Headphones Aiwa HST-250BT/TN — Wired & Wireless Bluetooth Head-band, Circumaural, 20–20000 Hz, 1.5 m cable, Black

Aiwa HST-250BT/TN are circumaural head-band headphones offering both wired and Bluetooth wireless connectivity for calls and music. They use 40 mm drivers and cover a 20–20,000 Hz frequency range, with Bluetooth 5.0 for wireless transmission up to approximately 10 m. The design includes soft leatherette earpads and a cushioned headband, an ergonomic folding and swivel system for travel, a built-in microphone for hands-free calls, and a 1.5 m auxiliary cable for wired use. Charging is via Micro-USB and the built-in rechargeable lithium polymer battery provides up to about 12 hours of music playback and around 13 hours of talk time.

Advantages

The Aiwa HST-250BT/TN combines wired and wireless modes so you can switch between Bluetooth streaming and a direct 3.5 mm connection without additional adapters. The circumaural over-ear shape and plush leatherette pads provide practical passive acoustic isolation for clearer listening in noisy environments. Bluetooth 5.0 ensures broad device compatibility and stable connections, while the integrated microphone supports hands-free phone use. Additional features such as a microSD slot for standalone MP3 playback and a compact folding mechanism add convenience for commuting and travel.

Suitable for

• Everyday music listening at home or on the go
• Mobile and remote work calls, online meetings and voice chats
• Commuting and travel due to folding and swivel headband
• Use with phones, tablets and laptops via Bluetooth or 3.5 mm cable
• Standalone MP3 playback from a microSD/TF card

When it may not be suitable

These headphones provide passive noise isolation but are not equipped with active noise cancellation, so they may be less effective in very loud environments such as aircraft cabins or heavy industrial settings. Users who require studio-grade reference accuracy may find the sound tuned for general listening with enhanced bass rather than strictly flat, clinical response.

How to use

For wireless use, fully charge the headphones via the supplied Micro-USB cable, power them on and enable Bluetooth on your source device. Pair the devices following the voice-prompt guidance; once connected you can stream audio and use the built-in microphone for calls. For wired use, connect the included 1.5 m 3.5 mm cable between the headphone jack and the audio source; wired mode may be used while the battery is depleted. To play files directly from a microSD/TF card, insert a compatible card into the slot and use the onboard controls to navigate tracks. Fold and swivel the earcups for compact storage when travelling.

What to consider before purchase

• These are passive isolation headphones, not active noise cancelling (ANC).
• Battery capacity and quoted playback times are approximate and depend on volume and usage patterns.
• Micro-USB charging is used rather than newer USB-C; check charger compatibility.
• If you need reference-studio neutrality, consider headphones specified for flat response.
• MicroSD slot supports standalone MP3 playback; verify card capacity and format compatibility.

Usage recommendations

To maximise battery life, charge the headphones fully before extended use and reduce volume when possible. For clearer calls, ensure the microphone area is unobstructed and position the headset so the microphone points toward your mouth. Store the headset in the included pouch and fold the earcups to protect the leatherette pads during transport.
