The SMS Audio STREET by 50 Active Noise Cancelling are fashion-forward headphones that look stylish and deliver decent bass-heavy audio reproduction. They feel relatively sturdy but the poor noise isolation performance means they should not be your first choice to cancel out ambient noise from noisy commutes.

Black STREET by 50 Active Noise Cancelling
Silver STREET by 50 Active Noise Cancelling


The STREET by 50 Cent Over-Ear are a good looking pair of headphones. They feel sturdy enough to handle a few drops and the large ear cups encompass the ear well, creating a decent seal. Unfortunately, they are slightly heavy, the headband creaks a lot under stress and the ear pads are stiff, which reduces their overall comfortability once on the head.


The SMS Audio STREET by 50 have a stylish matte black design that looks modern but is slightly bulky. They have bright blue accents on the stiching of the underside headband and the provided cable. The ear cups have a black glossy coating that adds a little more flare and the padding has a faux-leather texture that gives it a high-end esthetic.

6.5 Comfort
Weight : 0.68 lbs
Clamping Force
1.11 lbs

Comfort level for the Street by 50 is decent but could be better. They are slightly heavy, have stiff padding on the ear cups and the headband puts moderate pressure on the head, which is uncomfortable over long listening sessions. However, the over-ear design does encompass the ear successfully, which is a plus.

5.3 Controls
Ease of use : Good
Feedback : Average
Call/Music Control : Yes
Volume Control : No
Noise Canceling Control : No
Talk-Through : No
Additional Buttons : No

Button layout and functionality is simple but basic. There is only one button to enable noise cancelling and the rest of the controls are relegated to the inline control of the cable. Unfortunately, the inline control is only a call/music button with no volume controls, which is slightly disappointing.

6.5 Stability

The SMS Street by 50 cent are moderately stable headphones. They stay in place during casual listening sessions. The broad headband helps the earcups sway less during physical activity but not enough to comfortably use these headphones at the gym. They will slip off your head while running or jumping but on the upside, the cable is detachable and won't pull the headphones of your head if it gets hooked on something.

5.8 Portability
L : 5.91 "
W : 7.28 "
H : 3.15 "
Volume : 135.47 Cu. Inches
Stand required : N/A

The SMS street by 50 are below-average portable headphones. They fold up into a more compact format but are on the larger side for over-ear headphones and still take up a lot of space in a bag.

7.0 Case
Type : Soft case
L : 6.1 "
W : 7.87 "
H : 3.94 "
Volume : 189.1 Cu. Inches

Comes with a stylish, soft case that will protect the headphones against scratches. However, it does add a little bit of bulk and doesn't shield the headphones from hard falls or water damage.

6.5 Build Quality

Build quality is decent but not great. These headphones feel relatively sturdy and the metal frame, though a little thin is solid and flexible enough to handle a fair amount of physical stress. Unfortunately the headband is a little creaky and they do not feel as robust as some other headphones within their weight and size.

5.8 Breathability
Avg.Temp.Difference : 7.5 C

Detachable : Yes
Length : 0 ft
Connection : 1/8" TRRS

Comes with a 1/8" TRRS-TRRS with call/music but no volume control and a USB charging cable.



The SMS Audio STREET are a mediocre sounding pair of closed-back over-ear headphones. They have a sub-par bass, a good mid-range, and a poor treble. Additionally, their bass lacks sub-bass and is uneven, their mid-range is slightly forward sounding, and their treble doesn't have enough detail and presence. On the plus side, they don't produce too much distortion.

The SMS Audio Street by 50 struggle with noise isolation. They do not block much sound actively, the noise cancellation technology only mildly improving the passive isolation provided by the seal the ear cups. They may not be the right choice for international travel, as a lot of low frequency ambient noise will seep into your listening experience. However, the seal does prevent a decent a mount of sound leakage.

6.5 Noise Isolation
Overall Attenuation
-15.18 dB
-3.78 dB
-12.87 dB
-31.5 dB
14.67 dB

Sub-par noise isolation, especially in the bass region. These headphones seem to be adding a few dBs of their own low-end noise, which may be noticeable in quiet situations. The mid and treble isolation is decent, maxing out at -14dB and -34dB respectively.

2.7 Leakage
Overall Leakage @ 1ft
59.46 dB

The profile is rather broadband (covering high-mid and low-treble), but the overall amount of leakage is small enough for that not to be a big problem in most situations.


Active Features

The Street by 50 only have noise canceling as an active feature. This makes them less versatile for other use cases except as noise canceling headphones, as they lack both wireless features or an app, to enhance and customize their sound. On the upside, the rechargeable battery delivers an excellent 57.1 hours of continuous playback, but have no power saving features and take quite a bit time to charge.

The SMS Street by 50 deliver a great battery life but take a bit long to charge. They're decent headphones for long flights or road trips but do not have any battery saving features like an auto-off timer and can't continue playing audio when charging.

5.8 Mixed Usage

Below-average for mixed usage. They're bulky headphones that leak a lot and feel cheaply built. They're a little uncomfortable but have a decent but bass heavy sound that might work for some listeners.

6.6 Critical Listening

Average for critical listening. They have a slightly bass heavy sound that lacks a little detail with instruments and vocals. They also do not sound as immersive due to their closed-back ear cups which won't be ideal for more critical listeners.

5.8 Commute/Travel

Subpar for commuting. They block enough noise to use on the bus but they're also not very portable leak enough to be distracting and lack a good control scheme.

5.6 Sports/Fitness

Not made for sports. They're cumbersome and too unstable for sports.

5.0 Office

Poor for office use. They will block some of the office chatter but leak way too much to be a good option in quieter environments.

6.4 Home Theater

Average for home theater use. Since they're wired, they have no latency, but the cable is not long enough unless you're watching your movie on a PC or tablet. They're also not the most comfortable headphones to wear for long periods of time.
