    The energizer looks very small. Is this a portable unit with an internal battery?
    Tom T on Oct 21, 2018
    BEST ANSWER: This information is included in one of the description images: "The Monolith Electrostatic Headphones feature a light weight and portable amplifier... The headphone amplifier is fitted with a standard USB charging port. Not only can it be powered by any USB power source, the built-in rechargeable lithium battery allows it to function for up to 5 hours on a single charge. Unlike most battery powered devices, it can be used while the battery is charging."
    tl;dr - Yes, it's a rechargeable lithium battery that lasts 5 hours.
    Will it work with other electrostatic energizers/amplifiers?

    In what capitalist dystopia is a pair of headphones worth more than a mid tier graphics card?
    kane v on Nov 6, 2018
    BEST ANSWER: What is a video game? I just buy a graphics card that can drive a 4K monitor at 60Hz using dedicated GDDR memory and maybe some compute cores to speed up video rendering. AMD's RX470/480/570/580 and nVidia's GTX 1030 and 1050 are more than sufficient. A good pair of headphone, especially electrostatics, make me drool! I am done paying for high end stuff, but this mid-tier stuff has gotten so good over the past few years that I am more than happy to vote with my wallet.
    With the open back, can these be worn on an airplane without disturbing your neighbor in the seat next to you?

    Excellent Sound....Build leaves a Lot to be Desired
    I've spent 24 hours with these and I am definitely impressed. The sound is extremely accurate as mids and highs are excellent. It rivals Shure's KSE1200 in terms of accuracy but it lacks the isolation obviously with it being an open-back headphone. However it has an advantage of being much more spacious allowing the soundstage to open up and that is where these really shine. Their accuracy and "airiness" are both excellent and it allows for a very authentic sound.

    These headphones come with a portable charger and it is very basic in it's aesthetic and function. There is a power switch and 3 ports and that is it. On one end there is a 5-pin XLR port for the headphones to plug into. And on the opposite side is the mini usb port (for charging) and 3.5mm port for audio-in. Overall the charger lasts just under 6 hours (I got 5 hours and 43 minutes out of the box) and recharge time was just under 3 hours. The amp itself is nicely made and is light without feeling cheap.

    The headphones themselves are another story. They sound amazing, but they feel cheap. They feel like a pair of generic headphones you would buy in mexico...in a rundown market. There is no premium materials and there is nothing spectacular in their design. They are as basic as it gets in terms of headphone design and they just don't feel great. They creak whenever you move your head and honestly durability is a concern for me.

    Comfort is a major plus however. The leather feels nice and the padding is great. Also since they're constructed from "non-premium" materials the headphones are extremely light and can be worn for hours at a time without any pressure spots forming. With most headphones comfort is an issue for me (audeze, grado, etc), these presented zero issues and they are great in that respect.

    Overall I would recommend these as I think the price tag is great and I think the sound is spectacular. The only thing that gives me pause is the build quality...it does worry me and honestly these headphones should carry a 3 year warranty at this price tag, not just a year.
