THE NEXT STEP IN AUDIO DEFINITION
Remember Standard Definition video? It had a monopoly on bad visual quality. Video evolved, Standard gave way to HD, and 4k video made you hate the way HD looked. Video quality moved forward, but audio quality moved sideways. Lossy data compression kept bandwidths low, but everyone now listens to the audio equivalent to Standard Definition or worse.
MASTER QUALITY AUTHENTICATED
Imagine 4k video for your ears. Master Quality Authenticated (MQA) is an award-winning technology that unlocks every detail of the original master recording with the convenience of streaming audio. MP3 and similar streaming technologies deliver 10% of the original recording quality, but the HELM BOLT can stream and unfold MQA music at over 8 times the sampling rate of CD. Stream MQA content from Tidal, Nugs and Xiami. (For more info on how MQA works, go to mqa.co.uk.)
CRYSTAL CLEAR DETANGLING
How does MQA sound? Vocals have presence and clarity, drums and percussion are sharp and impactful, strings have tactile nuance, and mixes that are muddy with conventional streaming become detangled and multidimensional when heard in MQA.
The HELM BOLT is an amazing sounding High-End Digital Analog Converter for your high-res FLAC or WAV files, and it will improve audio quality while streaming Apple Music, Spotify, Amazon, and others. supporting playback of PCM files with sampling rates up to 384 kHz, or DSD files with sampling frequencies up to 5.6MHz.
The HELM BOLT is THX Certified for ultra-low harmonic, crosstalk, and crossover distortion. Unlike other mobile MQA-DAC designs, the HELM BOLT physically isolates the DAC from the USB connector for improved performance, and uses a three oscillator design for superior frequency lock with dramatic improvements over single oscillator DACs.
PLUG & PLAY
For Android*, iOS*, MacOS, and Windows 10. Featuring a USB-C input and a 3.5mm audio output to connect to your wired headphones or speaker system. Headphone output level automatically detects headphone impedance and sets level accordingly: (1V for < 150 ohms, 2V for >= 150 ohms.) A simple LED indicates MQA rendering or sample rate playback, Blue for idle or SD audio <= 48kHz, Red for HD audio > 48kHz, Magenta for MQA content.

It serves the purpose of being a portable USB DAC, and work with majority of apps (on android). It does become hot at times, especially if you're driving them at higher volumes. The bit-rate/sampling-rate LED indicator is ornamental, since Android by design, tries to keep a uniform bit-rate and sampling-rate. Very few apps like Neutron, support bit-rate based mode switching, however that is not a smooth experience.
On the physical side, the product image doesn't agree completely with the actual product, with the edge of the product being sharp compared to the rounded corners on the product page. Not sure if that is a different version of the same product.
I was using ASUS AI noise cancelling USB adapter, and it had a tendency to roll off the higher frequencies. Compared to that, the sound separation is better with better frequency response.
Excellent sound quality and fidelity when paired with my Marantz PM-35 amplifier and Wharfdales diamond 9.1 bookshelf. Supports high quality audio streaming.
The Helm Bolt has been the best recommendation that has been made as real portability and pairs very well with the USB Audio Pro app. Strongly recommend it for anyone who is looking for quality on the go.
I never thought It's going to deliver fantastic sound and pair with beyerdynamic it's simply superb
Received in a couple of days post ordering- super quick. The DAC itself works flawlessly, I have connected using the iPad, laptop and phones. The sound quality improvement is distinct and substantial. Have tried with stored FLACS, online lossless streaming from Apple music and MQA format from nuggs. Worked brilliantly well all the time (and, the LED indicator changed colour 🙂).
The device will survive some rough handling and comes with a nifty pouch.
PS: if you are planning on using with a Windows based laptop, please do change the default sound output stream in settings to high-res.
I use this types of product first time. After 12days using I'm very much happy. I recommend this product for enhanced quality of sound.

The Performance of this Balanced Adapter is Excellent.
Excellent headset if any doubts dm me ig@satika_sunidhi
Does what it is supposed to. Please do not ask how it changes the sound, balanced output only helps you get more power from a DAC/AMP that supports it. The alternatives were much more expensive and I find this one to be perfect. It's better than the stock cable that comes with Edition XS. If you have a source that can make use of a balanced cable, by all means go ahead and purchase one. The headphones that this cable supports scale well with extra power so it's a worthwhile investment.
Using with 7hz salnotes, quality is good so far
good packaging and great product.
After reading reviews, I ordered the Azla Sedna Earfit Crystal Medium Small size. These ear tips are very unique and have an adhesiveness to them which makes them really fit inside the ear canal. The sound quality greatly improves due to the compactness of the fit. These are premium ear tips and should last long in my opinion. I think the medium size is perfect for people with normal size ear canals. Really good stuff.
The iems stands what it says. Has balanced audio for purist. If you like metal then these are one of the best under 2k. Although I didn't like the mic it is not sensitive enough doesn't captures voice effectively.
You will love the sound, a superb pair of headphone to begin your IEM journey
Go for it blindly !!
It amplifies the music and also clarity if you are using any IEM it will sound better. I would have recommended it wholeheartedly if it were made in India product.
Highly recommend this cables after using its 16 core version which was very prone to tearing and ultimately tore away. This cable feels way sturdier than its 16 core version. And also this one does not tangle at all and the ear hook size is great for small - medium sized ears.
The cp 100 plus' silicone material is very nice and feel comfortable and unfatigueing to use for a long period of time. They also provide a very good grip and hold my moondrop arias in proper place without slipping away due to ear wax after prolonged listening sessions. Highly recommended if you feel your current eartips are causing discomfort.
I bought these to connect my Beyerdynamic Amiron to the ifi Gryphon using the 4.4 balanced input . These cables are well made and flexible . Sound quality is more open and clear . Recommended.
The excellent service from the Audio store . Faster delivery , even for delay dispatch am had an call from the support team. Am very happy with the product and the service provided by the Audio store.
