However, it was observed that the larger size may contribute to the overall weight of the headphones, making them slightly heavier than some competitors. To further enhance the fit during extended use, we recommend using headphone pads made with breathable materials like leatherette or memory foam, as well as adjusting the headband tension for optimal comfort. Overall, the large oval cups make the Sennheiser HD 650 headphones an excellent choice for listeners who prioritize comfort during long listening sessions, making them suitable for work or marathon listening sessions.

1. What makes the Sennheiser HD 650 headphones stand out compared to other audiophilegrade openback headphones in their price range?

The Sennheiser HD 650 headphones differentiate themselves from other audiophile-grade open-back headphones in their price range by offering superior sound quality with a spacious soundstage, excellent bass depth, lush mids, and a slightly rolled-off treble. Additionally, they provide increased comfort during long listening sessions due to large oval ear cups with an ergonomic design.

2. How does the large oval ear cup design contribute to increased comfort during long listening sessions?

The large oval ear cups in the Sennheiser HD 650 headphones contribute to increased comfort during long listening sessions by providing ample space for larger ears and improved circulation around the ears, reducing pressure points that can lead to discomfort or soreness over time. This design choice makes them suitable for marathon listening sessions, work sessions, or long commutes, as they offer a more ergonomic fit than circular ear cup designs, enveloping the ears without applying too much force. The oval shape ensures comfortable and fatigue-free use even after extended periods of wear.

3. Are the Sennheiser HD 650 headphones suitable for use in public settings such as commuting or bus rides, given their sound leakage?

The open-back design of the Sennheiser HD 650 headphones does result in some sound leakage due to their open-back nature. However, this may not be a significant issue for casual listening in public settings like commuting or bus rides, as they are not designed to isolate sound as much as closed-back or active noise-cancelling headphones. Consider using noise-isolating earplugs or reducing volume levels if privacy is a priority when using the Sennheiser HD 650 headphones in noisy environments.

4. Can I adjust the tonal balance of the Sennheiser HD 650 headphones using equalizer settings or external EQ tools like Sonarworks Reference 4 or JST?

Yes, you can adjust the tonal balance of the Sennheiser HD 650 headphones by using equalizer settings or external EQ tools like Sonarworks Reference 4 or JST. By fine-tuning the frequency response, you can tailor the sound signature to your personal listening preferences and compensate for any perceived weaknesses or strengths in the stock tuning. This can help enhance overall clarity and precision when listening to specific genres of music with challenging treble content like electronic or hip hop.

5. What additional equipment is required to obtain the best possible sound quality from the Sennheiser HD 650 headphones?

To attain optimal sound quality from the Sennheiser HD 650 headphones, a high-quality DAC and amplifier are highly recommended. A tube amplifier like the Bottlehead Crack with Speedball upgrade is suggested for an engaging and musical listening experience due to its warm sound character. However, other sources of audio playback such as smartphones, laptops, or portable music players may not be able to provide sufficient power to drive the headphones, resulting in reduced performance.

6. Are there any potential limitations of the slightly rolledoff treble in the Sennheiser HD 650 headphones that users should be aware of before making a purchasing decision?

Yes, one potential limitation of the slightly rolled-off treble in the Sennheiser HD 650 headphones is that it may make discerning details in complex audio tracks with lots of high frequency content like electronic or hip hop music more challenging. Users who value a bright and sparkling treble response may find this characteristic less appealing, while others may appreciate the relaxed and warm sound signature for fatigue-free listening sessions over extended periods. It's essential to consider personal preferences when evaluating the rolled-off treble in the Sennheiser HD 650 headphones before making a purchasing decision.
