Sennheiser IE 100 PRO Wireless Monitoring Earphone - Black with built-in mic for your mobile phone, PC or tablet. Passive noise cancelling & 10hours battery life

Sound quality: neutral sound, a bit on higher side. Low is very good and clear. Sound signature is really of my taste. Crystal clear, crisp, on point sound. Most noticeable attribute is sound stage. Very wide spacious sound stage. Build quality: very comfortable and light. Best fit in ear. But feels delicate specially on the point of connectors. Connector: the connector is not typical ‘MMCX’ type. It is Sennheiser exclusive connector. This is the only drawback i have found. A universal connector helps in having choices over buying different quality and of different length of cable. Though the cable quality is very good. Soft and durable. Bluetooth connector: Bluetooth connector is just for casual listening. I noticed a huge difference in sound stage while shifting from wired to Bluetooth connector. With Bluetooth connector it sounds just like any other Bluetooth earbuds half the price. So I never use Bluetooth. It is just for ‘just in case’ type of purpose. Overall I found it to be really good sounding and best fit among all other earphones in my collection. I have bought it in 8.7k with Bluetooth adapter which is a great deal. ** The wireless version is not just wireless. It comes with both 'Bluetooth adapter' and '3.5mm cable'. So wireless version is basically the wired version along with an additional Bluetooth adapter. See the box contains in my uploaded picture.

This is definitely the worst tech purchase I’ve made in a while. For a brand like Sennheiser and a ₹10,000 price tag, I expected significantly better quality across the board. Sound & Build: The sound quality is just okay—there is absolutely nothing extraordinary about it that justifies the cost. Worse, the construction feels incredibly cheap and plasticky, completely lacking any premium feel. The Dealbreaker (Bluetooth & Mic): The absolute worst part of this package is the Bluetooth adapter. The call quality is practically unusable; it's nearly impossible to hear anything meaningful on the other end. To make matters worse, the microphone seems to pick up every single ambient sound in the room except your actual voice. Battery Life: Rounding out the flaws is the terrible battery life on the wireless module, which drains far too quickly for reliable daily use. Verdict: I strongly advise against buying this. It’s severely overpriced for the poor experience it delivers. I wouldn't recommend this to anyone.

There are few issue I have observed: BT connector not giving loudness as compared to wired BT connector has shorten size of cable, which make too difficult to access multimedia keys. Due to shorten length in BT, there are high chance that it can fell off while riding It does not supports LDAC at current price

Good

Keep saying volume max on iphones when typing. Very irritating. Other than that mic is awful never picks up voice even for phone calls or skype calls.

I recently acquired the Sennheiser IE 100 Pro, and while I’m pleased with its sound quality, I find myself grappling with build quality issues. Here’s a breakdown of my experience: Sound Quality: The IE 100 Pro lives up to Sennheiser’s reputation. Its sound signature is impressive, with clear trebles and a well-defined bass. I appreciate the balanced audio output and minimal distortion. Build Quality Concerns: Unfortunately, the build quality leaves much to be desired. The cable is prone to flaking and fraying, which is frustrating. Moreover, sourcing a replacement cable in India is challenging. Unlike standard MMCX connectors, the IE 100 Pro uses a proprietary cable, limiting our options for replacements. Longevity Worries: When I invested in these earphones, I expected them to withstand regular use. After all, the convenience of not discarding a good pair of earphones when the battery dies was a significant selling point. However, the wire didn’t even survive a year before showing signs of wear. Warranty Process: I’ve initiated a warranty claim for my IE 100 Pro, but I’m concerned about the long-term scenario. If the wire fails again after another year, I’ll be out of warranty and facing the same predicament. Déjà Vu with IE 400 Pro: Interestingly, my experience with the IE 400 Pro mirrors this situation. The wires on that model also suffer from fraying and flaking at the joints. In summary, while the IE 100 Pro delivers exceptional sound, its build quality falls short. Sennheiser should address these issues promptly to ensure a more durable product for its discerning customers.

earfones are really good from every aspect, but only problem im am facing is , i have downloded the App Name Smart Control, and i am not able to connect or Add my device in an App., Its just Denying every time i try to Add. Dont know what to do about it, Reinstalled 2 Times the App, Please suggest if anyone knows the solution. Thanks.

Ich habe mich schon an deutlich teureren In-Ears abgearbeitet, die mich letztlich immer enttäuscht haben. Die Pro IE 100 Pro haben mich hingegen vom Sound und Tragekomfort überzeugt. Ich nutze sie auch gerne beim Radfahren. Abzug gibt es für die wenig intuitive Bedienung und die fehlende App. Es gibt keine Anzeige oder Abfrage für den Ladezustand, sondern nur eine Warnmeldung, bevor kurz danach Schluss ist.

What I liked about these is that you have the option to go wired or wireless which gives the best of both worlds. The sound quality is good for what I use it for (mostly music, podcasts) and they are pretty good at noise cancelling to an extent. It seems like the trend is going towards Bluetooth headphones so having the option to go wired is nice.

Toller sound

Prodotto eccellente.Utilizzate con Xiaomi 17 Ultra. Il volume bluetooth è più basso rispetto al collegamento via cavo con PIN jack che al contrario è troppo esagerato... Quello che posso consigliare è di indossarle bene perché è un attimo fare confusione tra le orecchie....e poi il suono sarebbe da cuffiette da pochi euro....Al contrario indossate perfettamente aderiscono al padiglione auricolare e da lì in poi piano con il volume....Bassi superbi.... Ripeto Eccellenti

Excellent sound quality. You can here a lot of detail in each song.
