Sennheiser HD 650 – Hi-Res Open Back Dynamic Headphone
The Sennheiser HD 650 is a high-end, open-back dynamic headphone that ensures an extraordinary sound experience. It is primarily designed for professional audio engineers, producers, and passionate audiophiles who crave accurate and superior sound quality from their audio playback devices.

The Sennheiser HD 650 features hand-selected matched driver elements, highly optimized magnet systems, and computer-optimized magnet systems. These all come together to minimize harmonic and intermodulation distortion to provide a more sonically accurate output.
The open-back design provides a spacious soundstage and excellent stereophonic sound. The ear cups have been structured to direct the sound waves to the ears at a slight angle. This results in a more natural and realistic listening experience.
A high-quality titanium/silver finish gives the headphone a professional aesthetic that matches its performance. Moreover, the breathable, velour ear cushions offer excellent comfort for extended listening sessions. The robust construction guarantees long-term durability.
It’s worth noting that the HD 650’s high impedance (300 Ohms) might require the use of a headphone amplifier to realize its full potential. This makes it more suitable for professional studio settings or a dedicated home listening room than for casual, on-the-go use.

bad
Lack of Noise Isolation
- The HD 650 headphones are open-back, which means they do not provide any form of noise isolation. This can be a deal-breaker for those who want to use their headphones in noisy environments.
Price
- The price tag might be prohibitive for some potential buyers. Despite being a top-tier product, not everyone is willing to invest this much money on a pair of headphones.
Sound Leak
- As with other open-back headphone models, sound leakage is a significant issue. People nearby might have an uninvited preview of your playlist.
Size and Weight
- The HD 650 headphones are not the most compact or lightest headphones on the market. This could make them uncomfortable to use for extended periods, especially for individuals with smaller heads or those prone to discomfort from heavier headphone models.
Non-detachable Cable
- Another downside is the lack of a detachable cable. A fixed cable limits portability and increases the risk of wire damage.
No Inline Controls
- The HD 650 lacks inline controls, meaning that when you need to control your music or answer calls, you’ll have to do this directly from the connected device. This can be less convenient for users who prefer to control their audio on the go.
Audiophile Quality May Not Suit All Listeners
- These headphones have been crafted with audio precision in mind which makes them great for audiophiles, however, the average music listener may not feel the need for such audio accuracy, which might make the high cost of these headphones seem unnecessary.
