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.
What you expect first and foremost from Sennheiser is great sound quality and the HD4.40s certainly do not disappoint. Clear crisp high and mid with punchier bass than in my other Sennhieser headphones, hd558s are open back so bass isn't expected. These are warm I truly love the sound for listening to music of any type and they serve well for podcast as well.
The build quality is solid and not the most premium but for the price it's expected and they do feel and look good and are strong, Sennhieser typically uses premium materials and the surfaces all feel great just not a lot of metal or leather. Although the leather earcups are better than my Bose and Sennhieser Momentums. I do like how they fold up to easily fit in my bag.
Wireless is the main reason I bought these because I wanted a great sounding over ear headphone and I knew Sennhieser wouldn't let me down and they've blow me away. Range is great and the battery lasts for days with 24hr use advertised. If you are using them for bursts they are gonna last along time which is huge for me.
I'd tell you to go buy these if you want a very nice sounding over ear Bluetooth headphone I can't see how these would let anyone down. I'll update if anything changes.
UPDATE: So I fully charged the headphones when I first got them and I've used them for over 8 hours of use with days in standby and I'm not kidding the batter is still at 97%. Really incredible battery life, amazing sound for the price. They sound much better than my Bose Soundtrue 2 and those cost more and aren't Bluetooth although the Bose are more compact. I'm so impressed with the battery life his far. Will update further in a few weeks.
One negative thing that has happened is that the Sennhesier brandin in the top band has completely worn off. It isn't scratched there, no damage it just wore off over time. Pretty sad even though it's not a big deal. I won't take a star off for it I but I think Sennhesier overlooked what they used to print that branding with.
I'm a not bass-head, but I don't think bass is as heavy as a real bass-head would expect..
It is entirely plastic, but doesn't look cheap..
I feel that the ear cups are bulky, but the ear pads (inner dimensions) are a little narrow. Look at the pics in which I've shown the comparison with the ear pads of Momentum2.0 and RS 160. I personally like the ear pads to be more roomy for comfortable listening for longer periods. These narrow ear pads may cause discomfort to those having medium and large ears. This is perhaps the only drawback.
All in all this is a good value for money product since it is very competitively priced.
