Even the HD 4.40 BT’s circumaural (over-the-ear), closed-back design is offered in a matte black finish understated and fine.

Though the earpads are lavish and incredibly comfortable, the headband may use a bit more, adding more listening intervals, it may make its presence known in the kind of noticeable strain on the entire scalp. Still, it’s nothing a little fixing can not mend.

Sennheiser Hd 4.40 Review Design 

There are assorted buttons on the ideal earcup’s side, including the power button, which also puts the cans in the Bluetooth pairing mode (there is also an NFC zone around the left earcup for compatible devices).

Close to the power switch, a button/switch works playback and monitors navigation by pressing or pushing the button forward or backward.

This button also handles telephone calls and summons voice control in your mobile phone. Close this button, there is a committed volume rocker, which functions in combination with your mobile device’s master volume amounts.

Each of these controls is intuitive and just laid out. When it is straightforward to have things like this, it is a surprise, so many businesses get on-ear controls incorrect by attempting to assign a lot of jobs to one button.

The ideal earcup also houses a link for the added 3.5millimeter audio cable. It is excellent that Sennheiser involves a cable, even though we wish it had an inline remote control and mic.

After the cable is attached, it kills Bluetooth pairing as well as the cans immediately power down. The ideal ear is also where the micro USB charging cable joins.

Sennheiser Bluetooth headphones include a free program you can use called capture. The program lets you correct EQ. However, the headphones seem pretty great without them.

Consider it as an elective free additional that in no way detracts from the experience but also does not add much.

The headphones incorporate double omnidirectional mics for superior clarity on forecasts and if using voice controllers.

In our evaluations, the mics offered above-average intelligibility with the Voice Memos program in an iPhone 6s; we could clearly comprehend every word we listed.

On the other hand, the mics may seem somewhat far away, and there is still a sign of Bluetooth noise degradation. But the sound quality is at the higher grade of wireless headset mics we have examined.

Sennheiser quotes battery life should be approximately 25 hours; however, your results will change with your quantity levels. Besides the charging and sound wires, the cans boat with a black drawstring carrying pouch.

Sound Quality

The Sennheiser HD 4.40BT Wireless was analyzed against my Audio Technica ATH-M40x, which includes a comparatively flat tuning. The wireless style was utilized for the review. I utilized my Astell & Kern AK Jr to your audio resource.

The HD4.40 includes a V-shaped sound touch using high mid-bass heat and leaned towards musicality than technicality. Or so it attempts.

The soundstage is quite compressed with an equivalent (or lack thereof) scale of thickness and width. Instrumental separation, subsequently, isn’t striking, and layering is meh.

But again, this can be a frequent attribute in closed-backed headphones, so that I will not be overly harsh in this section. Ed Sheeran’s live recording of Parting Glass sounded terrific, to say the very least.


Starting, the sub-bass expansion onto the HD4.40 is superb. It reaches non into the low frequencies, although not sounding overpowering or too boomy.

Mid-bass is unquestionably elevated over the sub-bass but is restricted and restricted and muddies the lower-mids slightly. The bass is ideal in my view and is well balanced with all the treble. Bassheads should steer clear of this headset as it doesn’t have this punch so that oompf which basophils desire.


The first thing I noticed was the way the lower-mids were recessed than upper-mids. Some is muddying in the bass area, and vocals are a train wreck in my view. Geez, man male vocals appeared nasal and lacked consent.

One of my favorite songs, Layla by Eric Clapton from the album Unplugged was dreadful about the HD4.40.

Nevertheless, female vocals don’t seem nasal and seem more natural, even though it can seem little should short individual tracks. Guitar strums aren’t incredibly crunchy and marginally requires on a back demonstration.


Easy that is how I’d explain the trebles about the HD4.40. Lower-trebles sits on precisely the same amount as the upper mids; hence the trebles could be described as impartial.

Trebles are airy, seeming, and smooth, with no noticeable sibilance or obnoxious peaks. The extension is excellent and rolls off quite late, and trebles are nicely detailed.

Wired Mode

In a wired manner, the audio signature is usually the same as listening to it on with wireless, except that the mid-bass is much more punchy.

The trebles have more of a favorable gradient where the upper-trebles sit slightly over the lower-trebles. I didn’t observe any difference in the mids.


On paths with extreme sub-bass content, such as The Knife’s Silent Shout, the cans deliver a highly effective low-frequency response that does not distort at high volume levels and ought to interest bass fans.

The higher frequencies aren’t forsaken here. There is an excellent balance to the mixture, but that is undoubtedly a bass-forward sound touch.

Bill Callahan’s Drover, a course with much less profound bass from the mix, provides us a much better sense of the general sound touch.

The drums on this course get some serious fostering in the sub-bass kingdom, making them full, around, and wealthy. Callahan’s baritone vocals get lots of low-mid presence to get enough in the high-mids to maintain them fairly sharp and defined.

In addition to the greater enroll percussive hits, the guitar strums with this course have a brightness. The noise this is ball balanced sculpted, with a lean toward the lows, but sufficient significance at the highs.

Jay-Z and Kanye West’s No Church at the Wild, the kick drum loop strike has a sharp edge highlighted well by a marginally sculpted high-mid and higher frequency response.

The drum also gets some severe additional thump from the lows, while the sub-bass synth strikes that punctuate the beat have been delivered with power and depth.

In other words, bass fans will be delighted with the HD 4.40 BT’s reliable signature attracts some serious rumble without forfeiting definition at the highs.

Orchestral tracks, such as the opening scene from John Adams’ The Gospel According to another Mary, seem lively if slightly sculpted via the HD 4.40 BT. Sometimes, we hear a few additional sub-bass thicknesses.

The lower enroll instrumentation seems normal, although the higher enroll metal, strings, and vocals possess a sculpted, clear, crisp audio.

Purists may not fall in love with this audio touch. However, the sculpting is not on the top. There is some compelling of this bass thickness and some tweaking of the highs.

Battery Life

By Sennheiser, this HD 4.40 BT battery life is 25 hours, and a complete recharge takes just two hours. I discovered the battery life to be over 20 hours and got me through a whole eight hours workday while still on excellent quantity.

Comfort And Fit

If you don’t have huge ears, then the Sennheiser 4.40 BT is a comfortable headphone. The earlier paintings are charming and tall. However, the sticks aren’t that broad.

Aside from that, the earpads are satisfactorily cushioned with memory foam, and soft synthetic leather covers them for improved comfort. The earpads may get hot from time to time.

The headset is mild, the headband, although not padded, can also be comfy, and the brute force is enough to hold the headset on the grip without falling when going around.

The headband becomes uncomfortable after a while, and you need to give them a rest or change them after a time.

Packaging and Accessories

The Sound Cable

The package includes a sound cable terminated with a 3.5millimeter jack plus a 2.5millimeter jack on the opposite end. The cable is of the adequate interval but lacks inline controllers to be utilized when connecting the playback apparatus.

When used in a wired manner, the audio quality isn’t too different from the Bluetooth style. Though with Bluetooth, the bass is slightly more than once on the wired manner.

Package And Extra Accessories

Aside from the audio cable, the accessories, and Packaging to your Sennheiser, 4.40 BT is the most Bluetooth headset.

The cans come in a huge black box with the image of this Sennheiser 4.40 BT on front. Within the box, the headset and other accessories such as the sound cable, a USB charging cable, and a storage pouch.

The midrange is shining while the treble is underemphasized.
