ISN Audio NEO 5

The Neo5 deliver a bouncy, energetic L-shaped sound with superb dynamics and epic amounts of bass. The Neo5s are all about the bass - it will grab your attention through sheer volume, but the rest of the frequency spectrum feels impressively unaffected. It is unashamedly elevated far beyond neutral, and despite not being the fastest I've heard is definitely not the slowest - this isn't bass that struggles to catch up with the rest of the music, nor is there any lack of cohesion because one driver is working out of sync with the others. Dynamics are superb, which is a real strength of the Neo5s - this is a quality I value extremely highly.

Bought this after watching reviews from Akros and Tonedeafmonk and wasn't disappointed. SOUND: Luscious bass, warm lower mids, slightly recessed mids, nicely balanced upper mids and highs with enough energy to satisfy but well below the level where I'd find them fatiguing. Great for classic rock, electronic, and metal (with the exception technical metal where something leaner/faster would be better). FIT: Absolutely no complaints on the fit.
AESTHETICS: I love the purple faceplates and shells but don't mind the ISN logo nor the font they used for NEO 5. ACCESSORIES: Nice cable, good tips, and a pocketable case. OVERALL: While not my daily drivers, they are a very enjoyable pair that I listen to when I'm in the mood to kick back and submerge myself in a high quality "guilty pleasure" type sound signature.

While I can't call the Neo5 master of technicalities, it's lush tone and addictive bass and vocal make it very easy to love. This is the kind of IEM that make time pass without we notice it because it's easy to get lost in it's cozzy and dynamic musicality.
It might be a bit of guilty pleasure, but the fact its so well balanced and sirupy as a whole tend to not make me ashame of loving the Neo 5.
These will please both basshead and vocal lover, as well, those who are afraid of balanced armature metallic timbre can be relieve: here it's creamy, euphonic and natural tone, and it doesn't sound thin at all: everything is thick and full in body with the Neo5.

The Neo 5 is a brand new approach to sound design. Showcasing a frequency range placement new to the world of IEMs. Here we are met with heavy bass, but the mids and top end are dovetailed together to form the most beautiful example of simplicity. the separation into the stage, the fast attack and transient abilities, the finite focus of energies into perception of imaging, added V shape resulting from slightly more bass energy. it’s a slightly new style of tune for ISN to come-up with. The Neo 5 is absolutely one of the best fitting IEMs I have ever come across.
