The Samsung Level U Pro have a decently stylish around-the-neck design. The sleek, blue neckband fits well and has a smooth, glossy finish that doesn't irritate the skin or catch on your clothing. The in-ear buds have magnetic backs that stick together to make them more manageable when not in use. The in-ear tips are fairly regular. These headphones look decently well-made but the audio cables, on the other hand, are not retractable and feel a little cheap compared to the rest of the build. Weight 0.1 lbs Clamping Force 0 lbs The Samsung Level U Pro are moderately comfortable in-ear headphones as long as you don't mind the around-the-neck design. The neckband is lightweight and flexible so that it won't be too noticeable during long listening sessions. However, if you place the neckband under your clothing, the audio cables that connect to the ear buds will rub against it and transmit the vibration noise to the audio you're listening to. Also, they have pretty conventional in-ear tips, which may be uncomfortable for some. OS Compatibility N/A Ease Of Use Okay Feedback Decent Call/Music Control Yes Volume Control Yes Microphone Control No Channel Mixing N/A Noise Cancelling Control N/A Talk-Through N/A Additional Buttons No The Samsung Level U Pro have an efficient button layout and control scheme. They provide call/music, track skipping, and volume controls. The buttons deliver good tactile feedback, although they're a little small for larger hands. However, the button placement might take a bit of time to get used to. Avg.Temp.Difference 0.8 °C Like the Sony WI-C400, these headphones a have breathable in-ear design. They do not cause any significant temperature increase since they do not cover your ears. They trap a little bit of heat within the ear canal but it's negligible and should not make you sweat more than average. The neckband isn't factored in breathability since they will most likely go over an item of clothing. L 6.63" W 5.88" H 1.5" Volume 58.48 in³ Transmitter Required N/A These headphones are moderately portable. They're a lot larger than typical in-ear headphones (like the Skullcandy Jib) because of the neckband design. However, they are not as cumbersome to carry around on your person as full sized headphones. They easily rest around the neck and can be tucked under your shirt or outfit. Unfortunately, they don't come with a case and won't be portable enough to fit into a pocket. Type No case L N/A W N/A H N/A Volume N/A These headphones do not come with a case or pouch. The Samsung Level U Pro are decently built headphones. The neck band is sturdy yet flexible and won't easily break under physical stress. Unfortunately, the audio cables are a little thin and susceptible to wear and tear compared to the rest of the build. They could snap if they get repeatedly hooked to an item of clothing if you often place the neckband under your outfit. The around-the-neck design of these headphones makes them considerably stable. They won't fall from your neck if you run or jog with them but depending on how well the in-ear design fits you, the earbuds may get a little loose during strenuous exercise. Also, if the neckband is placed under your outfit, the audio cables can get hooked or tangled and pull the earbuds out of your ears.
Sound Bass Amount 3.26 dB Treble Amount -0.88 dB Avg. Std. Deviation 0.31 dB The frequency response consistency is excellent. If the user is able to achieve a proper fit and an air-tight seal using the assortment of tips that come with the Samsung Level U Pro, they should be getting a consistent bass and treble delivery with each re-seat. Std. Err. 2.69 dB Low-Frequency Extension 10 Hz Low-Bass 2.41 dB Mid-Bass 2.35 dB High-Bass 3.84 dB The Samsung Level U Pro have a very good bass. Their LFE (low-frequency extension) is at 10Hz, which is excellent. Accordingly, low-bass, where the thump and rumble common to EDM, Hip-hop and film scores sit, is hyped by more than 2dB. This indicates a deep and extended bass with ample sub-bass. Mid-bass and high-bass are virtually flat, but overemphasized by 2dB and 4dB receptively. This adds a bit of emphasis to the bass guitars and kick drums, but makes the overall sound a bit boomy as well. Std. Err. 2.6 dB Low-Mid 1.07 dB Mid-Mid -3.28 dB High-Mid -2.3 dB The mid-range is very good. The response is very even and rather flat, but there is an 8dB tilt from 250Hz to 700Hz, and a 2dB underemphasis from 700Hz to 2KHz. This nudges vocals towards the back of the mix and gives more emphasis to the bass instruments and lower harmonics of lead instruments. The result is a mix that is slightly muddy and cluttered, and vocals that are a bit thick sounding. Std. Err. 3.47 dB Low-Treble -2.19 dB Mid-Treble -2.67 dB High-Treble -0.12 dB The Samsung Level U Pro have a very good treble performance. The 5dB dip in low-treble negatively affects the detail and articulation of vocals and lead instruments, but the effect will be subtle. The narrow 10dB dip at 8KHz will also have a negative but small effect on the presence of sharp sounds such as S and Ts. Peaks 1.23 dB Dips 1.48 dB Weighted Group Delay 0.12 Weighted Amplitude Mismatch 0.38 Weighted Frequency Mismatch 1.23 Weighted Phase Mismatch 2.2 The imaging is great. Their weighted group delay is 0.12, which is among the lowest we have measured. The GD graph also shows that the entire response is well below the audibility threshold, resulting a fast and tight bass, as well as a transparent treble reproduction. Additionally, the L/R drivers of our test unit were exceptionally well-matched. This ensures an accurate placement and localization of objects (like vocals and footsteps) in the stereo image. PRTF Accuracy (Std. Dev.) N/A PRTF Size (Avg.) N/A PRTF Distance N/A Openness Acoustic Space Excitation The Samsung Level U Pro, like most other in-ears, have a poor soundstage. This is due to the fact that pinna (outer ear) resonance activation is a big part of creating a speaker-like and out-of-head soundstage, but in-ears don't interact with the pinna resulting in a soundstage that is perceived to be inside the listener's head. They also have a closed-back design, which makes the soundstage less open than that of open-back headphones. WHD @ 90 0.103 WHD @ 100 0.056 Isolation Overall Attenuation -15.02 dB Noise Cancelling No Bass -1.66 dB Mid -14.62 dB Treble -30.03 dB The noise isolation of the Samsung Level U Pro is mediocre. These headphones don't have active noise cancellation, and their performance is similar to most other non-noise-cancelling in-ears. They provide very little isolation in the bass range, which is where the rumble of airplane and bus engines sit. However, in the mid-range, important for cutting out speech, they achieve about 17dB of reduction which is good. In the treble range, occupied by sharp sounds like S and Ts, they achieved almost 30dB of isolation, which is also good. Overall Leakage @ 1ft 29.01 dB The leakage performance is great. Not only the overall level of the leakage is quite low, but the range is quite narrow too, limited to 3KHz-8KHz. This results in a leakage that mostly consists of sibilances (sharp sounds such as S and Ts) and will be barely noticeable to people around you, unless you really blast your music in a very quiet place. Microphone Integrated Yes In-line No Boom No Detachable Boom N/A Mic Yes The integrated microphone has an average performance. Speech recorded/transmitted in quiet environments will sound very thin and noticeably muffled. It could also sound a bit sharp and piercing in certain situations, but it will be decently understandable to the people listening to it. In noisy situations, the Samsung Level U Pro perform well and are able to separate speech from ambient noise to a good degree, even in moderate and loud environments, such as a busy street. LFE 507.97 Hz FR Std. Dev. 5.45 dB HFE 3,568.48 Hz Weighted THD 7.458 Gain 38.89 dB The recording quality of the mic is sub-par. The LFE (low-frequency extension) of 508Hz indicates a recorded or transmitted speech that sounds very thin. The HFE (high-frequency extension) of 3.6KHz, suggest that speech will lack detail and articulation, but it will still be decently intelligible. The 15dB peak starting at 2KHz, however, could in certain situations (like with our Pink Noise test signal), make the S and T sounds very sharp and piercing sounding. SpNR 27.71 dB The Samsung Level U Pro's integrated microphone is good at noise handling. In our SpNR test, they achieved a speech-to-noise ratio of more than 27dB, suggesting that this microphone should be able to handle most situations pretty well, except for very loud environments such as subway station. Active Features Battery Type Rechargable Continuous Battery Life 9.5 hrs Additional Charges 0 Total Battery Life 9.5 hrs Charge Time 1.9 hrs Power Saving Feature Auto-Off Timer Audio While Charging Yes Passive Playback No Charging Port micro-USB The Samsung Level U Pro have a below-average battery life of 9.45 hours but have few battery saving features. You can stream audio and charge them at the same time. They also have an adjustable auto-off timer via the bundled app. They won't be the ideal headphones if you don't get the chance to charge your headphones throughout the day but their overall battery performance should be good enough for most users. App Name Samsung Level iOS No Android Yes macOS N/A Windows N/A Equalizer Graphic + Presets ANC Control N/A Mic Control N/A Room effects No Playback Control Yes Button Mapping N/A Surround Sound N/A The Samsung Level app is clean and practical and delivers a good set of features. It has a simple and straightforward interface, two types of graphic equalizers and an adjustable auto-off timer. However, there are no room effects to enhance your audio like some other headphone apps, and the battery indicator doesn't provide enough information. The app is also not available for iOS users which is not ideal.

They also automatically pair to the last synced device once you turn them on. The Samsung Level U pro have a decent latency if you can get a Bluetooth transmitter that supports aptX or aptX(LL). Without the right dongle, they default to SBC which has about 189 ms of latency which is fairly average for Bluetooth headphones but not suitable for watching a lot of video content or gaming.
