| 7 mm Driver |
🎧 Joyroom JR-E103, a 7 mm driver earphone with metal housings and attractive design. We have reviewed other Joyroom Earphones like the Joyroom JR-E102, usually the brand has some pretty interesting designs. Inside the housings the Joyroom JR-E103 holds a small 7 mm dynamic driver and this allows them to have a super small housing size. Housings are nicely designed and metal constructed with also a very nice pearled coating finish, every detail of them is also made of the same metal as the housings and share the same colour and finish. By the way, if you are not attracted by pink do not worry because you can buy the Joyroom JR-E103 in either dark silver/gray, golden or pink. The cable is nicely built with a good tactile feel and anti-tangling capacity, inline there is a microphone and a practical and well made 3 button-control that is easy to use and provide the possibility to skip tracks, play/pause, answer/reject calls and set the volume up or down.

Accessories & Packaging
The packaging of the Joyroom JR-E103 is well built and nicely designed, it is very big and even more considering the tiny size of the earphone. Inside the package there are 3 pair of eartips, a cable clip and a soft leathery carrying pouch
Bass & Sub Bass
The Joyroom JR-E103’s 7 mm dynamic driver is able to provide enough punch and depth but it is not very strong, anyway their bass can cover any music genre bass requirements (probably not electronic, EDM music) Using an EQ, their mid-bass got punchier and the sub-bass deeper but overall somewhat boomy. During our extreme bass test while applying to the Joyroom JR-E103 a custom basshead EQ and amplifying them with a Fiio E12 amplifier, they were able to handle an impressive 48% of the Fiio’s maximum power responding with huge extra mid-bass punch and lot more of depth. Do not expect any basshead rumble or impact from them, something way below the KZ ATE and more inline with other microdrivers such as the Remax RM-565i or the UiiSii Hi-705.

Mids & Vocals
Mids of the Joyroom JR-E103 are warm, laid back with lower mids sound too distant and lacking energy of their lower vocals. Higher mids are not harsh and are less recessed than lower mids. With an EQ, lower mids sound less distant and overall their recession gets reduced but still lower vocals lack life while they sound boxy and higher mids get harshy.
Highs & Treble
Highs on the Joyroom JR-E103 are brightish with little to no detail but piercing highs and sibilance are not present. An EQ adds a good amount of extra brightness but still no detail, sibilance becomes mild and piercing highs are still not perceived.
Sound leaking from the Joyroom JR-E103 is low and very controlled, using moderate to medium volume levels their sound will not be perceived by nearby people in normally noisy situations. They could be usable as well in libraries if low volume levels are set.
Despite the tiny housings the Joyroom are very capable of isolating from surrounding noises, with medium volume they will partially block noises while applying high volume levels will provide a much more effective isolation.
The Joyroom JR-E103 are super light but well built with their metal housings, the ultra small size and 3-button control add to their great comfort and ease of use. Pain or discomfort is not something that you will feel with these earphones.
Response to Equalization
Their response to custom equalization is fair and can provide some improvement; highs are able to obtain more brightness but they do not gain any definition or detail, mids and vocals can remove some of their recession but boxy sound and harsh higher mids are introduced, bass gains punch and depth but get boomier too.
