The JBL E55BT are stylish-looking headphones with an above-average sound and a comfortable design. They're lightweight yet decently well-built and they're pretty easy-to-use. They do well for most use cases but do not block enough noise for very noisy environments and won't be the best headphones for watching movies or gaming.
- Comfortable and lightweight design.
- Above-average sound quality.
- Poor noise isolation.
- Inconsistent bass.
The JBL E55BT headphones have a simple and straightforward design. They come in a couple of color variations to match your preferences and tastes. They're also quite comfortable and lightweight so you can keep them on for hours without much fatigue. They do, however, make your ears a little hot after a while, and although decently well-built they look and feel a bit cheap once in your hands. On the upside, they're decently portable, easy-to-use, and stable enough to exercise with.
The JBL E55BT have a simple design and clean look. They have a relatively thin headband and decently sized oval ear cups that are well padded and relatively well-built. They have a few color schemes that stand out, like the red version we reviewed, but there's also a more understated all-black variation that some may prefer. The ear cups protrude a bit once on your ears and the buttons on the right ear cup look and feel a bit plasticky, but overall they're a stylish looking headphone that should work for most.
The JBL E55BT are comfortable headphones. They have decently sized ear cups that fit well around most ears. They're lightweight and do not put much pressure on your head. However, the ear cup padding is a little stiff which is most noticeable after long listening sessions. They will get a bit fatiguing after wearing them for a while.
The controls scheme on the JBL E55BT headphones is simple and efficient. You can skip tracks, play/pause audio, and control the volume with their easy-to-use three buttons set up. They also have an additional button to enable the Bluetooth pairing mode. The control scheme is responsive but the buttons feel a little cheaply made.
The JBL E55BT fold into a more compact format which makes them decently portable. They're still somewhat cumbersome to carry around on your person since they won't fit in any pockets and do not come with a case. But compared to other over-ear headphones they're pretty small.
The JBL E55BT have an above-average build quality, but slightly cheap and plasticky ear cups. The headband is decently flexible and has a thin metal frame that makes it sturdy enough for repeated use or accidental drops. The ear cups are also decently dense and won't get damaged if the headphones fall once or twice, but the quality of plastic used in their build feels cheap. This is most noticeable with the buttons on the right ear cup. They're a sturdy headset they just don't feel as durable as some cheaper options like the Bluedio T4.
The JBL E55BT is an above-average sounding pair of closed-back over-ear headphones. They have a deep and powerful bass, a balanced mid-range, and a neutral treble. However, the bass is slightly hyped and prone to inconsistencies, their mid-range is a bit recessed, and their treble could lack some detail. Additionally, they don't have an open and spacious soundstage.
Great bass range performance in our JBL E55BT review. Low-frequency extension is at 10Hz, which is excellent. Low-bass and mid-bass are quite flat but overemphasized by more than 3dB. This adds a bit of excess kick and thump to the sound, without making it too muddy, thanks to the less overemphasized high-bass.
Great mid-range performance. Low-mid has a 4dB dip centering around 300Hz, which thins out the vocals a little bit. However, the rest of the mid-range is virtually flat and flawless.
Very good treble range performance. The only remark here is the relatively broad 5dB dip centered around 5KHz, which negatively affects the presence and detail in vocals/leads.
Sub-par frequency response consistency. The consistency in the treble range is very good. However, in the bass range, there could be as much as 18dB of variance at 20Hz across multiple users. We also noticed having glasses on could break the seal the JBL E55BT and cause a drop in bass.
Sub-par soundstage performance. Due to the relatively shallow cups, as well as the closed-back design, these headphones don't produce a speaker-like soundstage.
Mediocre imaging performance. Phase error is relatively high, especially in the lower frequencies. Additionally, the L/R drivers of our test unit showed more than 27 degrees of phase mismatch, which could skew the stereo image a little bit.
Average harmonic distortion performance. At 90dB SPL, the overall amount of THD is low and within good limits. At higher volumes, however, there is a noticeable rise in distortion the bass range and around 5KHz which could make the treble sound a bit harsh.
The JBL E55BT only passively isolate against ambient noise. They create a decent seal around your ears that blocks some high-frequency noise from seeping into your audio. However, in most cases, they won't isolate enough for loud, noisy environments like those involved in commuting and traveling. You can mask some of the noise if you play your music at higher volumes but the headphones will leak a little and may distract those around you.
Poor isolation. These headphones don't have active noise cancelling and isolate only using their ear cups. In the bass range, they achieve no isolation, and in the mid-range, they achieve only 7dB of reduction which is sub-par. In the treble range, however, they isolate by more than 28dB, which is above average.
Mediocre leakage performance. The significant portion of leakage sits between 500Hz and 4KHz, which is a relatively broad range and concentrated in the mid-range. The overall level of leakage is not very loud though.
Mediocre microphone performance. Speech recorded with the JBL E55BT will sound relatively thin and noticeably muffled, and this will have a negative effect on speech intelligibility. They also don't have great noise handling, making them unsuitable for moderately loud environments like a busy street.
Mediocre recording quality. LFE is at 280Hz, and HFE is at 3.5KHz. This makes recorded speech to sound relatively thin and muffled. The region between LFE and HFE is also relatively inconsistent, which is not good.

Mediocre noise handling. The E55BT is not able to separate speech from ambient noise effectively, and only achieves about 11dB of speech-to-noise ratio.
The JBL E55BT have an above-average wireless range and a good battery life but won't be ideal for watching movies. They have about 185ms of latency which shouldn't be an issue when streaming audio but won't be suitable for gaming. They also do not support the JBL Headphones app which makes them less customizable than the Everest Elite 700 and also means they do not have an adjustable auto-off timer, which is a bit disappointing.
The JBL E55bt have an above-average wireless range. They reached up to 37ft when the Bluetooth source was obstructed by walls and almost 119ft in direct line-of-sight. Unfortunately, they don't have NFC for easy pairing but the dedicated Bluetooth sync button is pretty easy-to-use.
The E55BT won't be ideal for watching video content. They perform about as well as most Bluetooth headphones with no low latency codecs.
These headphones have an above-average battery life and decent charge time. They do not have an auto-off timer like the Everest Elite 700, but have passive playback, and you can use them while they charge which makes them decent office headphones if you don't mind having the USB cable plugged into your PC.
