Raycon E100 Truly Wireless Headphones Review

The Raycon E100 have a fairly circular design. They have a big button with Raycon’s logo and a sporty look thanks to the stability fins. They don’t protrude too much out of the ear and don’t stand out too much. They come in black, white, or blue.

The Raycon E100 have a typical in-ear fit that isn’t the most comfortable. On the upside, they come with five other tip options and a different-sized stability fin to help you find the best fit for you. If you usually find that in-ears aren't comfortable, you'll have the same issues with these headphones. For slightly more comfortable in-ears, check out the Raycon E55 Truly Wireless or the smaller Raycon E25 True Wireless.

The Raycon E100's control scheme is okay. You get most expected controls like play/pausing music, track skipping, volume controls, and taking calls. However, it’s not the most intuitive, as raising or lowering the volume is done with triple taps, which is annoying if you're looking to change your volume quite a bit. You can also trigger your voice assistant easily. The buttons are clicker than the Raycon E50 Truly Wireless but don’t offer any audio feedback.

Like most in-ears, these headphones don’t trap heat around or in the ear. They won’t make you sweat more than usual when working out, so they're a good option for sports.

These truly wireless headphones are very compact. The two buds take up very minimal space and can easily fit in pockets or a bag.

The Raycon E100 come with a nice hard charging case. The headphones are protected against scratches, minor water exposure, and physical damage from falls. The case feels very well-made but isn’t on par with the premium feel of the Sennheiser Momentum True Wireless or the Bang & Olufsen Beoplay E8 2.0 Truly Wireless 2019. On the upside, it has four lights that give you battery information.

The Raycon E100 are better built than the Raycon E50 Truly Wireless. The materials used feel more durable, and they're also rated IPX7 for water resistance. They feel robust and dense, meaning they should survive accidental falls without too much damage.

The Raycon E100 are stable enough for sports. Their stability fin design helps get a secure fit, and head movement doesn’t make them move around. However, since they provide a very air-tight seal, popping the seal might make them wobble around in your ear, and it'll be frustrating to replace if it happens often.

Thanks to their in-ear fit, the Raycon E100 have fantastic frequency response consistency. This means users will have a very similar audio reproduction when using these headphones.

The Raycon E100's bass performance is great. Although the response is slightly over our target curve, it's well-balanced and flat. This means that these headphones will produce great bass with a bit of extra thump and punch. Some people may prefer this, especially if you listen to a lot of bass-heavy music.

The Raycon E100 have a very good mid-range performance. There's a noticeable tilt favoring lower frequencies, making the vocals and lead instruments sound a bit cluttered. The dip in the mid-range will also push them to the back of the mix. These headphones won’t be the best option for vocal-centric music.

The Raycon E100's treble performance is okay. It lacks detail and brightness in the low-treble, which will mainly affect vocals and instruments. On the other hand, the response is noticeably over our target curve in the mid-treble, resulting in sharp and piercing sibilants (S and T sounds).

The Raycon E100's stereo imaging is incredible. The graph shows that the group delay is under the audibility threshold, resulting in tight bass and treble ranges. Also, the L/R drivers of our unit were very well-matched, which is important for the accurate placement and localization of objects (voices, instruments, video game effects) in the stereo image. Note that these results are only valid for our unit, and yours may perform differently.

The soundstage is bad. This is because creating an out-of-head and speaker-like soundstage is largely dependent on activating the resonances of the pinna. The design of in-ears and earbuds fully bypasses the pinna and doesn't interact with it. Also, because these headphones have a closed-back enclosure, their soundstage won't be perceived to be as open as that of open-back earbuds like the Apple AirPods (2nd generation) Truly Wireless, or the Bose SoundSport Free Truly Wireless.

The Raycon E100's noise isolation performance is great. It does a decent job at blocking out bass frequencies like the deep rumble of a bus or plane engine, which makes them a good option for commuting. You can use them in an office setting as they do a very good job at isolating against work environment noise like ambient chatter and A/C systems.

The Raycon E100's leakage performance is incredible. These in-ear headphones barely leak, so you won’t have to worry about disturbing surrounding people with your music. However, blasting your music at very high volumes in completely quiet environments might be audible to some.

The recording quality of the Raycon E100's integrated microphone is sub-par. It sounds muffled and noticeably lacks detail. Recorded speech is understandable in very quiet environments, but the quality isn’t good.

The Raycon E100’s integrated microphone's noise handling performance is sub-par. The mic has trouble separating ambient noise and recorded speech. People on the other line can have trouble understanding you in moderately loud situations like walking on a busy street. These headphones are better-suited for very quiet environments.

Their battery life is okay. They only provide about 3 1/2 hours of continuous playback time. They have a very similar battery performance to the Raycon E50 Truly Wireless. Similarly, they have an auto-off timer that is very useful as the headphones don’t necessarily power off when put in the case. If you forget to turn them off manually, you can play content even in their case. On the upside, the case holds about four extra charges, according to the manufacturer.

There's no dedicated companion app for the Raycon E100.

The Raycon E100 are Bluetooth 5.0 compatible, which means you might get better overall performance if your source supports it too. However, you can't pair it using NFC, although their pairing procedure was noticeably easier than the E50, which is nice. They also can only be connected to one device at a time.

Like the Raycon E50 Truly Wireless, the Raycon E100 have high latency with iOS and Android devices as well as PCs. This won’t be ideal for watching video content, as some people may notice a delay with audio. However, some devices and apps offer some compensation, so you might not notice it as much.

As expected, you can't use these truly wireless headphones wired.

The Raycon E100 come with a hard charging case that serves as a charging station for your headphones wherever you are. It holds about four extra battery charges, according to the specs sheet.
