ULTRASONE PANTHER: headphone amplifier with Hi-Res DAC that fits in every pocket


The PANTHER is the ideal companion for all headphones from our manufactory. High-end headphones like our Edition models can only play at their full potential with appropriately prepared material. This is where our PANTHER steps into the game: thanks to its high-quality D/A converter it offers the best sound in hi-res quality and provides sufficient amplification, too. With up to 20 hours of playback and compact dimensions, the PANTHER delivers high-end sound in pocket size, making it an audiophile upgrade for any source.


Marvelous sound on the go

Anyone who wants to enjoy high-quality sound on the go is faced with a problem: the converter units installed in mobile devices often become an annoying bottleneck for an audiophile sound experience. The PANTHER is a real help here: thanks to the AKM 4490 DAC chip, the PANTHER teases more quality out of any connected source. With up to 384 kHz and 32 bits of PCM resolution, the PANTHER is fully hi-res compatible and allows unadulterated and uncompressed sound in any situation. At the same time, the PANTHER purrs like a happy kitten in combination with its high-resolution DSD processing (up to DSD 256).


Compact, powerful and persistent

Despite its slim dimensions, the PANTHER not only accommodates a high-end DAC but also comes with a powerful headphone amplifier. From 16 Ω to 300 Ω: the PANTHER drives almost any headphones. Thanks to its powerful 3.000mAh battery it delivers audiophile amplification for many hours. By running the DAC,  it has enough endurance for up to 15 hours of continuous playback and for up to 20 hours via the integrated line-in input. With only 110g, the PANTHER never becomes a burden on the go.


Versatile in application

Smartphone, notebook, or tablet: the PANTHER works with a large number of source devices and thus offers a real sound benefit for various situations. For this purpose, adapter cables for Lightning, USB-C, Micro-USB, and USB-A connections are included in the box content. For maximum flexibility in headphones selection, the PANTHER features an unbalanced 3.5mm and a balanced 2.5mm headphone output as well as a gain switch.
