction, tangle-manageable cable and silicone tips that help reduce outside noise passively. The absence of wireless components offers consistent connection and no latency or battery constraints.

Suitable for

• Listening to music on devices with a 3.5 mm headphone jack
• Making and receiving voice calls on phones with a headset jack
• Using with tablets, laptops and MP3 players that support wired audio output
• Portable use when a compact, no-charge solution is needed

When it may not be suitable

These earphones require a device with a 3.5 mm headphone jack and will not connect to devices that only support wireless audio or have USB-C/Lightning-only outputs without an adapter. They are designed for basic wired audio performance and may not meet expectations for audiophile-level detail, active noise cancellation or very high volume output.

Key specifications

• Connection type: wired 3.5 mm jack
• Form factor: in-ear (earbuds with silicone tips)
• Color: black
• Cable: fixed wired cable (length varies by manufacturer standard)
• Use: audio playback and voice calls

How to use

Insert the 3.5 mm plug into the headphone jack of your device. Place the silicone tips into your ears and adjust for a comfortable fit to improve passive noise isolation. Control playback and calls using the device’s controls; if an inline microphone or remote is present on the cable, use that for answering calls and controlling volume or tracks. After use, wind the cable loosely or use a small pouch to store the earphones to reduce tangling and extend cable life.

What to consider before purchase

• Ensure your device has a 3.5 mm headphone jack or obtain a compatible adapter
• Consider ear tip sizes and fit for comfort and passive noise isolation
• Expect basic wired audio performance rather than advanced hi‑fi or active noise cancellation

Usage recommendations

For clearer calls, position any inline microphone close to the mouth but avoid covering it. Choose the ear tip size that provides a snug seal to improve bass response and reduce external noise. Store the earphones in a pouch when not in use to protect the cable and connectors.
