Frequently Asked Questions
What does "renewed" mean for these Sennheiser HD650 headphones?
"Renewed" indicates that the headphones have been inspected, tested, and restored to full working condition, offering a quality audio experience at a potentially lower price point than a new unit.
What is the significance of "open-back" design for these headphones?
The open-back design allows air to pass through the earcups, resulting in a more natural, spacious soundstage and reduced pressure build-up, but also means they offer minimal noise isolation.
What is the frequency response of the Sennheiser R-HD650 headphones?
These headphones offer an improved frequency response of 10 - 39,500 Hz (-10 dB), allowing for the reproduction of a very broad range of audible frequencies.
How do the hand-selected matched driver elements benefit the sound quality?
Hand-selected matched driver elements ensure that the left and right channels produce sound as identically as possible, contributing to precise imaging and a balanced stereo soundstage.
Are these headphones suitable for use with mobile phones or portable devices?
While they can connect, the Sennheiser R-HD650 are professional-grade headphones with high impedance often benefiting from a dedicated amplifier, making them less ideal for direct connection to most portable devices.
What is the purpose of the acoustic silk in the design?
The specially designed acoustic silk ensures precision damping over the entire frequency range, which helps to maintain consistent sound quality and contributes to the incredibly low 0.05% THD.
