The first time I saw two Sennheiser HD 4.40BT and the Sennheiser HD 4.50BTNC I think the 4.50BTNC HD is just a version with more noise of 4.40BT only, but actually not so, HD 4.50BTNC is a better sound quality, compared to the HD 4.40 sound of 4.50BTNC HD with more thickness and detail.
Sennheiser HD 4.50BTNC is the perfect noise canceling headset, the noise-canceling 4.50BTNC noise level is no match for any high-end noise-canceling headset, even when compared to the two best acoustic headphones. Currently the Sennheiser PXC550 and Sony MDR 1000X. You can listen to music comfortably in the most noisy place, such as when you are in traffic, or in a factory or construction, HD 4.50BTNC can eliminate up to 90% of side noise out.
The 4.50BTNC HD ear pads are quite thick, quite comfortable to hold, and the headphones are firmly attached to the ear, which can be used continuously for hours without ear scratches. But the skin is somewhat hard, not as soft as two models of high-end noise-canceling headphones Sennheiser PXC550 and Sony 1000X, long wearing rather hot and earbuds, not very comfortable, but if you are used Ear in the winter is very beneficial, and summer, you must use the condition of air conditioning, if used outdoors with hot weather will be very uncomfortable.
The right hand joystick is quite handy for control, but if you are left-handed, it may be wrong to use it. The response of the joystick is quite fast, with no latency as many low-level headphones.

A headset model aimed at the general user to meet the needs of listening to many types of music, especially POP. So it is no wonder the sound quality of the Sennheiser HD 4.50BTNC is quite V-shape, with warmth, thickness in the overall.
Bass: The bass of the 4.50BTNC HD is quite similar to the bass of the CX, bass is always represented at a slightly stronger than average, the bass is pretty much down, but quite relaxed and tight control. It is almost impossible to overwhelm other negative bands, bass focused and light vibration, creating the background and rhythm of the song very well, without doubt, this is the most valuable tone of the headset. With this bass, the headphones can perfectly play many types of music, from lyrical music to exciting DJs and EDM, but will have some difficulty playing the Rock.
Mid: The midrange is slightly deeper than the bass and treb, but it is warm and light in thickness, the midrange is quite detailed, rounded but not really sweet, something slightly electronic, with substance mid, the headphones really shine in the modern Pop, with the bolero type is not really perfect, but not bad either. Surely this is not a headset for vocal music, if you’re a sweetheart, should not be chosen, because HD 4.50BTNC is a strong, youthful, vibrant medium.
Treb trestle: If only the pop genre, the treble of HD 4.50BTNC is reproduced quite perfectly, very prominent and full but neatly trimmed, making the whole song retains the balanced and bright. You will no longer see the sharp, dazzling but rather soft, smooth.
Sound: The biggest difference between an inear and an over-ear is the depth and breadth of the song space, so you can listen to all day music with the HD 4.50 without feeling tired. Of course, you should not expect too much sound in a closed headset like the HD 4.50BTNC. The best HD4.50BTNC point is the balance between the width and depth of space, all layers of instruments are peeled.
A good, noisy headset with no active headphones at twice the price, the Sennheiser HD 4.50BTNC is a great choice for people who have to move, or do being in a noisy place
