What is a B-stock product?

A product becomes B-stock when it can no longer be sold as new. It can simply be a product that has been returned by a customer or it may have packaging that is damaged or missing. It’s possible that the product itself may show slight signs of use or damage too. All B-stock products are fully checked to ensure that they work properly and you can find details of why the product is a B-stock in the information above.

Product information

General

Fitted with a Bluetooth module, the Sennheiser IE 100 PRO Wireless in-ears set you up with a tight set of heapdhones for casual listening and phone calls, and web-casts, alongside professional on-stage monitoring. Essentially a two-in-one bundle, this pack comes including the Sennheiser IE 100 PRO in-ear monitors, the Sennheiser IE PRO BT neck-cable complete with smartphone remote controls and integrated microphone, and for a more old-school set up, a standard headphone cable.

Stage Sound On-The-Road

The Sennheiser IE 100 PRO in-ears offer tight on-stage monitoring backed up by dynamic audio, a consistent frequency response at both low and high volumes, and snug, secure comfort. The newly-designed 10mm driver produces a precise reproduction of the stage acoustics during performances, resulting in exactly the kind of warm yet powerful and detailed monitor sound demanded of live gigs, no matter how loud it gets. These pro-grade in-ears can even double as casual listening headphones.

Compact, Comfortable & Powerful

Since the level of comfort needs to match the sound-quality, the IE 100 PROs come finished with ergonomically constructed ear-buds with a tight and secure feel, limiting listening fatigue whether Dj-ing or playing bass. To keep your in-ears in peak condition, Sennheiser have included a soft protective soft-bag, a cleaning tool, and a selection of ear-buds made of both foam and silicon and in various sizes for the perfect fit.

Sennheiser IE 100 PRO Wireless Black Live In-Ear Monitors

The headphones fit well in the ears when using the silicone ear tips. The sound is clean and rich, although for my taste they could use a little more bass.

Keep in mind that they play at a lower volume over Bluetooth. However, when connected with the 3.5 mm cable, they really open up and perform at their full potential.

The Bluetooth adapter is not very convenient to use. The cable is too short, and the plastic modules tend to move around while walking or moving. On the iPhone, the voice assistant works properly.

The carrying case included in the package feels a bit too small for storing the headphones together with the Bluetooth module.

I mainly bought these headphones because of the Bluetooth module.
