Use Wirelessly with Bluetooth

I tend to describe Bluetooth audio as wireless freedom with fewer strings attached — literally. When you see Use Wirelessly with Bluetooth, it means you can pair your headphones or IEMs with phones, laptops, or even TVs — all without reaching for a cable 🎶. It’s convenient, clutter-free, and great for everyday listening.


What’s happening behind the scenes is your gear is using Bluetooth codecs like SBC, AAC, LDAC, or aptX to compress and transmit your music wirelessly. Better codecs mean higher quality and lower latency. Of course, there’s a trade-off — Bluetooth won’t match the quality of wired gear, but today’s advancements have made the gap much smaller than before.


When you see '✂️ Use Wirelessly with Bluetooth' products, expect: tangle-free convenience and solid sound quality — great for commuting, workouts, or casual listening.


Battery Life

In my experience, battery life is one of those things that separates a good day from a frustrating one. It's like having a fuel gauge you can rely on — longer battery life means less charging and more uninterrupted music. Whether you're on a flight or just commuting across town, this is one spec you don’t want to overlook 🔋.


Technically, battery life refers to the hours your device can play music on a single charge. Today’s headphones and DACs can range from 4 to 40+ hours, depending on things like Bluetooth codec, volume, and active features like ANC. More battery life also means better travel and portability, though it might come at the cost of size or weight.


When you see '⏳ Battery Life' products, expect: longer listening sessions, fewer charging breaks, and stress-free portability for music that goes the distance.

Battery Capacity

I usually think of battery capacity like the size of your water tank — it determines how long the tap can run before drying up. In audio gear, higher capacity means more playtime, more power for your amp section, and better performance during high-demand usage 🧠. It’s especially important if your gear also powers powerful drivers or amps.


Measured in mAh (milliamp-hours), battery capacity helps you gauge how long your headphones, DAC, or amplifier will last between charges. Devices with higher capacity (like 3500mAh+) are ideal for extended use or when you’re away from a power source. Just know, larger capacity often means longer charging time and a slightly bulkier design.


When you see '🔋 Battery Capacity' products, expect: more power and longer playtimes — ideal for travel, long workdays, or heavy use without worrying about recharging.

Storage

I tend to think of this like carrying your entire music library in your pocket — no cloud, no streaming, no internet required 📀. When you see “Up to 2TB Storage,” you’re looking at gear that lets you store thousands of high-res tracks, albums, and even DSD files offline, ready to play anytime.


Now, here’s what’s actually happening: the device features a microSD card slot that supports cards up to 2TB — that’s a massive amount of local storage. This is especially valuable for portable audio players and offline listeners who prefer to carry their music in the highest quality formats without compromising space. No buffering, no compression — just direct access to your favourite files.


When you see '🐘 Upto 2 TB Storage' products, expect: vast offline music access — perfect for DAP lovers, lossless audio fans, or travel-heavy audiophiles.

Built like a Tank

Durability concerns? Rest assured 💪.


I tend to describe these products as audio equipment that's built to survive anything you can throw at them. These headphones incorporate high-grade metal components and reinforced design elements that ensure they can handle demanding conditions while maintaining structural integrity. Think of them as the military-grade vehicles of the audio world - over-engineered for reliability and built to last decades, not just years.


The metal construction provides exceptional strength and longevity while contributing to a premium feel that serious audio enthusiasts appreciate. Whether you're a professional who needs reliable daily-use equipment or someone who values long-term investment in audio gear 🏗️.


When you encounter "🪖 Built like a Tank" products, expect unmatched robustness and durability you can count on for years of intensive use.


Why it Sounds Amazing

DAC Chip

I like to say the DAC chip is the heart of any audio device — it’s the part that actually transforms digital files into music you can hear 🎧. Think of it like a chef decoding a recipe to create a delicious meal. The better the DAC chip, the more faithfully it translates your music. And in my experience, a great DAC can completely change how your headphones sound.


Now, here’s what’s actually happening: a Digital-to-Analog Converter (DAC) takes digital signals (your MP3s, FLACs, or streams) and converts them into an analog waveform your ears can enjoy. Different DAC chips — like those from ESS, AKM, or Cirrus Logic — offer their own sound signatures, levels of clarity, and noise performance. A good DAC ensures accurate timing, minimal distortion, and exceptional resolution.


When you see '⚙️ DAC Chip' products, expect: clean, detailed audio and better synergy with high-quality headphones — perfect for anyone upgrading from average sound to audiophile quality.

Power Output

I like to think of power output in audio gear like engine horsepower, it determines how much muscle your setup really has 💪. Whether you’re trying to drive a pair of power-hungry planar headphones or just want headroom for dynamic peaks, power output is the spec you want to check first.


Technically, it refers to the amount of electrical power (measured in mW or Watts) an amp or DAC/Amp combo can deliver to your headphones. More power means better control, improved dynamics, and the ability to handle demanding gear without distortion. But more isn’t always better, too much power with sensitive IEMs can introduce hiss or harshness.


When you see '🚀 Power Output' products, expect: strong driving capability, better dynamics, and optimal performance with headphones that need serious juice to shine.


Balanced Output

I often say balanced output is like using both hands to carry something heavy — it distributes power evenly and keeps things stable. In audio gear, balanced output helps reduce unwanted noise and interference, especially over longer cables. Think of it as a cleaner, more efficient way to transmit your music, ideal for anyone using high-end DACs, amps, or studio-grade headphones 🎧. You’ll typically find it on gear with XLR or 4.4mm connectors, and it's a must-have if you’re chasing that ultra-clean signal path.


Here’s what’s actually happening: a balanced output uses two separate signals, one inverted, so when interference is picked up along the cable, it gets cancelled out when the signals are recombined. The result? Cleaner audio, better dynamic range, and more power output — especially when paired with balanced headphones. The trade-off? You’ll need gear that supports balanced connections on both ends to really enjoy the benefits.


When you see '⚖️ Balanced Output' products, expect: ultra-low noise, more headroom, and better synergy with high-impedance headphones or sensitive IEMs — ideal for serious listening setups.

Can drive anything out of the box! With Precise and Rich Sound!

1 Week use Review!

Pairing these with Shure SE846 iem and Audeze LCD2 Closed Back..Great Punchy Bass! Clear Mids and Pristine Treble. Being a basshead and a veteran bass guitarist, got the Audeze’s for pumping the lows.

Brilliant 5th iteration of kann series with all the upgrades. Smooth user experience with crimson UI, making it look ultra premium with the layer of customised android compared to phone-like dull stock android on chi-fi devices. They want you to use this for what its made for and make you fall in love with this. Endgame device.

Sound signature can be altered to choice with headphones of varying signatures.

Few Cons unrelated to Sound:

1. AK Connect feature not polished..plays on my BOSE Soundtouch 30 via Airplay initially but the ak connect app hangs and asks to force quit randomly. Need to check on other speakers as it streams NAS library to earphones well, might be compatibility issue with bose.

2. After pressing home, when re-opening folders, it should remember the folder/artist/album etc. which was last open. Pls fix it ak.

3. EQ is somehow worsening the sound for me and presets are not present, adding preset option is there for sound engineer grade audiophiles with gain and frequency settings besides the regular bands.
Sound the best without eq, dar set to max, amp low with iem, mid-high with cans, crossfeed off.
True Sound!

Overwhelming product! Thanks to headphonezone for making all these devices available in india! 🇮🇳

P.S. Someone pls suggest good equaliser settings options for AK (Rock, Pop, EDM).

Thank you for such an in-depth and thoughtful review! Your insights are incredibly valuable and will surely help other audiophiles make informed decisions. And if you need any suggestions our guru's will be happy to help you.

Solid Sound and Built

Hai,this is my second AK,my first being a 10 yr old AK jr which is still in pristine condition.

A Big Chunk of Meat with Raw power an indestructible Macho Machine,

All that said the user interface as read in many reviews has been improved but still slacking in speed and finesse

Apple Music has some issues with the UI as i have faced an issue of not being able to play the downloaded songs and i have to delete and download again which is pretty annoying.

Then as its a portable player i can’t understand the need of a separate pre line out that too 4.4 and 3.5 outs,see for a desktop dap/dac fine but not in a portable one,actually they could have added a 6.3 mm instead

Then the player wont last more the 7 hrs on full charge when the amp is set on high along with the DAR switched on and honestly I didn’t get to any difference with the DAR.

Ops sorry if this sounds like a cons review rather than pros

Rest assured rather that those mentioned above THIS DAP IS A BEAST like a V8 ready to trample whatever you throw at them with that authority and surgical precision.

Once again thank you for bringing in these to our reach in India and Kudos to Team HPZ since none other than HPZ has such a strong line up of Personal Audio products with hardcore after sales support-Keep up the Great Job

Thank you

The best DAP around, Astell& Kern KANN Ultra

This DAP is far from impressive. Its simply the best. Functions, interphase, sound quality and most importantly, the levels of gain.

Hey there, thank you for the great review and ratings! So delighted that you are loving your purchase. Hope you had a comfortable shopping experience. Cheers!
