Having researched the options and spent ages comparing brands in-store, I went back to a trusted name and have not regretted it. The sound quality is excellent - meaning not just quality of playback but the effective attenuation of ambient noise through well-designed in-ear cups, bearing in mind...

￡80ish for a smashing sounding set of Bluetooth headphones. Does exactly what the doctor ordered. Full charge lasts me well over 10 hours. Cant fault them. The only con is the wee ouch itscome with to store them. A nice little case would've been much better.

In North America, Sennheiser is best known for its professional-grade monitor headphones, microphones, and the sort of speakerphone hardware that you'll find in an upscale office environment.

Frequent connectivity issues, a lack of waterproofing, and less than stellar sound make Sennheiser's CX 7.00BT in-ear wireless earbuds difficult to recommend. There are other more capable earphones available--many of which we've reviewed--that would be a wiser investment.

Lightweight; Stylish design; 10 hours of runtime between charges

Thin earbud wires prone to microphonics; Poor passive noise cancellation; Water resistance claimed; but no IPX rating provided; High frequency audio can sound a bit shrill

I got these as an alternative to my current JBL E25BT ear buds, which I found rather clumsy with the cable and middle battery pack. These support aptX BT streaming, much better sound when coupled with FLAC audio files.

I have only had this less then a week and I already think it's one of the best wireless headphones I've seen and had. I was so unsure about spending so much on a pair of headphones.

Sennheiser have been hitting a real purple patch lately, and the new CX 7.00 BT is no exception. The new neckband design looks and sounds gorgeous. With its 10-hour battery life, you won't be left without your tunes on a long commute either. At $150 USD (£130, $250 AUD) the CX 7.00 [...]

Balanced; bass-focused audio Four eartip options 10-hour battery life Quality build

On the heavier side Case doesn't provide much protection

It's already October and the year is nearing a close but not without a few more headphone surprises from Sennheiser. The latest one is Sennheiser's second in-ear wireless headphone ever and it's called the .

As far as everyday listening is concerned, Sennheiser is spot on in describing its new Bluetooth earphones as a pair for the "fast-moving, always-on generation".
