Geek Daily Deals Mar. 11, 2018: Massdrop x Sennheiser HD-58X Headphones; xDuoo Dac and Tube Amp Combo

Geek Daily Deals – upgrade your personal audio with these excellent deals; the Massdrop x Sennheiser headphones are crisp, clear, and detailed, and paired with the xDuoo DAC and slightly warm tube amp, will give you sonic joy.

Massdrop x Sennheiser HD 58X Jubilee Headphones:

The HD 58X Jubilee uses Sennheiser’s new 150-ohm drivers, which require less amplification than previous driver platforms while retaining the same magnet strength and driver size. This makes the new headphone easier to drive from sources like your mobile phone or digital audio player. The sound is clear, fast, dynamic, and lively: reminiscent in some ways of the HD 600 and in others of the HD 650. It places an emphasis on clean, extended bass, with a solid transient response and a smooth but clear upper midrange. Plus, with Sennheiser’s ongoing testing of all units in the series, you can be assured that the drivers hit the target frequency response and match in both left and right channels.

Because the HD 58X Jubilee’s open-back design won’t isolate you from outside noise or prevent sound from being heard by those nearby, it may be best-suited for quieter home and office environments. Like all headphones in this lineup, this new model can be disassembled by hand to its component parts, all of which can be replaced. Many of its parts are interchangeable with others in the series, and owners of the HD 58X Jubilee can benefit from the rich aftermarket and brain trust of modifications and gear matching—along with excellent long-term support from Sennheiser itself.

Thanks to the dual DAC chips, each channel is processed independently, resulting in lower crosstalk and noise for an overall cleaner performance.
