Koss PLUGR Red Earbuds 10-20000Hz 16Ω 112dB 0.05kg

Koss PLUGR Red Earbuds

The Koss PLUGR Red Earbuds are new in-ear headphones with memory foam cushions that expand for a custom fit. They deliver noise isolation with a frequency response of 10 to 20000Hz, 16 Ohms impedance and 112dB sensitivity. The straight, dual-entry cord is four feet long and the unit weighs 0.05kg.

Who these suit and who should look elsewhere

They suit listeners who want portable, wired earbuds with deep bass and treble clarity for on-the-go use. Buyers who need wireless connectivity, an inline microphone, active noise cancellation or a different colour should look elsewhere.

Deciding specification: 16 Ohm impedance

The 16 Ohm impedance means these earbuds are easily driven by smartphones, laptops and portable players without an external amplifier. If your source has a very high output impedance or you require a balanced connection, this model will not match those needs.
