Sennheiser Professional Audio IE 100 PRO Wireless Monitoring In Ear Earphone – Red with Built-in mic for Your Mobile Phone, PC or Tablet. Passive…

Tried the BT module, definitely not enough amps for me so its too quiet. It’s also rather awkward to wear around the neck and it dangles off my ears making me feel like Jar Jar from Star Wars. Not a good look.

The IEM themselves are great and can’t recommended them enough for the quality and price. Nice sound isolation with the ear cones too.

I’m writing this review again because my first 3☆ review got deleted by either Amaz0n or S3ller, maybe because I used bad word or said too much?
So this time I’ll make this review simple & writing it after 2 months usage.

first let me makes you understand meaning of Audiophile or what audience these IEMs are for.

IEMs are for those who love to listen original Natural sounds Music coming out of Studios & we call them Audiophiles or for those who work at Audio Studios & create Music without boosting any level of any Instrument they recorded in big Halls or Operas.

as for us Music lovers who only love to listen bassheads, Rock or some of us do love Natural sound music but also want some punchiness & little boost increase in bass? so let me tell you these IEMs aren’t for us, we’re good with our 800 – 5k Earphones like old Sennheiser CX series & other brands’ good earphones.

as I said in Title “not for Punchy, Bass & Bollywood style Music lovers”
it because this IEM has not Punchy type feelings nor good Bass like your old CX 180 or CX 275s have, of course it does have far better instrumental sound quality but it still feels behind in Female & Male voice performance when you listen Music or in simple words this IEM do focus more on Instruments than singers’ voice, which won’t makes your body dance by it’s own like Magical sounds of old CX series(don’t go for current new series) used to do with their Balanced sound between both singer voice & instruments with punchy bass when they were in stocks plus they were far more cheaper in price than these one.

still I could recommend you these IEM only if it’s price started from 7k instead of 10 or 13k for Bluetooth version(it because it’s range is really low like under two rooms & if you go any far you’ll get lag also sounds low too compared to Wired version) & 5.8k for only Wired verison(because wired version has lesser bass than it’s Wireless version, also if you’ll increase your volume over 80% you’ll get near no Bass & for optional con is No Mic because as I said IEMs for Studio work only Not for vacation or outdoors).

so in short
if you’re Natural Music listeners without caring about Bass then go for these IEMs

if you’re like me who love Natural & balanced punchy Bass Music(for ex: CX 180 & 275s) then you shouldn’t go for these IEM, also stay away every type of IEMs

&
if you’re one of those who do wanna try IEM for first time but also limit with budget then I’ll suggest you go for those under 3k Chinese IEMs instead of wasting 10k so you won’t had to regret later as I’m regretting.

(Suggestion for Sennh3is3r company please reduce the size of Medium size buds they kinda uncomfy & also please bring back Old CX Series otherwise New CX Series only creating E-Waste in Amaz0n as you can see how many Renewed version of current CX Series about to touch Fresh version, also it’s hurts us Fans’ hearts too, so please bring Old CX series back🙏)

Es un producto caro, pero vale mucho la pena por su dualidad de alambrico e inalambrico

A pesar de ser de precio elevado, el sonido y la calidad del audio es superior a cualquier producto de la competencia dentro de la gama(gama de entrada). El módulo bt es una buena solución para escuchar secuencias y metrónomo para gigs pequeños y funciona súper bien. Comparado con Shure o KZ es sin duda una muy buena inversión en esta gama de productos.
Actualización: El auricular izquierdo ya no funciona…Casi no los usaba para trabajar en su mayoría eran ensayos y con el módulo BT me era suficiente. Así que el cable lo usé aproximadamente una vez por mes. A la fecha no más de 10 ocasiones. Primero el auricular izquierdo comenzó con un falso contacto. Y después de dos o tres cambios más dejo de escucharse. Se que es el auricular por qué he probado el auricular derecho con las diferentes entradas tanto del módulo como del cable y sigue funcionando perfectamente.

I was so disappointed in these, I returned them. Volume left way too much to be desired especially for the price, so I returned them.
