What does "ships within 24/48 hours" mean?

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. It also indicates that the products are readily available at our warehouse and once we receive your order, we dispatch it out at the earliest either on the same day or the next working day depending on when you’ve placed your order.


What it does not mean:

A lot of our customers assume that it means their order will get delivered to them within 24/48 hours, but that’s not what it means. For an order to reach you, it can take anywhere up to 3-4 business days, depending on which part of India you are placing an order from.

Why it Sounds Amazing

Hybrid Drivers

Looking for a combo of rich and detailed sound 🎵?


I love describing hybrid drivers as getting "the best of both worlds" in one beautifully engineered package. These headphones feature sophisticated hybrid technology that masterfully combines different driver types to deliver extraordinary sonic experiences. Think of it like having a sports car with luxury comfort - you get the precision and speed of performance engineering combined with the richness and smoothness of premium materials.


By integrating multiple driver technologies, these devices achieve both rich, full-bodied sound and intricate detail reproduction. The result is a harmonious blend that captures subtle nuances and powerful dynamics, with each driver type contributing unique strengths to create a complete audio experience ⚖️.


When you see "🔈 Hybrid Drivers" products, expect expertly balanced performance that combines the best characteristics of different driver technologies for complete musical enjoyment.

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.

Thick Bass / Kickass Bass

When I say kickass bass, I’m talking about bass that slaps you right in the face—in the best way possible. It’s that visceral, chest-thumping low-end that makes you feel like you’re in the front row of a concert or a nightclub. If you’re into hip-hop, EDM, Bollywood beats, or anything with a deep groove, this is where the fun begins. 🔊💥


Here’s what’s going on technically: the low-frequency range is heavily emphasised, resulting in powerful sub-bass rumble and impactful mid-bass slam. This kind of tuning brings weight, warmth, and physicality to your music. The trade-off? It might mask some midrange detail or high-frequency sparkle—but for bassheads, the emotional payoff is more than worth it.

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.

Needs Amplification

I tend to say this when a headphone or DAC just doesn’t wake up unless it’s got some real juice behind it. Think of it like a sports car that needs the right kind of fuel—without enough power, it won’t go anywhere near top speed. Some gear, especially those with high impedance or low sensitivity, demands a dedicated amplifier to reach its full potential.


Here's the trade-off: these headphones or IEMs may sound underwhelming straight out of a phone or laptop, but when paired with proper gear, they transform dramatically. You get tighter bass, better control, and improved resolution.


If you’ve got a power-hungry planar or a studio-grade headphone, investing in a portable or desktop amp will unlock nuance, dynamics, and depth that you’re otherwise missing out on. ⚡

  • Warm & Smooth Sound Signature

    I tend to describe a warm & smooth sound signature as the audio equivalent of a hot cup of tea on a rainy day—comforting, rich, and easy to love. It's perfect for those who prefer relaxed, fatigue-free listening that doesn’t stab you with harsh highs or overly clinical detail. ☕🎶


    Technically, this means a slightly elevated bass and lower midrange, with tamed treble to prevent any sharpness. The result is a sound that's full-bodied and inviting, especially great for vocals, jazz, indie, and old-school rock. While it may not offer extreme precision, it excels in musicality and emotional warmth, making long sessions an absolute pleasure.

  • Thick Bass / Kickass Bass

    When I say kickass bass, I’m talking about bass that slaps you right in the face—in the best way possible. It’s that visceral, chest-thumping low-end that makes you feel like you’re in the front row of a concert or a nightclub.

  • 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.

  • Warm & Sparkly Sound Signature

    In my experience, Warm & Sparkly 🍯 is one of the most musical and emotionally satisfying tunings you’ll come across. I like to think of it like a vintage tube amp with fairy lights—you get that cozy, golden warmth in the lows and mids, but with enough shimmer up top to keep things lively 🍯. This tuning enhances the body of instruments and vocals, giving them a rich, full texture, while also adding just the right amount of sparkle in the treble to make details pop. It’s a go-to for those who want to feel both emotion and excitement in their music—perfect for soul, indie, acoustic, or even modern pop.


    Here’s what’s actually happening: the mid-bass and lower midrange are gently elevated, giving the sound a rounded, lush character, while the upper treble (around 8–10kHz) is also lifted slightly for brilliance and air. The result is a sound that feels smooth yet detailed, without harshness or fatigue. You’ll notice vocals have weight and emotion, cymbals have a natural sheen, and instruments feel both rich and crisp. The trade-off? If you're coming from a flat or analytical signature, this might feel a touch coloured—but that’s what makes it so engaging. It’s an inviting sound that flatters almost every genre 🎶.


    When you see '🍯 Warm & Sparkly' products, expect a lush, emotionally rich sound with just enough treble shine, ideal for listeners who love warmth without losing clarity.

  • 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 🎭.

  • 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.

The most remarkable in-ear monitors available at an exceptionally reasonable price.

These are by far the most comfortable in-ear monitors (IEMs) I have ever worn, outshining all the ones I have previously purchased.The IEMs have a comfortable fit that allows for extended listening without causing any discomfort. Cable is quite impressive with tangle-free.Upon initial auditory engagement with these In-Ear Monitors (IEMs), one's attention is immediately drawn to the mellifluous quality of the sub bass and bass frequencies. The auditory experience is notably pleasant and comforting to the listener. The other mid-range and treble can be heard with remarkable clarity, providing an equally comforting auditory experience. However, one potential drawback to consider is the overall lack of cohesiveness and crispiness.The sound stage is satisfactory, although it may not provide the desired sense of expansiveness.Although my experience in this field may be limited, after comparing this IEM with the Noble Audio Kublai Khan, Viking Ragnar, and SONY IER Z1R, I have noticed a lack of soul in the music range. Its like applying a soft Gaussian filter to the exquisite picture is akin to enhancing its visual appeal.It is strongly recommended for those individuals who are in need of calming auditory stimuli.In all ranges of frequencies, I find my overall experience to be delightfully soothing to my ears.I strongly suggest considering this IEM in this particular price range, as it offers an exceptional quality of listening experience.

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!

Bass plus music

Other iems: B2Dusk, Isn EST50, Symphonium meteor.
Source: RU6, mojo 2, RU7, Hiby RS6,FIio K7 and ibasso DX320 amp 11mk2s and amp12.
Disclosure: didn't buy it from Hpz but got them shipped by a friend from overseas.
For the review I found the best synergy with mojo 2 if I want to hear thumpy mid bass but sacrifice on soundstage and depth but gain musically.
And with
Ibasso Amp11 mk2s where I think the max potential of this iem came to light, for me. I don't know how chord electronics manages to do so much justice to bass delivery.
Anyways, the iem is capable of offering you a vivid, holographic soundstage, super controlled and still very thumpy mid bass. I test bass on 'The Plan - Tenet OST' and you can hear your ear drums feeling every bass attack in the first 15-20 seconds. The upper range is non-sibilant in all the genres I have tried and it never gets harsh. I am personally averse to piercing sibilance or high shimmer in my sound, so someone looking for a bright iem might like to skip it. It's not a neautralish running I would say. Balanced mids and highs with not too high sub bass or say extremely tastefully done sub bass and tremendous, thumpy, jackhammering mid bass that hits you like a wrecking ball. I still slap on like 6-8db more bass at around 100-125hz.
What it's not: it's not a relaxed presentation like an all BA symphonium meteor. Sure it's much more bassy, more technical and sort of better in most areas but meteor is simply non fatiguing where this iem has so much going on(in a very good way) that someone looking for a relaxed listen might find them a tad too engaging. I also happen to try UM mest mk2 and Solaris twilight for a few mins but I found both of their tuning to be relaxed compared to monarch. Twilight I liked much better than mk2. Personally, I would still like to keep meteor and mk2 both foe their distinctive abilities.
Also, the comfort on these(for me) was the best. Stock silicon tips fit like a glove on my ears and azla sednafit are a no brainer either ways. I can listen more on the azla . Silicon tips also don't hurt but just make their presence felt whereas azla is kinda non interfering.
Bass, soundstage, technicalities, imaging and instrument seperation. That is I would say are the hallmarks of this iem. I am sure you won't regret buying it for sure.

An outstanding IEM

Though i didnt buy the Monarch MK3 on headphonezone i feel i have to write this review. It really is fantastic and once you start listening on it you will not want to listen on your other IEMs for a while. The clarity,detail,bass and treble extension are spot on. Songs feel presented on wide soundstage and are presented beautifully. Great value for money. My endgame IEM.

Thanks for the great review! We're glad you love the ThieAudio Monarch MKIII!
