After getting the Bluetooth board, refer to the wiring diagram below to solder the speaker and 3.7V lithium battery, and then check that the battery is not connected reversely. You can turn on the power test. Turn on the switch and the blue indicator light should light up. If it does not light up, you should quickly turn off the power to check whether the battery is installed correctly. When the indicator light is on and there is a ding-dong prompt sound, you can turn on the mobile phone Bluetooth to refresh the Bluetooth name, find "DAU Audio" to connect and play the music on the mobile phone. Regarding TWS pairing, if you buy two DAU Audio Bluetooth modules, they can be paired in stereo. You need to turn off the Bluetooth of your mobile phone first, then turn on both boards at the same time, wait for a few seconds to hear the prompt tone, then the blue indicator light of one module is always on, and the indicator light of the other module is still flashing, indicating that the TWS pairing is successful. Then turn on the mobile phone to connect Bluetooth, and you will have a stereo wireless speaker.

Please allow additional shipping time for deliveries to exceptional locations that are hard to reach, and also during busy periods such as Christmas.

All carriers deliver during normal business working hours and may require a signature on receipt, so please ensure your order is delivered to an address where someone will be available to accept it.

We do our best to ensure that the products that you order are delivered to you in full and according to your specifications. However, should you receive an incomplete order, or items different from the ones you ordered, or there is some other reason why you are not satisfied with the order, you may return the order, or any products included in the order, and receive a full refund for the items.

Certain products purchased at Fruugo cannot be returned. They fall in the following categories:

  • goods which are clearly personalised or made to your specifications
  • goods which are liable to deteriorate rapidly, eg fresh fruit, fresh flowers
  • sealed goods which are not suitable for return due to health protection or hygiene reasons, if opened, eg make up, underwear, pierced jewellery
  • sealed audio or video recordings or computer software, if opened
  • newspapers, periodicals and magazines

Please take reasonable care of the goods whilst in your care. Any goods returned must be in a resaleable condition. They must be unworn/unused with original tags attached and in original packaging. It is your responsibility to ensure that the goods are appropriately packaged to ensure they are not damaged in return transit.

  • your name,
  • order number,
  • the item(s) you wish to return, and
  • optionally a reason for your return: unsatisfied with item, item didn't match description, damaged item, wrong item, or some other reason.

Our customer care will send you specific instructions on how to ship the return package(s) to the retailer(s). Please do not ship the return package before you receive the instructions.

Shipping products back to retailers

Goods must be returned without undue delay and in any event not later than 14 days after notifying us of your cancellation.

If you are returning products to several retailers, you should distribute the products accordingly and send the products to those retailers who shipped them to you initially.

We strongly recommend that you use registered mail (and insure any high-value packages), since neither Fruugo nor the retailer take responsibility for shipments that are lost or damaged during return transportation.

Unless a product or products you wish to return arrived to you damaged or faulty, you are responsible for the return transportation costs.

Providing you are returning all the products from a specific retailer, we will refund the standard shipping costs you paid for the original delivery. If you chose to pay for a non-standard delivery, we will only refund the cost of our least expensive, standard delivery.

  • your name,
  • order number,
  • name of the damaged product(s), and
  • state the nature of the damage with attached photograph

We will generally instruct you to ship the damaged product back to the retailer. As soon as it reaches the retailer, they will send you a replacement product. If the replacement can't be made, or if you wish to cancel the order, you will be refunded in full. You will also be reimbursed for reasonable returns postage costs for damaged or faulty goods once we have received your postage receipt.

If the outer packaging of your order is clearly damaged on arrival, and you are suspecting that the products are damaged as well, you can either reject the delivery or accept the goods and sign for them as damaged. In both instances, please notify Fruugo customer care as soon as possible.

Refusing delivery

If you refuse to accept delivery of all or part of your order (where the products or packaging do not appear to be damaged or defective) you will be responsible for the postage charges.
