KVIDIO Bluetooth Headphones Over Ear vs Panasonic RP-HT21 On-Ear Headphones

What reviewers say

Panasonic RP-HT21 On-Ear Headphones

  • 4.5 / 5329 ratings

Rated 4.5 out of 5 from 329 ratings, buyers treat the RP-HT21 as a cheap, light headphone that does the basics well. Most praise centers on comfort and value rather than sound quality.

What people mention
  • ComfortPraisedOwners say the 1.2 ounce weight and foam pads stay comfortable for hours.
  • ValuePraisedBuyers see it as a lot of headphone for a very low price.
  • BassPraisedThe XBS port gives more low end than buyers expect at this size.
  • Sound leakageCriticisedThe open-air design lets sound out and outside noise in.

Questions and answers

Which is better for travel?
The KVIDIO. It is wireless, folds up and runs up to 65 hours per charge, so you are not tied to a seat or a cable. The Panasonic is lighter but wired and open, so it leaks sound and picks up cabin noise.
Which is better for calls?
The KVIDIO, because it has a built-in microphone. The Panasonic RP-HT21 has no integrated mic, so you would need your phone or laptop mic.
Which lasts longer?
The Panasonic has no battery to wear out and a reinforced L-shaped plug, so it can keep working for years as a simple wired pair. The KVIDIO's battery and electronics are the parts that age, though 65 hours per charge means fewer cycles.
Is the KVIDIO worth stepping up to over the Panasonic?
Yes if you want wireless, a mic and noise isolation. No if you only need a light wired pair for a desk or a backup and do not want to manage charging.
Which is better for gaming?
The Panasonic, because it is wired with no Bluetooth latency. The KVIDIO's roughly 250 ms wireless delay is noticeable in games and video unless you use the 3.5 mm cable.
Which is more comfortable for long wear?
The Panasonic is far lighter at 1.2 oz with foam pads, which suits long sessions. The KVIDIO's over-ear cups seal better and spread weight, but at 7 oz it is heavier.
