    • Review After 60-days of Daily Use
Color: Black
The Short: Affordable, dependable, over-ear bluetooth headphones with high usability, rich sound with good separation from trusted brand in audio. I run a professional video and photography production company, and use these headphones on a daily basis for both editing and entertainment. If you are considering this pair of headphones, odds are you are simply looking for a pair of wireless bluetooth headphones with the best quality sound that can hold up to casual daily use. Congratulations, you’ve found it. The tech specs are readily found on Amazon and Google, so I won’t get into the technical side in this review. Instead, I will talk about (1) build quality + durability, (2) reliability, (3) sound quality, (4) usability, (5) comfort, and (6) transportability. 1. Build Quality + Durability The headphones are made with hard plastic all around; there are no visible metal parts on the headphones. They are lightweight, but overall construction feels solid and the plastic feels and looks like high-quality plastic and not cheap and toy-like. I travel a lot for my work — spending my days between editing out of coffee shops to flying across the country on production. The headphones either travel with me around my neck, folded in my padded equipment bag, or folded into my daily commuter backpack without any hard case around it. In all instances, over the last 2 months of daily use, I have never had any issues with the headphones nor have I had to worry about them not holding up to travel. So far so good! 2. Reliability One of the most important factors for me in choosing a bluetooth wireless headphone was the reliability of the connection. I grade this on (a) the connection strength of the headphones and (b) the ability of the headphones to connect with my devices every time. These headphones have performed with perfect marks across the board in both categories. I’m an Apple user, and use these headphones daily between my iMac desktop, MacBook Air laptop, and my iPhone X. The bluetooth connection is always solid, and the sound coming through is clear with no audible lag, distortion, nor interference. If using with just one device, the headphones will pair quickly and automatically, which is nice. Switching between each device has been super easy for me — just hold the power button down when turning the headphones on to place the headphones into pairing mode, then select the headphones from your device’s bluetooth pairing menu. 3. Sound Quality These have great sound clarity, rich midtones, controlled highs, full base (but not overwhelming), and remarkable sound separation. The headphones may be used both wirelessly, or with the wire that comes with the headphones. As with all wireless/bluetooth headphones, the audio quality is always better if directly connected to the device. However, these headphones do a truly fantastic job of preserving audio quality in wireless bluetooth mode. I would say there is a negligible difference in sound quality between wired and wireless, which is really only noticeable if you are comparing it side-by-side. I was a long-time user of the Beyerdynamic DT 770 PRO 80 Ohm wired studio monitoring headphones, which are still my headphones of choice when monitoring sound on film productions due to its flatter profile which allows me to hear frequencies on a or even spectrum. On the contrary, the Sennheiser HD 4.40’s noticeably richer and more responsive tones and fuller base makes it more enjoyable to listen to, despite being less than HALF the price. If you want a pair of headphones that enable you to ENJOY your sound and not just monitor it, I definitely recommend these headphones. Even in their wireless mode, these headphones have allowed me to hear and feel MORE from old music I’ve heard many times before. 4. Usability I spend a lot fo my time between my desktop, laptop, and cell phone for work. The pairing and switching process is super easy., and I have never had any issues with these headphones with any of my devices. I have used these for a full day of flying and traveling, and did not run into any issues with battery life, which Sennheiser boasts as having up to 25 hours of battery life while in wireless mode. The controls on the right ear cup of the headphones are easy to access for me, though toggling them produces an audible “beep” from the headphones while in wireless mode. Many of complained about how annoying this beep is, but I personally don’t mind having audible feedback to my input. Using the headphones in wired mode disables the functionality of the buttons on the right ear cup, thereby eliminating the “beep.” 5. Comfort The ear cups that come with the headphones are made of a supportive but super soft memory-foam type material, covered by a smooth and high-quality feeling stitched pleather material. Many of complained that the ear cups are too small to fit over their ears, and should therefore be considered on-ear headphones, though I have never had that problem myself based on my ear-size. My ONLY complaint is that the padding on the bottom of the headband where the band touches the head does not have very much padding, which can create some discomfort when wearing over a long period of time. I have the headphones at their max extension to avoid tension from the headband hurting the top of my head. The headphones stay on my head very well and does not slip around despite being on the widest setting. 6. Transportability To transport, the headphone’s ear cups fold INTO itself, though the ear cups do not fold flat. As a result, they produce a taller profile vs. headphones that fold flat. When I travel, the headphones are either around my neck for ease of access, or folded and placed into my padded equipment case, equipment backpack, or simply tossed into my daily commuter backpack. They really are a fantastic pair of wireless bluetooth headphones for the commuter and daily user who wants to enjoy their sound. -------------------------------- Conclusion: For their price range ($70 at the time of this review), they are really hard to beat. If you are looking for a pair of headphones for entertainment and not professional/commercial use, it's hard to go wrong with the Sennheiser HD 4.40. Great for the commuter and daily user. Would buy again. ... show more

    • Some fantastic features. Some disappointments too.
Color: Black
I was officially eager to get the Sennheiser HD 4.40BT headphones. After trying out several headphones and accidentally coming across the HD 4.40s during a web search I thought, this is it. Finally, the pair I’ve been looking for. Some reviews say they sound great. They do. Some reviews say that their phone voice quality is good. It’s okay. And, for me, which is a critical issue, the reviews say that the HD 4.40 prevent sound leakage very well. That one is very true. So initially, I thought that I found the nearly perfect pair of headphones. But it turns out there are some disappointments especially when referring to my secondary list of “must haves”. Not critical, deal-breaker features, but ones that I find very convenient and in some cases essential, I started to find the shortcomings of the HD 4.40BT. But first, let me comment on their sound quality. I’ve tried the Bose QC35, Sony MDR-1000Xs, Sony MDR-XB950BTs, Skullcandy Crusher Wireless, and the Plantronics Backbeat Pro 2. These headphones perform stellar in the sound quality department. Clear crisp highs, full mids, and plenty of bass. But the most fun I have with these their sound stage. With the HD 4.40BT, you get a broad sound stage with great separation. If you’re looking for a great sounding pair of headphones at $150, you’ve found them. These are the least expensive of the lineup I’ve tried and yield a sound quality on par or better than all of the headphones I’ve tried at more than twice the price. The phone call quality is okay on the Sennheiser HD 4.40BT. Sometimes I get callers telling me that I sound fantastic and sometimes that I have digital “reverby” artifacts. Unfortunately, I can’t get consistent results. I do know that when I switch to my phone during those complaint calls, I get good responses. So it’s definitely in the headset. It may be a futile effort to find a great sounding pair of headphones that has excellent call quality but I’m trying. For now, the search continues. The noise isolation capability is not that great. I can clearly here ambient sound, voices, and the like while listening to music, even somewhat loudly. Fortunately, however, these do not leak much sound which is a huge bonus. Due to the less-than-ideal noise isolation, I may try out the Sennheiser HD 4.50BT instead. Since those feature noise cancelling. The HD 4.40BTs fold for compact storage, which is very nice. I wish the ear cans also rotated flat as with other headphones I’ve tried. But I mostly like the rotated ear cans for comfortably wearing the headphones around your neck when you need to temporarily have them removed. Fortunately, the HD 4.40s are very comfortable around the neck without this option. I think it’s their wide headband that accounts for this. Overall the foldability is nice. These come with a soft pouch so you’re not going to get any protection from a case with the HD 4.40BTs, but at their price-point, the company had to skimp somewhere. The controls are okay. And if you’re familiar with Sony MDR-XB950BT controls, you’ll find these pretty similar. There is one significant difference however, the Sony’s feature a multi-function button that is pretty tall, which makes it easy to accidentally skip or rewind your music instead of pausing. This is due to the leverage that their button height has. This potential issue is not an issue on the HD 4.40s because the multi-function button has a very low profile. Consequently, the buttons low profile makes it a bit more difficult to find and press for phone calls and pausing music, especially since the bezel around the ear cup that has nearly the same height as the low profile multi-function button. The volume rocker is placed low on the ear can which I find a little too low. I think an improvement to the design would be to move the power button to the front of the can and allow more spacing and better positioning of the volume rocker and play/pause multi-function button. Overall, they’re a solid set of buttons that work well to control calls and music. The ear pads, as mentioned in other reviews, have small openings and while I don’t have very large ears, the ear pad openings do press on either the top or the bottom of my ear depending on how I position them. This is in contrast to the Bose QC35s which have a large opening that fit my ears comfortably without touching. Despite this issue, the ear pads on the Sennheisers are soft and the headsets light enough to make them comfortable. However, I find myself having to tweak the fit ever time I use them. The comfort tolerance is so tight that you have to really fuss with the fit to get them where you can wear them for hours without some discomfort. It’s possible to find the sweet spot, but you need narrow ears, a narrow head, and a bunch of finicky trials to make them fit nicely comfy. There is a noticeable amount of ear pressure after wearing these for over an hour so they’re not the most comfortable headphones you can find. I wish Sennheiser would have made the ear openings bigger because the suppleness of the ear pads is great. There is minimal padding in the headband which will apply pressure to the crown of your head after about an hour of wearing these. In summary, larger ear pad openings and a more heavily padded headband cushion would make these extremely comfortable. As designed, they’re not. The LED light on these does not illuminate when the headphones are on. While I thought this would be a bonus, especially when using them in a dark room, believe it or not, I miss a flashing or glowing LED. Glowing LED lights help let you know if a device is on, which may help you avoid unnecessary battery drain. With the HD 4.40s you’ll have to either look at your device to confirm whether they’re on or not, or you’ll have to simply try to play audio through them to test if they’re on. One last little disappointment is the 2.5 to 3.5 mm headphone cable. I have a few standard 3.5mm cables lying around and would like to keep those in different places for convenient use with my headphones. One in the computer bag, one at the office, one at home, etc. Unfortunately, you need a special cable with the HD 4.40BTs. If you’re looking for a good pair of headphones that sound great, have decent comfort, prevent sound leakage for using them in work environments, and have adequate voice call quality the Sennheiser HD 4.40BT may give you everything you want. Overall, feature and sound-wise these headphones top the Bose QC35, Sony MDR-1000X, Sony 950BT, the Plantronics Backbeat Pro 2, and the Skullcandy Crushers. While they're not perfect, they do have some solid performance in the features they offer. ... show more
