When musicians and producers in India start building their home studios, the Audio-Technica ATH-M50x is almost always the first major purchase. At around ₹13,000, it is universally recommended as the "industry standard" studio headphone. But eventually, as your ears develop and you start chasing better mixes, you inevitably hear about the "next level"—specifically, legendary audiophile and mixing headphones like the Sennheiser HD 650, which sit around the ₹27,000 mark in India.
Comparing these two might seem unfair at first glance. One costs double the other. But this comparison is actually one of the most important conversations you can have about studio gear. It isn't just a battle of price tags; it is a battle of design philosophies: closed-back versus open-back. Understanding the difference between what the ATH-M50x does and what the HD 650 does is the key to understanding why some mixes sound great in the studio but fall apart in the car. Let's break down exactly what your money buys in the Indian market when you make this massive jump.
The Design Philosophy: Tracking vs Mixing
To understand these headphones, you have to understand the physical difference in how they are built.
The Audio-Technica ATH-M50x is a "closed-back" headphone. The outside of the earcups is sealed solid plastic. When you wear them, they isolate you from the outside world, and crucially, they stop the sound of your music from leaking out into the room. This makes them tracking headphones. If you are standing in front of a microphone recording vocals, you need closed-back headphones so the microphone doesn't pick up the click track or the backing beat.
The Sennheiser HD 650 is an "open-back" headphone. The outside of the earcups features a metal grille that lets air and sound pass completely freely. When you wear them, you can hear your ceiling fan, the street traffic, and your own voice perfectly clearly. And anyone sitting next to you can hear exactly what you are listening to. Because the sound waves aren't bouncing around inside a sealed plastic cup, the audio sounds incredibly natural, wide, and uncompressed. This makes them mixing headphones.
ATH-M50x: The ₹13,000 Workhorse
The ATH-M50x is incredibly popular for a reason: it is virtually indestructible, folds up neatly for travel, and sounds instantly "fun" and exciting.
However, it is not a flat-response headphone. It has a distinct "V-shaped" EQ curve. The bass is heavily boosted, making kick drums and 808s sound massive, and the treble is sharp and aggressive, which highlights the crispness of cymbals and vocals. If you are producing electronic music or hip-hop, putting on the M50x makes you feel like you are standing in a club.
But that excitement comes with a massive drawback for mixing. Because the M50x exaggerates the bass, you might mix your track thinking the bass is perfect. Then, when you play it on a Bluetooth speaker, the bass completely disappears because the M50x was lying to you about how much low-end was actually there. Furthermore, because it is closed-back, the stereo image (the "width" of the sound) is very narrow. All the instruments feel like they are cramped directly inside your head.

The Sennheiser HD 650 has been a mixing legend since 2003. When you switch from the M50x to the HD 650, your first reaction might actually be disappointment. It doesn't sound "exciting." The bass doesn't punch you in the face, and the treble doesn't sparkle aggressively.
Instead, what you get is mid-range perfection. The human voice, acoustic guitars, and the fundamental frequencies of almost every instrument sit exactly where they are supposed to. The HD 650 is famous for its smooth, relaxed, and incredibly natural sound profile. Because it is open-back, the soundstage is wide and airy. You can actually hear the physical space between the instruments in a mix.
When you mix a song on the HD 650, it "translates." Because the headphones aren't exaggerating the bass or treble, if you make a mix sound good on them, it will generally sound good on your car stereo, your phone, and your TV.
However, there are two catches to the HD 650 in the Indian context:
- You cannot use them for recording. The sound leak will completely ruin your vocal takes. They are strictly for the mixing phase.
- They require an amplifier. The ATH-M50x is 38 ohms; you can plug it into your laptop or phone, and it gets deafeningly loud. The HD 650 is 300 ohms. If you plug it into a standard laptop jack, it will sound quiet, thin, and lifeless. You absolutely must own a dedicated audio interface or a headphone amplifier to drive them properly.
Head-to-Head Comparison
Sound Profile and EQ
The M50x is punchy, bass-heavy, and exciting, making it great for beat-making and casual listening but dangerous for clinical mixing. The HD 650 is famously flat, smooth, and mid-forward. It reveals the flaws in your mix rather than hiding them behind booming bass.
Comfort
The M50x has strong clamping force and synthetic leather ear pads that can get very hot and sweaty during a Mumbai summer. The HD 650 uses massive velour ear pads that surround your entire ear. Combined with the open-back ventilation, you can wear the HD 650 for eight hours straight without fatigue.
Durability and Build
Audio-Technica wins the durability war. The M50x is built like a tank and handles drops, spills, and rough backpack travel effortlessly. The HD 650 is entirely plastic with a metal grille; it feels premium but fragile. You keep the HD 650 safely on your desk.
Summary Comparison
Here is how the ₹13,000 closed-back champion compares to the ₹27,000 open-back legend in the Indian market.
| Feature | Audio-Technica ATH-M50x | Sennheiser HD 650 |
|---|---|---|
| Estimated Price (India) | ₹12,500 on Amazon - ₹13,500 | ₹24,000 on Amazon - ₹27,000 |
| Design Type | Closed-Back | Open-Back |
| Sound Profile | V-Shaped (Boosted bass/treble) | Flat, smooth, mid-forward |
| Impedance | 38 Ohms (No amp needed) | 300 Ohms (Requires interface/amp) |
| Best Use Case | Tracking vocals, DJing, beat-making | Critical mixing, mastering, audiophile listening |
The Final Verdict
If you are building your very first home studio in India and you only have the budget for one pair of headphones, you must buy the Audio-Technica ATH-M50x (or a similar closed-back like the Beyerdynamic DT 770 Pro). You need closed-back headphones to record vocals without mic bleed. They are the essential Swiss Army Knife of the studio world.
However, once your tracks are recorded and you are struggling to make your mixes sound professional across different speakers, that is when you graduate to the Sennheiser HD 650. It is not a replacement for the M50x; it is a companion. You track with the Audio-Technicas, and you mix with the Sennheisers. If you already own a good audio interface and want to stop guessing what your mixes actually sound like, the HD 650 is one of the smartest investments you can make for ₹27,000.
Frequently Asked Questions
Can I use the Sennheiser HD 650 for tracking vocals?
No. Because they are open-back, the sound of the backing track will bleed heavily out of the headphones and straight into your microphone, ruining your vocal recording.
Do I absolutely need a headphone amp for the HD 650?
At 300 ohms, they require significant power. While a laptop will produce sound from them, they will lack bass response, dynamics, and volume. A standard modern audio interface (like a Focusrite Scarlett or MOTU M2) can drive them adequately, though a dedicated headphone amp is ideal.
Is the ATH-M40x better for mixing than the ATH-M50x?
Many engineers actually prefer the cheaper ATH-M40x (around ₹9,000) for mixing over the M50x. The M40x has a flatter, less bass-heavy EQ curve, making it slightly more accurate, though the M50x remains more popular for tracking and beat-making due to its exciting sound.
Are open-back headphones bad for noisy environments?
Yes. The HD 650 provides zero isolation. If you have a ceiling fan running, traffic outside, or a noisy AC in your Mumbai apartment, you will hear all of it while wearing the headphones. You need a quiet room to use them properly.
Why are the Sennheiser HD 600 and HD 650 priced so similarly?
The HD 600 and HD 650 share the same physical design. The HD 600 is considered completely "neutral" and sometimes slightly bright, while the HD 650 is tuned to be slightly warmer and more relaxed in the treble. It comes down to personal preference, but both are legendary mixing tools.
