Popular questions
Does the Sennheiser HD 620 S have Bluetooth and controls on the earcups?
No, this is a fully wired model without Bluetooth, touch controls, or a mobile app. It includes a 1.8 m cable with a 3.5 mm mini-jack and a 6.35 mm adapter, so playback control remains on the connected device.Source:SpecificationsExpert reviews
Do the Sennheiser HD 620 S require an amplifier?
A source with ample power headroom is recommended: the 150-ohm impedance may be demanding for a basic laptop or phone output. The headphones will work from a 3.5 mm jack, but a DAC with an amplifier will help bring out their full potential without a lack of volume.Source:SpecificationsExpert reviews
Are they suitable for travel on public transport?
The Sennheiser HD 620 S are better suited for home, a quiet office, or studying than for the subway or an airplane. The closed-back earcups muffle quiet household sounds and conversations, but loud noise comes through noticeably because there is no active noise cancellation.Source:Expert reviews
Is it worth getting the Sennheiser HD 620 S if you want powerful bass?
For those who love pronounced, impactful bass, this is not the most obvious choice. The low frequencies here are more refined and warm than massive, and at low volume, the bass may come across as restrained.Source:Expert reviews
Won’t they feel uncomfortable during prolonged listening?
Sennheiser HD 620 S have soft ear pads and a reinforced headband, but the fit may be snug. Reviews note noticeable clamping force, so if you are sensitive to pressure on your temples or wear glasses, it is better to try them on before purchasing.Source:Expert reviews
Is it worth upgrading from the HD 569?
The Sennheiser HD 620 S is worth considering as a step up if a more refined appearance, a firmer headband, and a less sharp midrange presentation are more important. At the same time, the difference in fit and bass depends on head shape and how tightly the ear pads seal.Source:Expert reviews
