The Bluedio U Plus are decently sturdy and comfortable wireless headphones with a sleeker design than the rest of the Bluedio lineup. Unfortunately, they have a sub-par sound quality that may be a deal breaker for most, especially at their price range. They're also a bit too bulky for sports and do not block enough noise to use in loud environments.
- Sturdy build quality.
- Decent wireless range and battery life.
- Efficient control scheme.
- Poor sound quality.
- Below-average Noise isolation.
- Bulky design.

The Bluedio UFO Plus have a sleeker form factor than the rest of the Bluedio lineup but are considerably bulkier. They're easier to use and more comfortable than the rest of the Bluedio headphones but they're still a bit tight on the head which might get fatiguing after a while. They're relatively easy-to-use and decently sturdy but unfortunately, their size and weight make them a bit difficult to carry around on your person and too unstable for running or jogging.
The Bluedio U plus have a very different look to the Bluedio Turbine line up. The hinges rotate instead of folding and do not protrude outwards which give the U-Plus a more sleek design. They look and feel like the Beats Pro and even have the same daisy chain and locking mechanism for the audio cable. They come in two color schemes; black and white, and are they're also considerably larger and stand out more than the other models in the Bluedio lineup.
The Bluedio U Plus are above-average comfortable headphones. They're well padded and have sufficiently large ear cups to fit most listeners. However, they're a bit tight on the head and relatively heavy so they may get fatiguing after a while.
The Bluedio U Plus have a much better control scheme than on previous models. The buttons are clicky and ergonomically laid out on the right ear cup. They provide the essential functions; call/Music, track-skipping and volume controls. They also have an additional feature that lets you switch between EQ effects by holding the track skipping buttons. Forward to turn on the effect and Rewind to turn off.
The Bluedio U Plus are somewhat portable thanks to their folding design. However, they're still quite large headphones compared to other mid-sized over-ear models. They're not the easiest to carry around on your person but when folded they take up less space and should easily fit in your bag.
The Bluedio U are decently well-built but not as durable as the much cheaper Bluedio T4. They have a sturdy metal frame to reinforce the headband and the ear cups are decently dense. They won't break easily from a couple of drops but the enclosures of the ear cups feel a lot cheaper than that of the T4s. The revolving hinges are also potential weak points that may loosen over time.
The Bluedio UFO have a tight fit that prevents them from being too unstable. They're also wireless so they won't get yanked off your head because the audio cable got caught on something. However, they are bulky and heavy headphones so they sway a lot when running so they won't be the ideal headphones for sports.
The Bluedio U Plus are a poor sounding pair of closed-back over-ear headphones. They Image relatively well, perform similarly on most individuals, and have an average distortion performance. However, their Bass Range is overpowering and boomy, their Mid Range is practically non-existant and their Treble Range is inconsistent. Also, like most other closed-back headphones, they don't have a spacious and open sounding Soundstage.
Poor Bass Range performance. The response is relatively flat, but consistently over our target by more than 7dB. This makes the Bass of these headphones quite overpowering and boomy.
Poor Mid Range performance. Low-mid and mid are practically missing, due to the 15dB dip surrounding 500Hz. This significantly pushes vocals and leads to the back of the mix. On the other hand, high-mid is relatively flat and well-balanced.
Poor and inconsistent Treble Range performance. Low-treble is slightly overemphasized, adding a bit of tinny quality to the sound. The dip around 7KHz hurts some of the sibilances (S and T sounds) to the point of making the sound lispy. Conversely, the peak around 10KHz will have the opposite effect on some higher frequency sibilances, making them sharp and piercing.
Average Consistency performance. In the Bass Range, these headphones perform quite consistently across our multiple human subjects, except for our subject who wears glasses. It seems that glasses could break the air-tight seal that these headphones need for creating their Bass and cause more than 3dB of drop in Bass below 200Hz. In the Treble Range, their consistency is good.
Decent Harmonic Distortion performance. The UFO Plus shows elevated amounts of distortion in the Bass Range, but humans are less sensitive to low frequency harmonic distortion. The bump around 500Hz, corresponds to the dip in the frequency response of the same range making them less audible. The sharp peaks in the Treble Range however, could make those frequency slightly harsh.
The Bluedio UFO do not block noise very well. They won't be the ideal headphones to use in loud environments especially in areas with a lot of low-frequency noise. They will easily let the rumbles and chatter of a busy metro or bus seep into your audio. They're also a bit leaky at higher volumes so they won't be the best headphones to use in quieter settings but at average volumes, they shouldn't be too distracting.
Poor Isolation performance. The Bluedio U headphones don't have active noise-cancellation and isolate only passively. They achieve no isolation in the Bass Range. In the Mid Range they achieve about 9dB of reduction, which is decent. In the Treble Range they reduce the outside noise by more than 34dB which is good.
Mediocre Leakage performance. The significant portion of the leakage sits between 500Hz and 5KHz which is a relatively broad range. The overall level of the leakage is also relatively high, especially around 3KHz.

The Bluedio U Plus have a slightly short wireless range but an above-average battery life. They also have less latency than some of the other Bluedio models but won't be the ideal headphones for watching movies or videos as the latency is still quite noticeable. Unfortunately, they take a while to charge and don't have many power saving features. They also do not have a companion app to customize their sound profile especially considering their default audio reproduction is not great.
The Bluedio UFO have an above-average battery life of 20 hours but take a considerably long time to charge. They don't have an auto off feature but can charge while playing. They can also be used completely passively with the audio cable, which makes them a decent option for the office.

The Bluedio UFO have a slightly below average wireless range when the Bluetooth source is obstructed. They reached just above 25ft but in direct line of sight, they performed much better reaching about 120ft. It should be enough range for most casual applications and they're also not too difficult to pair. Although they do not support NFC, pressing and holding the multi-function button when turning the headphones on puts them in pairing mode relatively fast.
The Base Latency of the Bluedio U Plus is a bit better than most Bluetooth headphones. However, it's still a bit too laggy for watching movies and gaming. You may get used to it during long videos but it won't be the most pleasurable viewing experience.
