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.

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.

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

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.

Introducing A Fully Balanced Headphone Amplifier - The A70 Pro

A fully balanced headphone amplifier that elevates your listening experience is the Topping A70 Pro. This powerhouse offers unmatched audio performance thanks to its cutting-edge T'ang-ku-la Module, ultra-low noise input stage, and massive 17000mW x 2 output power. And with the added benefit of serving as a preamplifier, the A70 Pro adapts to your audio needs. With precise control, programmable settings, and a vibrant Aurora UI all-in-one stylish package, dive into the world of high-fidelity sound!

Features T'ang-ku-la Module With 3-Stage Feedback Circuit

The three-stage feedback circuit used by the T'ang-ku-la Module is new. The dynamic range increased to a record-breaking new level of 147dB by reducing noise and high-frequency distortion. Due to the technology's significant reduction in heat generation, reliability, the lifespan of electronic components, and thermal noise are all significantly improved. The A70 Pro's newly developed ultra-low noise input stage further enhanced the noise performance of balanced input and increased the input impedance to 20kΩ, improving compatibility with incoming devices. It also has a newly optimised new circuit architecture.

Redesigned Gain Architecture And Ground Loop Noise Switch

The gain architecture has been redesigned to reduce noise and distortion at high gain stages than the previous architecture. The A70 Pro has two level gain settings allowing you to pair high-sensitivity IEMs and high-impedance headphones. Ground loop noise may be experienced when using multiple devices simultaneously. A GND/LIFT switch is added to the A70 Pro. Change to LIFT to eliminate ground loop noise.

Relay Volume Control With Independent Volume Memory

The Topping A70 Pro uses relays and resistor networks to form an R2R volume control module, which provides precise volume control, long service life, and will not deviate even at low volume. The A70 Pro can memorise eight sets of volumes separately and automatically revert to the last used volume the next time the output is selected. The eight groups are headphone amp + preamp output, earphone all output, preamp all output, only 6.35mm output, only 4.4mm output, XLR output, RCA output and XLR output. Press and hold the C1/C2 button on the remote control for 3 seconds to save the current status (Including input channels, output channels, volume levels, and all settings in the setup menu). After successfully saving, press C1/C2 to use the corresponding settings.

Doubles-Up As A Preamp With A 12V Trigger Interface & A Remote

The A70 Pro functions well as a preamp and a driver for headphones. With an RCA output impedance of only 50 and an XLR output impedance of only 100, it offers the same high performance as the headphone amp mode. Additionally, a variety of power amplifiers with a variety of input impedances can use it. A fully functional remote control also makes operation even simpler. The A70 Pro has a 12V Trigger input and output interface, which allows for passive and active activation of other devices, triggering them to turn on and off simultaneously.

Elegant New-Generation Aurora UI With Expandable Inputs

Three touch buttons and a full-colour screen on the A70 Pro let you adjust the playback information, FFT, and VU to your tastes. You can access more features by turning the volume knob. One set of balanced XLR and single-ended RCA inputs are available on the A70 Pro. However, the Ext90 input expansion gives you a total of two single-ended RCA inputs and four balanced XLR inputs.

A Perfect Match With Topping's D70 Pro Sabre DAC

The Topping A70 Pro and D70 Pro SABRE have identical design languages and can meet the needs of the vast majority of headphones and active speakers. The A70 Pro and D70 Pro SABRE can be switched on and off in conjunction via the 12V Trigger connector, allowing the A70 Pro to be synchronised with the D70 Pro SABRE for automatic or manual switching.

  • Premium Economy

    Sensible spending meets sophisticated quality in perfect harmony 💫.


    I tend to describe premium economy products as finding that sweet spot where exceptional value meets refined performance. Think of it like business class comfort at economy prices - you're getting significantly more than what you paid for. These headphones deliver a refined listening experience that rivals more expensive alternatives, making them an intelligent choice for discerning listeners who appreciate both value and excellence.


    This thoughtfully curated selection demonstrates our commitment to bringing you outstanding sound quality and robust construction without requiring a significant financial investment. Each product has been meticulously evaluated to ensure it delivers performance characteristics typically associated with higher price brackets.


    When you see "💎 Premium Economy" products, expect refined audio experiences that bridge the gap between entry-level and high-end offerings, delivering impressive clarity and features at accessible price points.


  • Incredibly Popular

    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.

  • 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.


  • 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.

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.

EFFICIENT AND EFFECTIVE!

The Topping A70 pro is exactly what I thought it would be. A high-quality headphone amplifier with exceptional power capabilities. I have decided to pair it with the Topping DX7 Pro Plus, even though I am aware that the D70 Sabre DAC is considered the ideal match for the A70, as per Topping's claims. As a professional Mixing/Mastering Engineer, I am genuinely pleased with the pristine and transparent sound I am obtaining for my headphone setup with this combination. Thank you, Headphone Zone, for bringing these incredible pieces of equipment to India.

Nothing makes us happier than knowing you loved your purchase, we hope you had a comfortable shopping experience and thank you for the great review and ratings!
