The JBL E50BT are stylish, wireless headphones with a decent sound and a sturdy, durable build. They have a well-crafted design but oddly shaped ear cups that don't fit properly around the ears. Unfortunately, this creates a poor seal that lets noise seep into your audio and also leaks quite a bit.
- Above-average audio reproduction.
- Sturdy and durable build.
- Great wireless range.
- Poor noise isolation.
- Leaky at moderate-to-high volumes.
- Awkward ear cup fit can be uncomfortable.
The JBL E50BT are rugged yet stylish and feel somewhat high-end. They're not as well made as some premium headphones we've tested, but they have a sturdy frame and dense ear cups that can handle a few drops without getting damaged. Unfortunately, the oddly sized ear cups are also uncomfortable. They're bulky, cumbersome headphones to comfortably carry on your person and they're not stable enough to use while jogging.
The JBL E50BT have a good design that gives them a more premium appeal than their price point would suggest. They have circular and flat ear cups that do not protrude outwards once on your head. The headband and frame are wide and look sturdy. They come in a variety of color schemes to suit your tastes. They won't be the ideal looking headphones for everyone, and the hinge mechanism looks a little awkward.
The JBl E50BT have oddly sized ear cups that don't quite encompass the ears. Therefore the fit is somewhere between an over ear and an on-ear design, which unfortunately means they won't be the most comfortable for listeners with larger ears. They're not too tight but the rigid padding and the awkward fit exerts pressure on the tip of your ears, which gets uncomfortable during long listening sessions.
These headphones offer good button placement and functionality. They provide call/music, track skipping, and volume controls, which can all be found on the left ear cup including the power/Bluetooth sync button. The controls do not feel cramped and are well laid out. However, the buttons are flat with no tactile indicators.
The E50BT are moderately stable. They're sufficiently tight on the head and won't move much during casual listening sessions. However, they're not sports headphones. They're bulky and will quickly fall when used while running or jogging. On the upside, the wireless design makes them less likely to be yanked off your head due to the audio cable being hooked on something.
These headphones are not the most portable. They fold into a compact format and the ear cups also lay flat. Although due to the wide headband this doesn't save much space. They're a little on the larger side for over-ear headphones and will be cumbersome to carry on your person without a bag.
The JBL E50BT have a pretty sturdy build quality. The ear cups look robust and dense enough to handle a few drops without getting damaged. The headband and frame are also relatively thick and flexible and should be able to withstand moderate-to-high physical stress. However, the hinge mechanism only connects on one side of the earcups, which gives them a greater range of motion but also slightly weakens the build.
- 100% Avg.Temp.Difference
The JBL E50BT have an above-average sound quality that provides a punchy bass but slightly underwhelming instruments and vocals. The high tones are not too sharp, and they have a good amount of low end, which should please fans of bass. They also have a decent Soundstage. However, there's a dip in the mid-range that removes some of the warmth in the audio reproduction. It's not a deal-breaker for most, but they might not sound balanced enough for very critical listeners.
Good Bass Range performance. Low-bass and bass are over-emphasized by about 5dB, which makes the sound a bit bass-heavy. High-bass, on the other hand, is less emphasized and more neutral than the lower frequencies.
Decent Mid Range performance. Low-mid has a 6dB dip centering around 400Hz. This tends to thin out vocals/leads and decrease the overall warmth of the sound. The rest of the Mid Range is quite consistent and balanced.
Average Treble Range performance. Low-treble is quite balanced and consistent, except for the negligible narrow dip around 4KHz. In Treble, there is 5dB dip surrounding 6KHz which will have negative effects on presence and detail of vocals/leads. The bump in the high parts of Treble indicates a bit of sibilance and harshness to the high frequencies.
- 100% Avg. Std. Deviation
Average Soundstage. Despite the small opening on the drivers of these headphones, the PRTF score is decent. They also score about average in openness, which means these headphones won't sound as closed as noise-cancelling headphones, but not as open and immersive as open-back headphones either.
Average Imaging. There is significant amount of phase shift throughout the range, however, most of the shift is broadband and therefore less audible. The phase shift and mismatch in high-treble though, will have detrimental effects on the Imaging of these headphones.
Good Harmonic Distortion performance. The amount of harmonic distortion in the Bass Range is quite elevated, however, harmonic distortion in the lower frequencies are less noticeable. The amount of harmonic distortion in the rest of the range is good, even at higher volumes.
These headphones deliver a subpar isolation performance. They only block noise through the passive isolation the ear cups provide. Unfortunately, due to their awkward fit, they don't prevent noise from seeping into your audio or from leaking and potentially distracting the people around you. They won't be the ideal headphones for loud, noisy commutes or long flights, and they may be a bit too noisy to use in a library or other quiet environments.
Poor isolation. Due to the passive isolation and poor fit, these headphones fail to achieve any isolation in the Bass Range. The amount of isolation achieved in the Mid and Treble Ranges are also sub-par.
Poor Leakage. The large drivers and poor seal of these headphones cause them to leak a lot. The majority of the leakage is between 800Hz and 5Khz, with a sharp peak in loudness at 1.5KHz.
The E50BT have an excellent wireless range but quite a bit of latency for watching videos. It shouldn't be an issue when streaming audio but they won't be the ideal headphones for gaming or watching movies. They also do not have an app to control the active features or enhance sound. On the upside, they have an above-average battery life.
The E50BT have a great wireless range. They rarely dropped any audio either indoors and outdoors. They even maintained a stable connection slightly above 50ft when the Bluetooth source was placed in another room. This makes them a good pair of wireless headphones to use around the house or at the office. However, they have the typical hold-to-pair procedure and no NFC so it might get a little tedious to switch between Bluetooth devices.
The JBL E50BT have an average battery life. They last around 20 hours which makes them decent headphones to use on a long flight or a road trip. Unfortunately, there is no auto-off timer so if you leave them on they will run out of battery. You also can't use them while they're charging as the power and audio cables share the same port.
No compatible app.
