Our Verdict
Decent for neutral listening. The Sennheiser 4.40 have a good, powerful, and extended bass, a well-balanced and accurate mid-range, but an underemphasized treble range that lacks in detail. Also, their bass is slightly thumpy, which some may like, but is also inconsistent across different users. Overall, these headphones will be suitable for a wide variety of music genres, but they have a slightly darker sound overall, and vocals and cymbals will sound a bit bland. On the upside, they have a good EQ, which lets you customize their sound to your preference.
- Fairly comfortable and durable design.
- Low latency for Bluetooth headphones.
- Great battery life.
- Sub-par isolation performance.
- Bass is prone to inconsistencies across users. Sensitive to glasses.
Passable for commuting. The Sennheiser HD 4.40 aren’t the most portable headphones and they lack an ANC feature like similar Sennheiser models. They don’t isolate at all against lower frequency noises like engine rumbles. On the upside, you’ll be able to use them during the longest flights, as they have a great 29-hour battery life.
- Fairly comfortable and durable design.
- Low latency for Bluetooth headphones.
- Great battery life.
- Sub-par isolation performance.
- Bass is prone to inconsistencies across users. Sensitive to glasses.
Okay for sports. The headphones feel secure and stable on the head for jogging, but they are noticeably less tight than the Sennheiser HD 4.50. Also, their bulky over-ear design won’t be ideal, as it traps heat under the ear cups, and they aren’t very portable. Their control scheme also isn’t the best, and might be hard to use during exercising.
- Fairly comfortable and durable design.
- Low latency for Bluetooth headphones.
- Great battery life.
- Sub-par isolation performance.
- Bass is prone to inconsistencies across users. Sensitive to glasses.
Okay for the office. These headphones passively isolate well against A/C noise and do a decent job against ambient chatter, especially if you're playing a bit of music. They also don’t leak too much, so you’ll be able to block more noise by raising your volume without disturbing your surrounding colleagues. Additionally, their great battery life will last you longer than a full workday, but some might need to take a break because their headband lacks padding.
- Fairly comfortable and durable design.
- Low latency for Bluetooth headphones.
- Great battery life.
- Sub-par isolation performance.
- Bass is prone to inconsistencies across users. Sensitive to glasses.
Mediocre at best for gaming. Playing video games over Bluetooth is not ideal, even with latency that is lower than most Bluetooth headphones. Also, their microphone is mediocre and won’t be suited for talking with friends and teammates online.
- Fairly comfortable and durable design.
- Low latency for Bluetooth headphones.

- Sub-par isolation performance.
- Bass is prone to inconsistencies across users. Sensitive to glasses.

Popular Headphones Comparisons
The Sennheiser HD 4.40 are decent mixed-usage headphones that set themselves apart by their amazing wireless range and low latency, which makes them more suitable to watch video content than most Bluetooth headphones. However, they don’t have a great isolation performance, since they lack an ANC feature like other similar Sennheiser models. If you’re looking for ANC headphones for your commute, take a look at our recommendations for the best headphones, the best noise cancelling headphones and the best over-ear wireless headphones.
The Sennheiser HD 4.50 are more versatile headphones than the Sennheiser HD 4.40 BT due to their ANC feature, which makes them suitable for commuting and at the office. Other than that, these two models are practically the same and perform quite similarly. The HD 4.40 are a bit less tight on some heads, which can be more comfortable for people with bigger heads.
The Sennheiser HD 4.40 BT Wireless might be a better option than the JBL E55BT Wireless for most users, thanks to its nice app that allows you to EQ the sound to your liking. They also have very low latency for Bluetooth headphones and have a few more hours of battery life. The JBLs are slightly more comfortable and can pair with two devices simultaneously. They also come with a cable that has an in-line microphone, which the Sennheiser lacks.
The Sennheiser HD 4.40 BT Wireless are better mixed-usage headphones than the Skullcandy Hesh 3 Wireless, thanks to their app that gives you access to a good EQ. The Sennheiser also have less latency, which is good for watching videos. Other than that, they are similarly performing headphones and both have a very similar look. The Skullcandy might be a better choice if you like bass-heavy genres.
The Sony WH-CH700N are slightly better headphones than the Sennheiser HD 4.40 BT. They have a great audio reproduction and have over 30 hours of battery life. Their control scheme is noticeably easier to use, and they have an ANC feature, though it doesn’t seem to isolate against ambient noise that well. The Sony app is also great and offers multiple controls and customization. On the other hand, the Sennheiser headphones have low latency for Bluetooth and take noticeably less time to charge. However, they won’t be as comfortable as the WH-CH700N.
