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.

Some things deserve all the attention ⭐!


I've found that when something becomes incredibly popular in the audio world, it's usually for very good reasons. This exceptional audio gear has earned widespread popularity by consistently delivering outstanding performance that resonates with listeners across diverse preferences and experiences. Think of it like that blockbuster movie that everyone loves - sometimes, universal appeal indicates genuine quality rather than just marketing hype.


The widespread acclaim isn't just about trend or marketing - it's a testament to genuine quality and performance that has been consistently demonstrated through real-world usage. This popularity has been earned through merit, delivering reliable satisfaction to countless users 📈.


When you encounter "🥇 Incredibly Popular" products, expect proven excellence validated by the collective experience of satisfied users who've made these their go-to choice.

For Audiophiles at Home

I’ve always loved the ritual of coming home, settling into my favourite chair, and firing up a dedicated setup. Gear labelled For Audiophiles at Home is made for those moments — when you can really sit back and appreciate music in its purest form 🛋️. These products tend to be more powerful, larger, and often require wall power — perfect for a stationary rig.


Here’s the trade-off: these setups often involve external DACs, amps, or full-size headphones, which means more space, more power, but also more immersive listening. They shine when used in quiet environments, where detail, depth, and dynamics can truly be appreciated.


When you see '🏠 For Audiophiles at Home' products, expect: exceptional fidelity, stronger output, and the kind of soundstage that makes you never want to leave your listening chair.

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.


Connect With Cable

In my experience, there’s still nothing like the dependability of a wired connection when it comes to audio 🎧. I love describing it as the direct flight of music — no delays, no turbulence. When a product says “Connect with Cable,” it means you’re getting the most reliable signal path, with zero wireless compression and minimal interference.


Here’s what’s actually happening: a physical cable transmits uncompressed analog or digital signals directly from your source to your gear. This results in lower latency, no signal drops, and consistently better sound — especially when paired with a good DAC or amp. It’s ideal for critical listening, gaming, and professional use. The trade-off? You’re tethered — but for a lot of audiophiles, that’s a small price to pay for sonic purity.


When you see '🔗 Connect With Cable' products, expect: pure, uninterrupted sound quality that lets your gear perform at its full potential — perfect for focused, high-fidelity listening.

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.

Decodes Upto

When I see "Decodes up to" listed in product specs, I think of it like a music translator that speaks more languages than you’ll ever need. It tells you how far a DAC or audio device can go in handling hi-res formats—think PCM, DSD, or MQA—and at what resolution. 🧠🎶


Technically, this refers to the maximum bit depth and sample rate a DAC can process—like 32-bit/768kHz PCM or DSD512. The higher these numbers, the more detailed and lifelike the audio can potentially sound. But remember, real-world improvements depend on the recording quality and your headphones, not just specs alone.

A True VFM all rounder product

First of all, a loud shout out for the buying and delivery process from HEADPHONEZONE. Salute. Fully satisfied.
Now, the product -
Pros -
- Compact, real compact
- build, strong, solid, confidence boosting
- User friendly and quite ergonomical and intuitive design interfaces (including the remote)
- option in sound tuning (equalizer) and filtering is a (very) good to have thing
- Quite clear, airy, controlled sound reproduction. Attack and fade out is very well controlled for this price range.
- There are clinical sharp edges of separation between instruments. Hence placing (imaging) is bang on in both width and depth of the staging. Quite impressive for the price.
Cons -
- I felt the sound, specially mid section is a bit lean in direct. For my ear, Tone is better suited than the SDB. Others may have different perspective. I wish, Tone option in eq has a little bit more warmth.
- a standard 3.5mm headphone socket
