The Resound Linx 3D 7 is the second most advanced model in the Resound Linx 3D range of hearing aids. Unlike many hearing aid ranges this does not mean that it is a mid-level aid, it just means that is slightly less technologically sophisticated than the Resound Linx 3D 9 which is the premium aid in this range. The Linx 3D range also features the Resound Linx 3D 5 which is more what we would describe as a mid-level hearing aid. If you are looking for a more basic entry level aid then you would probably be better off looking at Resound’s older Enya range.
The Resound Linx 3D 7 is essentially just a slightly less expensive version of the premium Linx 3D 9, but to justify the cost saving it features less sophisticated versions of some of the Linx 3D 9’s technological features. The main differences between the Linx 3D 9 and the Linx 3D 7 include:
The Linx 3D 7 features Resounds older version of this technology, as compared to the ‘Binaural Directionality III’ version present in the Linx 3D 9. This older version of the tech is by no means obsolete and in fact still does a very good job, however you don’t get the same levels of spatial awareness which could leave some users feeling a bit lost in their sonic landscape.
This function is only available in the Linx 3D 9, so as above, you may find it more difficult to identify where sounds are coming from.
The Linx 3D 7 features the ‘Advanced Noise Tracker II’ rather than the ‘Advanced Noise Tracker Ultra’ found in the Linx 3D 9. This feature aims to improve the ability to identify and understand speech when in noisy situations. The Linx 3D 7 version is still effective, it just lacks the extra power and clarity that you get from the ‘Ultra’ version.
This function, present in the Linx 3D 7 allows your hearing aids to adjust quickly and smoothly to even rapidly changing sound environments. Again this is a perfectly adequate function, however it lacks some of the clarity and edge over the ‘Binaural Environmental Optimiser II’ that is present in the Linx 3D 9.
The Linx 3D 7 only has 14 warp channels, compared to the Linx 3D 9’s 17. Warp processing is a process by which the hearing aid warps frequencies to replicate the way that your ear would naturally break sounds down into distinctive pitches. Each channel analyses and warps different frequency ranges (which also overlap). The higher the number of channels the more naturally the sound waves can be processed by your inner ear.
This feature is missing entirely from the Linx 3D 7, only being available in the Linx 3D 9. It allows functions and settings to be tailored to meet your specific needs and preferences, rather than having to choose from a number of more general settings.
Although this function is present in the Linx 3D 7, it is less sophisticated than in the Linx 3D 9. Annoying wind noise is isolated and inhibited, although to a lesser degree than in the more expensive Linx 3D 9.
As you can see there are a number of differences between the Linx 3D 9 and the 3D 7, but then there is also a considerable cost saving, especially if you are buying 2 hearing aids. In our opinion the Linx 3D 7 is still a very good Resound hearing aid and could do many users very well, unless you require the more sophisticated technology of the Linx 3D 9.

Do not spend hundreds of pounds without getting a second opinion from us.
If you are looking at this page then it is likely that an audiologist has suggested that you purchase this particular hearing aid, so is this the best model for you?
In general, any audiologist will always be recommending to you the model that best suits your needs. Here is a useful check list to make sure that is the case.
If in doubt, feel free to give us a call. That's what we're here for.
If you have a significant hearing loss in both ears, you should be wearing two hearing aids. Here are the audiological reasons why:
Localisation. The brain decodes information from both ears and compares and contrasts them. By analysing the miniscule time delays as well as the difference in loudness of each sound reaching the ears, the person is able to accurately locate a sound source. Simply put, if you have better hearing on one side than the other, you can't accurately tell what direction sounds are coming from.
Less amplification required. A phenomena known as “binaural summation” means that the hearing aids can be set at a lower and more natural volume setting than than if you wore only one hearing aid.
Head shadow effect. High frequencies, the part of your hearing that gives clarity and meaning to speech sounds, cannot bend around your head. Only low frequencies can. Therefore if someone is talking on your unaided side you are likely to hear that they are speaking, but be unable to tell what they have said.
Noise reduction. The brain has it’s own built in noise reduction which is only really effective when it is receiving information from both ears. If only one ear is aided, even with the best hearing aid in the world, it will be difficult for you to hear in background noise as your brain is trying to retain all of the sounds (including background noise) rather than filtering it out.
Sound quality. We are designed to hear in stereo. Only hearing from one side sounds a lot less natural to us.
For most people, the main benefit of a rechargeable hearing aid is simple convenience. We are used to plugging in our phones and other devices overnight for them to charge up.
For anybody with poor dexterity or issues with their fingers, having a rechargeable aid makes a huge difference as normal hearing aid batteries are quite small and some people find them fiddly to change.
One downside is that if you forget to charge your hearing aid, then it is a problem that can't be instantly fixed. For most a 30 minute charge will get you at least two or three hours of hearing, but if you are the type of person who is likely to forget to plug them in regularly then you're probably better off with standard batteries.
Rechargeable aids are also a little bit bigger and are only available in behind the ear models.
Finally, just like with a mobile phone, the amount of charge you get on day one is not going to be the same as you get a few years down the line. Be sure to ask what the policy is with the manufacturer warranty when it comes to replacing the battery.
For most people, the answer is yes. But it's never that simple.
The majority of hearing problems affect the high frequencies a lot more than the low ones. Therefore open fitting hearing aids sound a lot more natural and ones that block your ears up can make your own voice sound like you are talking with your head in a bucket. Therefore in-ear aids tend to be less natural.
However the true answer is we can't tell until we have had a look in your ears to assess the size of your ear canal, and until we have tested your hearing to see which frequencies are being affected.
People with wider ear canals tend to have more flexibility, also there are open fitting modular CIC hearing aids now that do not block your ears.
There is also the age old rule to consider, that a hearing aid will not help you if it's sat in the drawer gathering dust. If the only hearing aid you would be happy wearing is one that people can't see, then that's what you should get.
Most people can adapt to any type of hearing aid, as long as they know what to expect. Have an honest conversation with your audiologist as to what your needs are.
Generally speaking, six or more. Unless it's none at all.
The number of channels a hearing aid has is often a simplistic way an audiologist will use to explain why one hearing aid is better than another, but channels are complex and it is really not that straightforward.
Hearing aids amplify sounds of different frequencies by different amounts. Most people have lost more high frequencies than low and therefore need more amplification in the high frequencies. The range of sounds you hear are split into frequency bands or channels and the hearing aids are set to provide the right amount of hearing at each frequency level.
Less than six channels and this cannot be done with much accuracy, so six is the magic number. However, a six channel aid is typically very basic with few other features and is suitable only for hearing a single speaker in a quiet room. The number of channels is not what you should be looking at, it's more the rest of the technology that comes with them.
As a final note, different manufacturers have different approaches. One method is not necessarily better than any other. For example some manufacturers have as many as 64 channels in their top aids. Most tend to have between 17 and 20. One manufacturer has no channels at all.
When we refer to a product as 'New', we mean that the product is new to the market.
When we refer to a product as 'Superseded', we mean that there is a newer range available which replaces and improves on this product.
When we refer to a product as an 'Older Model', we mean that it is has been superseded by at least two more recent hearing aid ranges.
