Description
Until now, audiophiles had to choose between the immersive experience of open-backs or the isolation of closed-backs. Now, get the best of both worlds with the Sennheiser HD 820. It retains the privacy of a closed-back while reproducing a wide and natural sound field.
Put a Ring on It!
A 56mm ring radiator uses the driver’s air displacement without losing the rigidity that impacts rest and response times favourably. The inner and outer edges of the rings are secured to the driver. The voice coil vibrates the diaphragm, connected to the V-shaped groove found near the centre of the ring. With this combination and a unique driver angle, you can easily locate vocals and instruments in their environment for the sound that transports you to the heart of a recording.
Beautiful – in Looks & Sound
On the outer plane of each ring are precision concave glass reflectors that prevent the redirected sound waves from creating resonance and distortion. These reflect the energy created by the driver to a specially tuned absorber system, allowing the waves to mimic the behaviour exhibited in open-air models such as the HD 800 S. While also a striking visual feature, the technical execution of the glass reflector yields a soundstage never before experienced in a sealed headphone.
Engineered to Perfection
The magic of the Sennheiser HD 820 can be felt via thorough attention to detail. Each driver is engineered and rigorously tested to give you a spectacular performance right outside the box. Each model includes the frequency response plot unique to that set’s serial number. The vibration-damping chassis and inert headband insert provide complete stability while the luxurious earpads form a satisfying seal for perfect comfort and noise isolation.
Connections that Matter
Your preferred headphone should be versatile – perfect to suit your ever-evolving set-up. The HD 820 comes with 3 meters (9.8 feet) cables with a variety of terminations. These include the audiophile standard 6.3mm (¼-inch) and balanced 4.4mm connectors that can seamlessly connect to audio devices like headphone amplifiers, DACs, A/V receivers and more.

The amount you pay for this DAC is absolutely worth it. I'm using it with my PC, and I also have a Fiio KA13. It provides 32-bit 48000Hz audio output, and it's really good. I'm connecting it via a USB-C port and one extension cable (AGARO 3.5mm Aux Male to Female Extension Cable, Gold Plated). There’s no audio loss whatsoever.
The only minor issue is when you use it with a mobile device — the blue light can be a bit annoying. However, that's more of a personal preference. It also makes some noise with certain songs, but that's actually a known issue with the CS46L41 chip. There's no need to worry though; unless you've used a high-end DAC before, this will be more than enough for you.
Bass and clear vocals

Excellent sound quality

After searching internet found this dac which has multiple input options and support 165*2 watts passive speakers and 350 watt passive subwoofer for future extension, tested with all input modes, bluetooth input feels a bit of low quality as it only supports sbc and aac codecs only, however if you want to use mobile via wired, alternative option is to use audiocular d08 cs-pro usb-c to 3.5 mm and 3.5 mm to rca input (cable creation brand). Optical input mode supports PCM (loss less stereo output) and Digital compress audio multichannel only) these are specific to Sony X-80J 65 inches

Thanks a lot Pritam Ji for suggesting me to use a balanced cable with my Moondrop Aria IEMs and thanks a lot for ordering Moondrop Aria filters for me. The Audio Store goes out of the way to serve Indian audiophile community.
The way my IEMs sound with a balanced cable and Shanling UA2 Plus DAC & Amp are unprecedented!
I am grateful Pritam Ji. 🙏🏻

The empathetic support that I got (as a budding audiophile) from Pritam Ji at The Audio Store is unparalleled. I am grateful Pritam Ji. 🙏🏻

Just bought it and started using it with my IFI Zen Stack - feels awesome.
This was a natural pick for me, since I wanted to have a completely balanced setup for my HiFiMan Sundara.
Nothing much to add, if you want an optimal balanced setup without spending too much, then look no further.
Thanks AudioStore for being blazing fast with your delivery. I got it withing 48 hours of placing my order! Kudos.

For my HiFiMan Sundara, this is a nice quality 4.4 mm balanced cable. I am buying this for the second time, since the first one got destroyed by my kids.
If you are looking for a good quality 4.4 mm balanced cable, look no further.

This product is reached my expectation good purchase good audio signal transmission no noise at all.....thank you the audio store👍
Yes

I have used lots of TWS even high end of Samsung and Oppo worth 10K. But IEM sound signature is great! This is my second IEM. I had KZ-ZEX. It has dual driver with electrostatic. Compare with that MoonDrop Chu 2 is better clear and smooth sound signature even with single driver. I am using with Audiocular DAC cost 750. Just go with MoonDrop Chu 2 if you are music lover. Thanks.
Great packaging and quick delivery
