The Audio-Technica ATH-M40x headphones are a popular set of closed-back studio monitor headphones known for their neutral sound reproduction and comfortable fit. As an upgrade from the previous ATH-M40 model, the ATH-M40x offers high-quality audio performance at an affordable price point.
In this detailed review, we will take an in-depth look at the ATH-M40x headphones, including their design, build quality, sound quality, comfort, accessories, and overall value. We’ll also summarize some of the key pros and cons of these headphones to help you determine if they are the right choice for your needs.
Key Features
- Extremely balanced and neutral sound signature
- Ideal for studio monitoring and critical listening
- Very affordable price for performance
- Removable cables for convenience
- Metal reinforced headband for durability
Overview and Specifications
The ATH-M40x headphones have a simple yet robust design optimized for studio use. Key specifications include:
- Driver: 40mm neodymium drivers
- Frequency Response: 15 - 24,000 Hz
- Impedance: 35 ohms
- Sensitivity: 98 dB/mW
- Max Input Power: 1,600 mW
- Weight: 240g (without cable)
- Cable: Detachable 3m coiled and 3m straight
- Connector: 3.5mm (1/8”) with 6.3mm (1/4”) screw-on adapter
With a frequency range spanning the full audible spectrum, the M40x aims to reproduce sound with accuracy and precision. The low 35 ohm impedance allows them to be driven even from portable devices, while the high sensitivity provides loud volumes even from weaker audio sources.
Build Quality and Design
The ATH-M40x has a robust build quality featuring metal reinforced headband and swiveling earcups. The earcups can rotate 90 degrees for easy one-ear monitoring, and can also fold inward for portability.
The headphones are primarily constructed from plastic, with faux leather padding on the headband and earcups. While mainly plastic, the matte texture and metallic accents give them a nice premium appearance.
Build quality feels solid overall, with smooth swiveling motion and clicks when rotating the earcups. The headband is adjustable with numbered marking for consistent sizing.
Comfort-wise, the clamping force is moderate and the earpads are relatively soft. However, some may find the oval earpads too small and can cause discomfort after prolonged use. Aftermarket earpads may help in this regard.
Sound Quality
As studio monitor headphones, the ATH-M40x aims for a balanced, neutral sound reproduction. The sonic profile is quite flat across the frequency range without emphasis on any particular frequencies.
The bass is accurate and punchy, with good extension down to 15Hz. However, bass heads may find it lacking in sub-bass rumble compared to more consumer/bass boosted headphones.
The mid-range is clear and transparent. Vocals sound natural without artificial boosts. Treble is also smooth without excessive sharpness or sibilance.
Soundstage has decent width for closed-back headphones. Imaging is good with the ability to pick out individual instruments cleanly. Overall detail retrieval is excellent, allowing you to hear nuances clearly.
For monitoring and critical listening, the ATH-M40x provides a honest representation of the source audio. The flat frequency response helps you mix and master audio precisely based on what is present in the actual recording.
Accessories
The ATH-M40x comes with a decent selection of accessories:
-
Carrying pouch - Provides basic protection during transport.
-
Coiled 3m cable - Allows flexibility during studio use.
-
Straight 3m cable - For casual listening on the go.
-
6.3mm adapter - Allows connections to pro audio gear.
-
Earcups: Spare set included.
While a hardshell case would be better for travel, the included accessories cover the basics fairly well. Replacement earcups are handy to have as earpad material can deteriorate over time.
Use Cases
- Audio mixing and mastering
- Podcast and voice recording
- Field recording and sampling
- DJ monitoring
- Music analysis and critical listening
User Feedback Analysis
Looking deeper into reviews and user impressions, here are some common themes that emerge:
Sound Quality
The neutral sound profile receives heavy praise, with most reviewers commenting on the clean and accurate audio reproduction. Many describe hearing details in songs they never noticed before.
However, some lament the lack of bass impact compared to more consumer/fun-sounding headphones. Electronic, hip-hop, and pop genres may sound dull to those seeking pumped up low end.
Comfort
A common complaint is that the oval earpads are on the small side and put pressure on the ears. Those with larger ears especially find them uncomfortable for long sessions.
But some note the pads soften over time, and aftermarket pads like Brainwavz can also improve comfort.
Value
An overwhelming majority agree these headphones are an incredible value. The performance is on par with models costing over $200 based on the natural sound and build quality.
Reviewers looking for specific features like Bluetooth or active noise cancellation note there are better options if those aspects are needed. But for pure wired studio use, the value is unmatched.
Durability
While mainly plastic, most mention the ATH-M40x feeling solidly built. The metal reinforced headband adds confidence in their longevity. However, the removable cables are proprietary and non-replaceable by standard parts.
Isolation
Many reviewers highlight the good passive noise isolation, allowing them to focus on the audio. The closed-back design prevents sound leakage as well.
Overall
For studio and critical listening applications, reviewers overwhelmingly praise the ATH-M40x as a top choice for those on a budget. The accuracy and detail match more expensive models, cementing their reputation as a go-to affordable studio monitoring headphone.
