After doing a quite a bit of info gathering I finally went to Costco back in Nov 2012 and purchased a pair of Chronos 9’s. I thought I would post my impression:
This is my first set of HA’s. I briefly tried some Agil’s but didn’t want to spend $300 for a 30-day :rolleyes:…anyway, so I do not have anything else to compare these to. <O:p
I have the basic remote, which has worked fine for me.
<O:pThe initial programming was:
<O:p1) Multi Environment
<O:p4) Live Music
With the “canned” download computed from my audiogram, programs 2 and 4 were gained way too high so feed-back was a pain. Also, the Telephone setting was a waste since the HA’s worked just fine with my office land line and my mobile with the HA’s set to Multi. I had the gain issues sorted out on my first adjustment visit and also had the Telephone program replaced with a different one (I think Large Conference or something) so the HA’s are at least in the ball park now. <O:pThe first thing I noticed was the huge amount of compression in the Multi setting. It made riding/driving in a vehicle a very weird experience. Every time the vehicle hit a tar strip or some other highway imperfection that causes a thump (low frequency event), the gain across all frequencies was momentarily reduced. That made listening to music or having a conversation in a car impossible. Fix? The Live Music program has compression dialed way back so that is the one I use when driving and it works okay.
There a couple of annoyances that I don’t know if they are specific to digital HA’s in general, this model, or just programming:
- While the gain in the 1-4khz region improves speech intelligibility, it seems to accentuate the noise more than the speech. For example, if I am talking to someone in the kitchen and the faucet is turned on, speech is entirely buried in the hash made by the running water. From all the reading I did on this forum I kind of expected this initially but I have been wearing these HA’s 10-12hrs/day for almost 90 days now so would think my brain would have had time to sort some of that out. I wonder sometimes if the HA’s are over processing the input signal in the attempt to make speak stand out.
- Something I notice in theatres and other settings where I am sitting in a group of people is that speech immediately behind me is clearer than speech directly to my right or left. Weird. I feel like I am eaves dropping. Lol. Sounds like possibly a mic directionality issue?
- I am a musician and am disappointed in the frequency response above 4k (virtually rolled off from the graft I saw when the units were being programmed) I asked the fitter about that and was told that the frequency response (little gain above 4k) was typical. Whether or not that is correct I do not know but I have resorted to using an EQ unit to pump the gain up in the 6-12khz range in my headphone amp to restore some of the detail up there.
<O:pWhile my comments may seem a bit negative I know HA’s are a step in the right direction. When I take these off at night it is like someone pulled the plug on my audio world.</O:p
