In a nutshell, ships within 24/48 hours basically means that your product will be shipped out or dispatched from our warehouse within 24/48 hours after placing the order.

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.

Works for Taking Calls

Need to take calls while enjoying your music?


These headphones have got you covered 📞! I've found that nothing's more frustrating than missing important calls because your headphones don't handle them well. These products come equipped with built-in microphones and seamless call functionality, ensuring you never miss an important conversation while immersed in your audio experience. Think of them as your personal communication assistant that switches effortlessly between entertainment and business.


These devices are specifically engineered to provide crystal-clear voice transmission during calls, featuring advanced noise-cancelling technology that helps eliminate background interference. The intuitive controls make it simple to answer calls, adjust volume, and return to music without reaching for your phone.


When you see "☎️ Works for Taking Calls" products, expect versatile audio solutions that excel at both music playback and communication, perfect for professionals and anyone who values seamless connectivity.

IPX Rating

I’ve found that IPX ratings are a bit like an umbrella — you don’t always need it, but when you do, you’re glad it’s there ☔. “IPX Rating” tells you how resistant a product is to water and sweat, making it a crucial factor for outdoor use or workouts.


Now, here’s what’s actually happening: IPX is a standard that ranges from basic sweat resistance (IPX4) to full waterproofing (IPX7 or IPX8). It means your earphones won’t die on you mid-run or if you're caught in a drizzle. Just remember, IPX ratings don’t cover dust or solid particles unless they have a second digit (like IP67). So, if you're near the beach or in the gym a lot, this is a badge to take seriously.


When you see '☔ IPX Rating' products, expect: sweat- and splash-resistant gear that won’t flinch in the rain, at the gym, or during your toughest workouts.

Tweak & Tune the Sound

Why settle for a fixed sound signature when you can shape your audio experience exactly to your preferences 🎛️?


I love products that put you in the driver's seat of your audio journey. These specialised headphones come equipped with sophisticated, customisable tuning capabilities that let you adjust every aspect of the frequency spectrum. Think of it like having a personal audio chef who can adjust the recipe to your exact taste - more bass for your workout playlist, clearer mids for podcasts, or sparkling highs for classical music.


The adjustable sound signature means you can fine-tune bass response, adjust midrange clarity, or enhance treble detail. Whether you prefer deep bass frequencies, crystal-clear midrange presence, or pristine high-frequency detail, these solutions put you in complete control of your sound 🎚️.


When you encounter "🔧 Tweak & Tune the Sound" products, expect complete sonic customisation that adapts perfectly to your unique listening preferences across different genres.

Why it Sounds Amazing

Balanced Armature Driver

Enjoy accurate and precise sound 🎯, because every nuance in your favourite music deserves to be heard with perfect clarity! I believe balanced armature drivers are like "precision instruments" that excel at reproducing intricate musical details. These incorporate tiny yet incredibly precise mechanisms that deliver audio reproduction with exceptional detail and accuracy. Think of them like Swiss watchmaking for audio - incredibly small, incredibly precise, and engineered for perfection in every detail.


The compact design and efficient operation allow them to excel at reproducing intricate musical passages with outstanding precision and control, revealing every subtle detail and gentle texture 🔬.


When you see "🔈 Balanced Armature Driver" products, expect microscopic detail retrieval that reveals every subtle musical nuance with exceptional precision and clarity.

Balanced Sound Signature

In my experience, a balanced sound signature is like a well-cooked meal—nothing overpowering, everything in harmony. If you’re someone who listens to a bit of everything—rock one day, jazz the next—this is the tuning I’d recommend. It doesn’t boost any part of the sound unnaturally, so what you hear is often how the artist intended it. 🎧


Here’s what’s actually happening: the headphones don’t favour bass, mids, or treble excessively. This results in a neutral, natural, and versatile sound that suits a wide variety of music genres. While it may not feel as “exciting” as some more coloured tunings, balanced headphones tend to offer the most accurate reproduction, making them a favourite among audiophiles and studio pros alike.

Ultra-Wide Sound Stage

Do you wish to bring the concert hall to your ears 🏛️?


I love describing ultra-wide soundstage as "audio magic" that creates a breathtaking three-dimensional environment around your head. These specialised headphones feature an exceptionally spacious soundstage that creates the illusion you're sitting in the sweet spot of a magnificent performance venue. Think of it like teleportation technology for your ears - suddenly you're not wearing headphones, you're sitting in Carnegie Hall with perfect acoustics.


The precise instrument placement and remarkable sense of space work together to transport you directly into the music, making you feel as though you're experiencing a live performance. This creates a listening experience that's grand, enveloping, and incredibly detailed 🎭.


When you encounter "😳 Ultra-Wide Soundstage" products, expect concert hall acoustics that make you forget you're wearing headphones through sheer spaciousness and realism.

Crisp Vocals & Instruments

Vocals and instruments sound so good, it's like a warm hug 🤗!


I believe that when vocals are reproduced correctly, they should feel like the artist is performing right there with you. These headphones demonstrate exceptional prowess in reproducing clear, articulate vocals and instruments, with each element rendered in stunning detail and separation. Think of it like having front-row seats to an intimate acoustic performance where every breath, every string resonance, every subtle inflection comes through perfectly.


The natural timbre and tonal accuracy create an engaging presentation where every nuance is preserved while maintaining fatigue-free listening. Each word, note, and subtle inflection is reproduced with outstanding definition and emotional connection 🎤.


When you encounter "🍿 Crisp Vocals & Instruments" products, expect vocal excellence that brings you closer to the emotional heart of every performance.

Smooth & Sweet Treble

Seeking something that sounds smooth and devoid of harshness 🥰? I tend to describe these headphones as having "silk-like highs" that caress your ears rather than assault them. These products are meticulously designed to deliver high frequencies that are wonderfully gentle, offering a listening experience that's both sophisticated and delightful. Think of it like the difference between premium chocolate and cheap candy - both are sweet, but one provides refined pleasure while the other can be overwhelming.


The carefully tuned treble presentation ensures musical details come through with remarkable clarity while maintaining natural, fatigue-free character. The refined high-frequency presentation maintains excellent detail and air while avoiding any hint of harshness or stridency ✨.


When you see "🍦 Smooth & Sweet Treble" products, expect refined high frequencies that deliver crisp detail with a touch of sweetness and sophistication.

Layered and Nuanced Sound

Imagine sitting in the second row of a grand music hall 🎼, where each instrument's placement creates a vivid sonic landscape before you. I believe these headphones recreate that precise spatial positioning, allowing you to distinctly perceive where each instrument would be on an imaginary stage. Think of it like watching an orchestra conductor - you can follow each section independently while appreciating how they work together in perfect harmony. The layered presentation ensures every element occupies its own distinct space while contributing to the whole.


This audio equipment creates a detailed listening experience where musical notes, overtones, and reverberations shine through clearly, keeping complex passages distinct and well-separated. The tuning excels at revealing subtle interplay between instruments and the natural ambiance of recording spaces 🎯.


When you see "🍰 Layered and Nuanced Sound" products, expect intricate soundscapes that reveal the depth, complexity, and artistry in your favorite music with exceptional clarity.

Perfect to Layback & Relax

In my experience, a laid-back sound is like sinking into your favorite armchair after a long day. It doesn’t push details in your face or try to overwhelm you with energy. Instead, it gives your music room to breathe and unfold naturally. Think of it like sipping a glass of smooth whisky—there’s warmth, body, and ease. These headphones or IEMs are ideal for those who want to unwind and soak in a mellow vibe, whether it's a jazz trio or acoustic singer-songwriter set. 🎧


Now, what’s actually happening here is a tuning that gently rolls off the treble and offers a warm, full low-end. The midrange stays intimate, while bass adds comfort without punch, and highs avoid fatigue, making long sessions a pleasure. You won’t get maximum detail or separation—but that’s the point. It’s not about dissecting the mix—it’s about relaxing into it. For bedtime listening or just zoning out, this is your sonic hammock. 😌

I think that Astell & Kern did a fantastic job with the UW100MKII: they sound great and offer the right amount of functionality, prioritising sound quality over gimmicky features.
The default EQ mode was our go-to for most genres, preserving high-frequency clarity while maintaining enough low-end oomph.
The detail and ultimate fidelity of the playback is one of the best I’ve ever heard from a True Wireless earphone. The resolving power of the design really lets the listener peer into the music.
The transition from the upper midrange into the treble is rather seamless with very good clarity and detail. Percussion has excellent snap.

Hi there!
Thank you so much for your feedback! We're glad to hear that you're enjoying the AK UW100MKII. Happy listening!

Himanshu Sheth (Pune)
Superb neutral signature. Wide soundstage. Vivid sound detailing.

With most reviewers mentioning that the earpieces fall out of the ear, and the in-ear detection is unreliable coupled with a reviewer on Headphone Zone mentioning that open box items are not as good as brand new, set off doubts in my mind about my openbox purchase.

Thankfully parcel contained all the original box packing, all eartips, literature etc except for the sealing tape. Whew. So much for the openbox scare.

My ear is medium sized and usually the eartips that come fitted as standard work superbly.

With the UW100, they just fell out. My heart sank. I should have listened to all the reviews. Fitted a size larger with the same result. I had bought the open box to minimise my risk and here it was almost coming true as per my worst fears. Fitted the largest eartips, they just about held in place. That was close.

The in-ear detection began to act funny like the other reviewers have mentioned. Oh boy.
Is this why this set is here in the open box sale?

The in-ear sensor is on the inside surface next to the LED. If that comes within 2mm of the cartilage part of the ear, it detects the "ear" perfectly. If we position the earbuds slightly rotated, which is possible with this design, no part of the ear activates the sensor. But align the earbuds with the primary mic and the "A" logo vertically facing forward, everything starts working as it should.

Don't need to switch off "In-Ear detection" which is the backup option in case you aren't able to get it to work. Glad mine works flawlessly.

I come from a DT770 Pro and AKG361BT in conjunction with iBassoDC05 and Jabra Elite 65t (mediocre) Audio Tecnica ATH SQ1TW TWS as reference.

The details on the UW100MKII is on the lines though not equivalent, to that you hear on the DT770 and the AKG361.

The soundstage is wide and instrument separation is superb. Detailing out of such small earbuds is nothing short of spectacular.

On "Another Day in Paradise", the starting low frequency tones before the drums kick in can be distinctly identified as two different sources.

On Santana's "Bella" many peripheral percussion instruments can be heard discreetly and enjoyed.

On Bass Heavy tracks like "Money For Nothing", each individual snare drum strike is heard separately instead of as one continuous cacophony.

George Michael's voice on Careless Whispers doesn't sound sibilant like on other headphones

The saxophone on Candy Dulfer's "Lily Was Here" sounds sweeter than the other TWS.

Jeff Beck sounds delicate and smooth.

Male and female vocals are smooth and enjoyable.

The single Knowles driver is awesome as is the DAC and amp chip.

The Audio Tecnica ATH SQ1TW is an enjoyable warm sound signature whereas the AK UW100MKII is a purist flat signature which can be tweaked via equaliser to give you the AT type warm sound as well. The app has a few preset plus customisable equaliser setting.

Bass heads may need a bit of tweaking or looking elsewhere.

Hope I have cleared a few doubts in the minds of fence sitters.

All in all, a highly recommended TWS for Audiopliles

Thank you for your detailed and insightful review!

Astell&Kern - AK UW100MKII a Good Ear Bud

Every thing is nice but maximum ear volume is like normal even 100% setting. One other thing is lac of codec. I purchased it for Netflix 4K movies which have very high quality of audio but this one is helpless. You can suggest me proper device for my purpose.
