London GB
Comfortable to wear

I found controls easy to grasp BUT I have owned previous versions of this device

Sound quality good enough for a run

Good for audio-only media
Can take a while to bluetooth-connect to my device

Lag in transmission means I cannot use it to watch videos (so it can't be for overall use - keep it to sport and audio only)

Prior warning of low battery or a qay to check charge would be good as I have had instances where it just died in the middle of a work out

Delivering your online order

Get this delivered when it suits you

We’ll show you your current delivery options for this item in checkout. Subject to the time you order, and where you want delivery, these options will include:

  • FREE standard delivery in 5-10 working days
  • Next day delivery or any following day between 8am & 5pm (£5.00)
  • Delivery in a timeslot of your choice next day or any following day (£10.00)
Please note: if we’re out of stock of an item but getting more in, we indicate – on listings pages and the product page – how soon we can dispatch for delivery to you. In this case, please go ahead and order, and we’ll contact you later to confirm an exact delivery date.

Important update on our delivery service for small items

Our courier partners (DPD, Royal Mail and On the Dot) have all updated their delivery processes to take extra precautions due to Coronavirus (COVID-19). Please follow the below advice:

1. Customers can use the DPD app to nominate a ‘safe place’ for their delivery to be left if they do not want close contact.

For customers unable to use the DPD app, DPD is still able to offer a contact-free delivery, and will take a picture of the property and capture a proof of delivery name instead of capturing a customer signature.

2. Royal Mail is an unsigned service . Where Royal Mail needs to deliver a parcel, its teams will place the parcel at the customer’s door. Having knocked on the door, the delivery teams will step aside to a safe distance while the item is retrieved. If the delivery cannot take place, Royal Mail will take the parcel to the local depot for collection by the customer.  The parcel will be held for 18 days as per normal process.

3. For On the Dot, where a standard signature delivery is not possible, On the Dot will attempt to leave the parcel in a safe place and inform the customer of where the parcel has been placed.

To see the courier partner for your delivery, please check your dispatch confirmation email (which will also include your tracking reference).
