Overview
A basic lightweight on-ear headphone with a 3.5mm plug, adjustable headband, and a 4-foot cord, built around a 32-ohm driver rated for deep bass response.
There is little to this listing beyond the core spec sheet, which fits a headphone built to be an inexpensive, no-frills option rather than one leaning on features. The 80Hz-18,000Hz frequency range and 91dB sensitivity are wide enough for general music and podcasts on a directly wired connection.
- 3.5mm wired connection, 4-foot cord
- 32-ohm driver impedance
- 80Hz-18,000Hz frequency response
- Adjustable padded headband
Who it's for
Suited to anyone who wants a cheap, wired, portable headphone for a phone, laptop, or MP3 player without worrying about battery life. Not the pick for anyone wanting wireless freedom, active noise cancellation, or a snug over-ear seal.
Strengths and trade-offs
Drawn from this product's published specifications.
- Lightweight and simple to wear for long stretches
- Works directly from any 3.5mm jack with no battery needed
- Adjustable headband for fit
- On-ear design does not isolate outside noise
- No inline microphone or remote
Performance notes
The 32-ohm impedance is low enough to drive from a phone or laptop headphone jack without needing a dedicated amplifier, and the stated frequency range covers the low end where the listing's bass claim would come from.
