About ISOtunes

ISOtunes sells Bluetooth hearing protection headphones and earphones for work, shooting and hunting, made by Haven Technologies, a family business founded in 2016.

This is the EU store, priced in euros and shipping from Germany. No shipping price or free-shipping threshold is posted, so the 10% email sign-up code is the clearest saving on offer.

ISOtunes comes from Haven Technologies, whose founders previously spent 20+ years in consumer safety at Aearo Technologies, 3M and Honeywell. The company is headquartered in Carmel, Indiana, with further offices in Germany, Canada and the UK, and it launched the ISOtunes Sport line for shooting in 2021.

Headphones include the LINK 2.0, LINK Aware and DEFY Slim, while earphones range from the PRO 3.0 and FREE 2.0 to the FREE Aware and CALIBER. Aware Technology lets wearers hear the people around them, and Tactical Sound Control is designed to cut out gunshot noise while keeping music and speech audible. The EU site sorts products by activity, from workshops and farming to motorsport and travel, and has recently added a wearable speaker.

How to use a ISOtunes discount code

  1. The EU store uses Shopify's standard checkout, which puts the discount box in the order summary of the checkout page.
  2. A gift card and one discount code can go on the same order, which helps if someone gave you credit.
  3. Buying a gift card yourself is a different story, because gift card purchases are excluded from website discounts.
  4. The sign-up code takes a percentage off, so it goes further on an ULTRACOMM Aware than on a passive set.

If your ISOtunes code doesn't work

  • Exclusions: Gift card purchases are excluded from website discounts.
  • Combining offers: A gift card can be used together with one discount code.
  • New customers only: 10% off a first order (join the email list for 10% off your first order) does not apply to repeat orders.

More reasons a code fails, and what to try: why promo codes don't work.

More ways to save at ISOtunes

  • Your first order gets 10% off once you're on the email liSt. For Black Friday, ISOtunes runs a VIP access sign-up page, though it lists no dates or discount.
  • E-gift cards never expire and can be refunded to the original payment within 30 days of purchase.
  • They can't be cashed out or used to buy another gift card.

ISOtunes questions, answered

Are ISOtunes worth the money?

Products sold in Europe are tested to the EN 352 hearing protection standard, with output capped at 82 dB. A 30-day money-back guarantee and a 1-year warranty against defects lower the risk of trying a pair.

How do you get a valid ISOtunes discount code?

Sign up to the ISOtunes email list and you'll get 10% off your first order. Gift card purchases don't take website discounts.

What stores sell ISOtunes?

In Europe, ISOtunes sells direct through its EU site, which ships from a warehouse in Germany. Shoppers outside the UK and EU, including the US, are pointed to the North American site ISOtunes.com.

What time is the same-day shipping cut-off?

Weekday orders placed by 1 pm ship the same day. The delivery policy gives that time in GMT while the FAQ gives it in CET, so order early to be safe.

Who pays for return shipping on an ISOtunes order?

The return policy doesn't say who covers return postage. Email support before sending anything back, since that's the first step anyway.

Who pays customs duties on ISOtunes orders?

Customs duties outside the UK are the buyer's to pay. European orders ship from a warehouse in Germany, and the EU store lists a Hamburg address.
