Quick Answer: The best all-around hearing aid neckloop is the Williams Sound NKL 001 (about $60–$65), an 18-inch passive mono neckloop that plugs into any 3.5 mm headphone jack — phone, TV, laptop, MP3 player — and feeds a clean magnetic signal to any telecoil-equipped hearing aid. For everyday comfort and a breakaway safety clasp, the Bellman & Symfon Neckloop (about $40–$50) is the lighter-weight pick. If your main use case is phone calls specifically, the ClearSounds CLA7-V2 amplified neckloop adds up to 30 dB of its own gain so a weak phone signal still drives a strong loop. None of this works without a telecoil, though — and per The Hearing Review’s Consumer’s Guide to Hearing Aids, only about 59% of 2026 hearing aid models include one, down from 83% in 2017, so confirm yours has it before you order.
A neckloop is one of the cheapest, most overlooked accessories in hearing care — and also one of the most commonly bought by mistake, because buyers assume any hearing aid can use one. It can’t. A neckloop only talks to a telecoil, a small coil of wire inside certain hearing aids that reads a magnetic field instead of sound waves. If your hearing aid has one, a $50 neckloop turns any phone, TV, or looped venue into a direct, noise-free audio feed. If it doesn’t, the accessory does nothing at all. This guide covers the best neckloops on the market and, just as important, how to check compatibility before you buy.
Hearing aid neckloops by the numbers
- ~59% of 2026 hearing aid models include a manual telecoil as standard or an option, per The Hearing Review’s Consumer’s Guide to Hearing Aids — down from 83% of telecoil-capable devices in 2017. That decline is the single biggest reason to check compatibility before buying a neckloop.
- Popular OTC brands typically skip the telecoil entirely. Jabra Enhance, Lexie, Eargo, and MDHearing prioritize Bluetooth streaming and app control instead, so a neckloop bought for one of these devices usually goes unused.
- Table 219.3 of the 2010 ADA Standards for Accessible Design requires assembly venues — theaters, courtrooms, places of worship — to lend hearing-aid-compatible receivers, and at least 25% of those loaner units must include a neckloop for telecoil users, which is why owning your own is worth it if you attend looped venues often.

Best hearing aid neckloops
Williams Sound NKL 001 — Best Overall
Williams Sound NKL 001 Neckloop
- Plugs into any standard 3.5 mm headphone jack — phone, TV, laptop, MP3 player, or a venue's assistive-listening receiver — and converts that audio into a magnetic signal any telecoil can read.
- Marketed for moderate-to-severe hearing loss and sized for adult wear, with a lightweight rubber-coated cable designed for extended daily use.
- Williams Sound is the brand most assembly venues already use for their loaner ADA receivers, so a personal unit behaves the same way you're used to from a theater or lecture hall.
Confirm your hearing aid’s telecoil is switched on before your first use — try Amazon Prime free for 30 days so a neckloop this cheap arrives in two days instead of eating into a week of planning for a looped event.
Bellman & Symfon Neckloop — Best Lightweight / Everyday Wear
Bellman & Symfon Neckloop
- A lighter, thinner cord than the Williams Sound unit, built to sit comfortably under a collar for hours without feeling like extra hardware.
- Breakaway clasp releases under snag pressure — a genuine safety feature for anyone wearing it around small children, pets, or machinery.
- 3.5 mm connector pairs with the same range of sources: phones, MP3 players, TVs, and Bellman's own line of personal amplifiers.
ClearSounds CLA7-V2 — Best for Phone Calls
ClearSounds CLA7-V2 Amplified Neckloop
- Adds its own battery-powered amplification — up to roughly 30 dB of gain — which matters because a phone's headphone output alone is often too weak to drive a clean, strong loop signal.
- Built specifically for corded, cordless, and cell phone use, so it's the pick if phone calls are your main reason for wanting a neckloop rather than TV or venue loops.
- Reduces the buzzing interference some telecoil users get from cellular signals near a hearing aid, per the manufacturer's product notes.
Before you buy: confirm your telecoil
A neckloop is dead weight without a working telecoil on the other end. Three ways to check:
- Look up your hearing aid’s spec sheet for “telecoil,” “T-coil,” or “auto telecoil.” Manufacturers list it under connectivity or accessibility features.
- Ask your audiologist to confirm it’s programmed and switched on. Some hearing aids ship with a telecoil that isn’t activated in the initial fitting.
- Check the style first if you’re shopping new. Behind-the-ear (BTE) and receiver-in-canal (RIC) models from prescription brands are far more likely to carry a telecoil than compact in-the-canal or OTC designs — see our hearing aid styles guide for which form factors still have room for the component, and our telecoil guide for the full 2026 breakdown of which brands still include it.
Neckloop vs. Bluetooth streaming: do you need both?
They solve different problems. A Bluetooth-streaming hearing aid pairs directly with your own phone and TV — no accessory needed, and that covers most day-to-day listening for anyone with a modern device. A neckloop earns its keep in two gaps Bluetooth doesn’t close: older phones, landlines, and laptops with no Bluetooth pairing option, and public hearing loops in theaters, churches, courtrooms, and transit hubs, which broadcast a magnetic signal to telecoils, not a digital signal to Bluetooth radios. If you regularly sit in looped venues or rely on a non-Bluetooth phone, a neckloop is worth the $40–$70 even if your hearing aid streams Bluetooth for everything else. Our assistive listening devices roundup covers the full range of venue and TV accessories beyond just neckloops, and our best hearing aids for TV picks cover the dedicated-headset alternative if your hearing aid has no telecoil at all.
A quick health note
A neckloop is a passive audio accessory, not a treatment, and it does nothing for a hearing aid without a working telecoil. OTC hearing aids are intended for adults 18 and over with perceived mild-to-moderate hearing loss in both ears. If you have severe or profound loss, sudden hearing changes, hearing loss in only one ear, ear pain or drainage, or tinnitus that is pulsing or one-sided, see an audiologist or physician rather than relying on any accessory to compensate.
The bottom line
If your hearing aid has a telecoil, a neckloop is one of the best five-dollar-per-year accessories in hearing care: the Williams Sound NKL 001 covers general phone, TV, and venue use for most buyers, the Bellman & Symfon Neckloop trades a little versatility for all-day comfort and a safety clasp, and the ClearSounds CLA7-V2 is worth the extra amplification if phone calls are your main pain point. Check your telecoil first — with fewer than 6 in 10 current models carrying one, that single confirmation matters more than which neckloop you pick.
