Sennheiser NP 02 On-ear neckband headphones, Box of 20

Product Overview

The Sennheiser NP 02 is a lightweight, on-ear neckband headphone designed for distribution to audience members in assistive listening environments such as infrared (IR) hearing assistance and induction loop systems. Its over-the-neck neckband design is ideal for venues where listeners may be wearing hats, headgear, or hearing aids, ensuring a comfortable, secure fit without pressing against the top of the head. Sold in a box of 20 units, the NP 02 gives venues, houses of worship, auditoriums, and government facilities a cost-effective, hygienic solution for large-scale assistive listening programs. The easily changeable ear pads make between-user sanitization fast and practical.

Product Description

Unlike conventional over-ear or on-ear headphones that rest on a headband above the head, the NP 02 uses an ergonomic neckband that wraps around the back of the neck and positions the ear cups from below. This makes the NP 02 particularly well-suited for audiences who wear religious head coverings, hard hats, medical headgear, or hearing aids, as there is no top-mounted band to interfere with existing headwear.

Audio quality is optimized for speech intelligibility rather than wide-frequency music reproduction, making the NP 02 the right choice for sermon clarity in houses of worship, speaker amplification in council chambers, and proceedings intelligibility in courtrooms and public hearing rooms. The 32-ohm impedance and 20–20,000 Hz frequency response ensure compatibility with the full range of Sennheiser IR assistive listening receivers including the SI 1015 and SR 2020 series, as well as induction loop and personal amplifier systems from other manufacturers.

The single-sided cable eliminates tangling and keeps the listening experience tidy and discreet for audience members. The NP 02 is available in two cable variants: the NP 02-100 with a 100 cm (39 in.) straight 3.5 mm stereo plug, and the NP 02-140 with a 140 cm (55 in.) 90° angled 3.5 mm stereo plug. Both variants are included in this box of 20 listing — select your preferred cable configuration at checkout. Replacement ear pads are available separately, supporting long-term deployment across many events and seasons.

Frequently Asked Questions

Q: What is the difference between the NP 02-100 and NP 02-140?

The NP 02-100 has a 100 cm (39 in.) cable with a straight 3.5 mm stereo plug, while the NP 02-140 has a 140 cm (55 in.) cable with a 90° angled plug. Both are functionally identical; the angled plug is preferred when inserting into a pocket-worn receiver to reduce cable strain.

Q: Why use a neckband headphone instead of a standard headband headphone for assistive listening?

The neckband design avoids pressing against the top of the head, making the NP 02 comfortable for users wearing hats, religious headgear, hard hats, or hearing aids. It is ideal for diverse public audiences where headwear is common.

Q: Are the ear pads replaceable?

Yes. The NP 02 features easily changeable ear pads that can be swapped without tools, supporting hygiene protocols when the headphones are shared between multiple audience members across events.

Q: Is the NP 02 compatible with Sennheiser IR assistive listening systems?

Yes. The NP 02 is designed to work with Sennheiser’s infrared assistive listening receivers including the SI 1015 and SR 2020 series, as well as compatible third-party IR and induction loop receivers using a standard 3.5 mm stereo output.

Q: How many headphones are included in the box?

Each order includes a box of 20 NP 02 headphones. This makes it a practical choice for venues equipping an entire seating section or compliance kit for hearing-impaired guests.

Q: Is the NP 02 suitable for music listening, or only speech?

While the full 20–20,000 Hz frequency response technically supports music playback, the NP 02 is optimized for speech intelligibility in assistive listening contexts. It is not intended as a consumer or studio music headphone.

Q: Can the headphones be cleaned between uses?

Yes. The removable ear pads are the primary contact surface and can be cleaned or replaced between users. The headphone body can be wiped down with a damp cloth. Always allow headphones to air dry before reuse.

Q: What receiver systems is the NP 02 compatible with?

The NP 02 is compatible with any assistive listening receiver with a 3.5 mm stereo headphone output, including Sennheiser’s SI 1015 IR receiver, SR 2020 receiver, induction loop amplifiers, and FM/RF personal amplifier systems.
