Popular questions
If the included cable gets damaged, can it be replaced?
Superlux HD668B headphones feature a detachable cable with a 3.5 mm mini-jack connection, allowing the cable to be replaced without repairing the headphones themselves. The package includes a 3 m main cable and an additional 1 m cable, which is convenient for stationary use.Source:Specifications
Can they be taken on the subway or bus?
The Superlux HD668B are better suited to a quiet room than to travel: surrounding noise will be clearly audible, and the music may disturb nearby passengers. For trips, it is better to choose closed-back headphones with higher isolation.Source:SpecificationsExpert reviewsUser Reviews
Will I need to use an equalizer with the Superlux HD668B?
An equalizer may come in handy if the high frequencies seem harsh. The review notes a pronounced boost in the 5–6 kHz range, and users also mention accentuated highs, especially at high volume.Source:General information
Are the Superlux HD668B suitable not only for audio work, but also for listening to music, gaming, and watching movies?
They are well suited for home use and quiet workplaces: detailed sound reproduction and a spacious soundstage enhance music, gaming, and movies. However, they are not the choice for fans of powerful, deep bass, as the low frequencies here are more controlled than accentuated.Source:Expert reviewsUser Reviews
Will the Superlux HD668B put pressure on your ears during prolonged listening?
The fit is highly individual: many owners praise the light weight of 222 g and the self-adjusting headband, but some complain about the strong initial clamping force. Head shape and sensitivity to ear pad pressure are especially important before extended use.Source:General information
Do I need a separate amplifier or DAC?
Superlux HD668B can be connected to a standard source, but the quality of the audio chain can affect the listening experience. The model has an impedance of 56 ohms and a sensitivity of 98 dB, while reviews vary: some owners recommend a good source, whereas others do not consider an expensive amplifier necessary.Source:Expert reviewsUser Reviews
