The Shure SE425 earphones are a relatively high-end product from the Illinois, US-based company. They sit approximately in the middle of the SE range, which includes the following models: SE112, SE215, SE315, SE425, SE535 and SE846. See our review of the SE215 here. The SE425s come in at $299, so they are not for the light of wallet. The earphones are not hyped to appeal to a certain genre. They are aimed at audiophiles or musicians who want balanced reproduction. The design is inspired by on-stage monitor technology and as such the earphones can be used as monitors or for personal use. They are available in clear (SE425-CL) and metallic silver (SE425-V).

Shure SE425 an update on the SE420 model

The Shure SE425s are an update on the older SE420 model. The older earphones had a more traditional design which stuck out from the ear, while the SE425s sit snuggly within the curve of the ear. For a model intended for use on stage, it seems a logical move. It would also benefit casual music listeners, reducing the likelihood of the earphones being displaced from the ear or producing wind noise.

Dual driver design

The earphones feature dual high-definition microdrivers, with a dedicated tweeter and woofer. They offer clarity and balanced reproduction with the frequency range being 20Hz-19kHz. These earphones will reveal subtle elements within familiar recordings which you have not heard before on other set-ups. They are not hyped or bass heavy. In fact, fans of electronic music may find the bass underwhelming. If you are looking for a heavily-tailored sound, these are not the earphones for you. However, their balanced sound does mean that they will produce good results across a range of genres. The highs are rich, the mids detailed and the bass solid. The isolating design helps produce a satisfying bass reproduction.

Detachable cable set-up

The SE425s feature a detachable 64″ Kevlar reinforced Y-shaped cable, which terminates at the earpieces. This is the point at which many earphones fray and break. The detachable cables can swivel, allowing them to move freely and increasing comfort. At the other end of the cable, the 3.5mm jack is somewhat bulky, although it thins out at the end to accommodate a phone case. There is a two-year limited warranty, under which the cables may be replaced. If the issue falls outside of warranty, you can expect to front a $35 charge for a new cable. Naturally this is much less than a user would find themselves paying for a whole new set of earphones.

The earphones are intended to be worn with the cable run behind the head and wrapped around the top of the ear. There is a slider to reduce the length of the cable going to each ear. The end of each cable has been thickened and is mouldable to hold it in place. This has the advantage of making the earphone less likely to fall out or break its seal on the ear. The design is surely advantageous to those who want to use the earphone on stage, and also those who want to use it while moving about. It won’t please everyone however. The cable set-up can result in a noticeable pulling on the ear at times, which some users will find unpleasant. The appearance of the SE425s is no-nonsense and workmanlike. These are not a design for those who want to make a fashion statement.

Variety of sound-isolating sleeve options

The Shure SE425 earphones ship with a total of eight sound-isolating sleeves: Small, medium and large in both soft flex sleeves and foam sleeves, triple flange sleeves and universal fit yellow foam sleeves. The foam sleeves are intended to be compressed before placing them in the ear, allowing the foam to expand to provide a tight fit. The sleeves block up to 37 dB of ambient noise. The earphones provide strong noise isolation, suitable for a headphone designed for on-stage use. In addition to the sleeves, the earphones ship with a 1/4″ adapter and a hard carrying case.

The standard SE425 does not come with a remote. Shure offer two optional remote and mic designs: A three-button remote for iOS devices and a single-button set-up for other devices. The former allows you to adjust the volume, control music and video playback, record voice memos, and answer or end calls. The latter is that they allow you to answer or end calls and switch back to audio.

The Shure SE425 earphones are a somewhat pricey model and the quality matches the asking price. The reproduction is fairly flat and is suitable for professional applications. Lovers of bass-heavy music may want to look elsewhere for a more tailored response. The sound isolation is certainly strong enough for everyday use and is also suitable for on-stage use. If you don’t mind the over-the-ear cable design, then you will find plenty to love with the SE425s.
