Should I buy it?

Sennheiser HD 620 S
CONSIDER
  • No real owner data yet β€” the verdict stays cautious
Great choice if these matter:
  • Long listening in a quiet room
  • Anyone who prefers a wired connection
  • Anyone who wants a closed design
Watch out for:
  • 150 ohm impedance may ask for more than a phone output gives
  • The specification page states no weight
Regret riskLOWlimited data
Main risks
  • 150 ohm impedance may ask for more than a phone output gives
  • The specification page states no weight
  • The specification page states no driver diameter
The risk level is computed from the release date, verified weaknesses and real owner reports. The confidence score only appears once real owner data exists.
This box relies only on verified specs, the release date and real owner reports. We do not predict prices.

Historical Product Info

Official launch details

Instead of tracking today's retail price, Kacbu keeps the product's official launch information as a reference.

Sennheiser's consumer headphones are sold by Sonova Consumer Hearing. The specification pages state no assembly country, so none is claimed here.

This is not the current retail price β€” it shows the product's historical, official launch information.
