Sennheiser IE 100 Pro Wireless review: Excellent for work and play

Sennheiser-IE-100-Pro-Wireless review

Sennheiser recently launched a wonderful pair of Bluetooth headphones in the market that are built for both professional and music lovers. We spent some time with the Sennheiser IE 100 Pro Wireless Bluetooth earphones to find out what they are all about. This is the Sennheiser IE 100 Pro Wireless review you all have been waiting for.

Sennheiser IE 100 Pro Wireless review: Design

Sennheiser has always been good with its packaging. As soon as you cut open the seal and pull the cardboard tray out of the box you get to see the shiny Sennheiser IE 100 Pro Wireless BT earphones that are tucked in a nice foam encloser. The box also has a 3.5mm auxiliary wire (in case you run out of battery juice) and a USB Type-C charging cable with a small carry case, which reminded us of a similar spectacle case our grandmother used to use.

Moving on, the Sennheiser IE 100 Pro Wireless earphones are designed to perfection. They do look like the Sennheiser IE 300 earphones we reviewed recently, but they have a distinct personality. The basic shape of the earphone is the same, however, the enclosure is opaque. You can see the machinery inside. Also, a wire with the battery enclosure on one side and volume with power controls on the other side connects the two.

The Sennheiser IE 100 Pro Wireless earphones fit very nicely in the ear cavity and the adjustable wire end goes behind the ear. With that 2 additional pairs of ear tips are provided in the box (small and large). Overall, the look and design of the audio earphones is very nice, everything about them screams style

Sennheiser IE 100 Pro Wireless review: Performance

Let’s quickly talk about the tech specs of the Sennheiser IE 100 Pro Wireless earphones before we talk about our audio experience with them. This nifty gadget comes with 2 years of warranty, works with any Bluetooth 5.0 driven device, and supports AptX, AAC and SBC codecs. The frequency response is between 20Hz to 18kHz, and the impedance is set at 20 Ohm. The audio neckband also has a microphone for you to make and receive calls.

We used them in a couple of Zoom calls on the PC and took it out for a run. Both times we were very impressed. The sound quality is far superior to any BT neckband we have used in recent times. The audio calls were clear and other party could hear us well too. The same is when you listen to music, the bass is perfect and high and lows are very audible. No matter what genre of music we threw at the Sennheiser IE 100 Pro Wireless audio earplugs, Jazz, rocks, EDM, Bollywood et al, they just managed to bring out the best.

Battery life is not bad either. The company claims these can last for 10 hours when fully charges, but we got about 8.5 hours out of them. To fully charge them using the supplied USB Type-C cable it took about 1.5 hours, which some might feel is a bit high, but we suggest you can put them to charge when you wake up and take them with you when you are leaving the house, this way you will get you workday battery life. In case you run out of it, Sennheiser has supplied the users with a 3.5mm aux cable in the box.


All in all, we quite liked the Sennheiser IE 100 Pro Wireless earphones. They sound great, they look good, and they never fell out even when we went for a run with them. At Rs 9,899 (Amazon price) these are an extremely good pair of earphones that cancel noise passively and provide superior sound quality.


Excellent sound quality

Good built

Long battery life



Some might find it a bit costly
